HaikuDepot : Improve Language Code Handling

HDS is soon going to be enhanced to deal with more than
just the two-character ISO language codes that it
currently supports. The logic in HD is currently expecting
that HDS will only supply these two character codes. This
change is about making adjustments to be able to cater to
any ICU language IDs from HDS.

The naming in HDS is still going to continue to use the
terminology that it currently does; it will call the
identifier for a language a "natural language code". The
HD source will instead reflect the nomenclature of ICU
and call the same thing a language ID.

HaikuDepot: Fix Crash on Shutdown

The MainWindow itself was a BReferencable via a listener
virtual class. It looks like the error has come from a
conflict between the MainWindow's own deletion and the
state of the reference count. This change moves the
listener / BReferencable out of the MainWindow so that
the lifecycle of the BReferenable can be managed
correctly.

A further problem here is that the new listener
was leaked from the MainWindow class on shutdown.
To resolve this problem requires a considerable
change to the "process coordinator" system.

HaikuDepot: Icon / Tarball Handling

Instead of exploding the tar-ball of icons from
HDS, keep it as a tar-ball, index it and read
data directly out from specific indicies on demand.

This will speed up the process of downloading
the icons by removing the unpack. Also updates
will be faster by avoiding the need to delete the
old icon files.

Because icons are loaded on-demand, the start
time is faster by avoiding all the icon loads.
There are also savings on memory consumption.

Indexing on each load is surprisingly fast so
no external index is maintained. Likewise for
the tar-balls's meta-data.

This commit does not cover the implementation
of an LRU cache of the icons in memory.

HaikuDepot: Performance

This change removes two mistakes I made a long time ago
that caused unnecessarily copying of lists of data. This
fix speeds up the UI alot.

This change also clears data in UI list elements when a
bulk load is requested. It stops clearing otherwise and
instead uses "add" and "remove" operations in the lists
which is OK now because the UI list elements are much
faster than they have been in the past. This removes
the strange clean-and-reload that was visible in the UI
previously.

A threaded package loading system was put in place a long
time ago, but with these performance improvements this
mechanism is no longer necessary; it has been removed to
simplify the code.

HaikuDepot: Process and Data-loading Improvements

This change is a reshuffle of the backend processing involved in the
aquisition of data from servers including the pull-down and load of
HPKR data as well as the pull-down and load of data from the
HaikuDepotServer (HDS) system. The driver for this change is to
implement an initial implementation of a progress bar for the
loading of data as the application starts.

The following are notable changes;

* Removed some previously attempted 'functional style' logic in the
model which didn't fit well with C++
* Use of the base-url in the logical mapping from HDS and HD data is no
longer required and has been removed
* Some logging has been improved making it clearer which part of HD
is producing the logging which in turn helps with debugging issues
* List class has been modified to more cleanly support sorted lists
and binary searches; tests have also be updated accordingly
* Reorganise and tidy-up of the data-loading processes' structures
* The local repository update (HPKR) and data-load occur in background
processes now in the same system as the HDS data-load - this has been
crudely shifted from the MainWindow to new Processes and incorporated
into the background processing system
* The 'state-machine' background process runner is now replaced with a
'coordinator' style approach that can more easily handle the new
processes related to HPKR loading.
* Progress for loading processes is shown in the main window in the
WorkStatusView - this is flickering a bit, but basically works
* Added some documentation regarding how Processes work in the system
* The "Refresh Repositories" menu item now also updates data from HDS
* The "Refresh Repositories" menu item is disabled when the background
processes are running that update the repository data

Some further refinement would be good, but this change is large enough
for one round of improvements. There is an issue that the status bar
is used for screenshot display as well as this data-loading, but that
was the case before so it is something that can be dealt with later if
it is a problem.

HaikuDepot: speed up package change handling

* During package population, when the repository is being
refreshed, thousands of package change messages arrive
in MainWindow while the PackageInfo fields are filled with
data.

Every such message caused a full generation of a package
list (including applying filters to all known packages),
which is quite slow, and caused the freezing from bug
#13823. The list was only used temporarily to figure out
if the package should be visible now or not.

* Instead of generating a new package list, we now only
match the single updated PackageInfo against the current
filters.

* Fixes #13823

* To reduce CPU usage even more, it would be better to not
generate at all, or not subscribe to, package changes while the
list is being initially populated, and/or to coalesce all the
changes to each package info into one update message (instead
of one for title, one for prominence, etc).
Deferring subscription requires some additional thought on when
to subscribe then, and how to avoid leaving a "hole" where
changes would go unnoticed.

* Moves the bulk-load logic out of the data-model

* Implements concurrent loading of the bulk-data to

* Loads data to a temporary file and then moves to the
final location in order to avoid partially written
data in the cache.
* Handles situations where no network is available;
prevents attempt to access the network.
* Allows bulk-load processes to be cancelled when the

network absence.
* Implements ordered insert and binary search in the

HaikuDepot: New Mechanic for Package Data Download

The application was previously making a number of different
requests to the application server in order to pull-down
meta-data (ratings, localization etc...) for packages. This
will now happen in one request per repo. The data is
also cached locally and freshness of the data is checked
back with the server before new data is pulled down.

HaikuDepot: Improved logging control

The application had previously no means to control the verbosity of
logging. This excessive logging meant that it was bit hard to
understand what is going on. Now it is possible to define the level
of logging that is output; especially as the application pulls-down
data from the remote server system.

HaikuDepot: Change communication mechanism with server for repos

(last commit with same title only included new files - added those now)

Previously the desktop application would make a number of JSON-RPC calls
over HTTP to get the repositories. Now it will make a single call to get
the repositories and cache the result. This uses standard HTTP cache
signalling techniques and allows the server-side the ability to cache
the generated data as well. Note that the model classes and parse-
related classes are generated and may not be code-style compliant. They
are generated from JSON schema files in the server-side project.
Information about this as well as the python files used to generate the
C++ classes and headers are included in the server-side project.

HaikuDepot: format string fixes.

HaikuDepot: Improve icon download handling performance

Previously each icon would launch an independent HTTP request to
pull down the HVIF icon data. This change means that the data
will be pulled down in bulk across all packages as a .tgz and
will then be kept in a cache locally. The client-server logic
will use standard "If-Modified-Since" headers to check for
updates each time the HaikuDepot desktop application starts up.
This arrangement will bring down the HVIF as well as bitmap
icons and use the best representation it can.

Additionally, it is possible from a command-line option to log
HTTP traffic verbosely and it is also possible to use an "-h"
flag to display help on command-line arguments.

The code-structure around this change also anticipates some
future extensions to handle other client-server improvements.

Model: Pull changelogs from the package infos

HaikuDepot: Clean up trailing whitespace.

HaikuDepot: Re-activated Size-column

Noticed that HaikuDepotServer info now contains "payloadLength", which is
the package size. Populate that in the list view.

HaikuDepot: Title versus Name distinction

* The name is the static package name. The title is either that name,
or a translated pretty version of the name.
* Adjust package info retrieval to server API changes. Unbreaks package
translations.

HaikuDepot: Implemented light-weight package manager update

No, not updating packages via HaikuDepot, but a light-weight synchronization
between the system package manager list and the HaikuDepot model. After
installing or removing a package, HaikuDepot performed a very costly update
of all information by basically throwing everything away and reloading it.
Implements #11786.

HaikuDepot: Update package info after rating package

Let Model::PopulatePackage() have a mode where it forces the update on a
package that has already been populated. Trigger populating from success
code path in RatePackageWindow. Fixes #11638.

HaikuDepot: Search all packages when showing featured

The intention was that typing search terms searches all packages, not only
the featured ones. This didn't actually work in Model::CreatePackageList().

HaikuDepot: Change when featured packages are shown

* Renamed the "Option" menu to "Show", removed the now redundant "Show" from
the items in that menu.
* Add an "Only featured packages" item in the Show menu. This item is disabled
as soon as the user types something in the search terms field. Othetwise,
this setting is respected, i.e. one can combine the featured setting with
other settings, i.e. show all featured packages of a certain depot and in a
certain category.
* Added PackageInfo::IsProminent() and removed the respective method from
the MainWindow (which only considered a package prominent if it was not
yet installed).
* "Show -> Installed packages" now defaults to on. There have been complaints
on Trac and I guess rightfully so. The use-cases in which one starts
HaikuDepot and wants to know about installed packages are just as likely
as the use-case where one wants to install new software.

HaikuDepot: Add some getters to Model.

For category, depot and search terms filter.

HaikuDepot: Retrieve prominence values from web app

HaikuDepot: Fixed potential dead-lock in package list refresh.

When the package list was refreshed while package info was still being
pulled from the web app, calling Model::Clear() with the model lock already
held could lead to a dead-lock: The package populator could block on the
model lock to update information, while StopPopulatingAllPackages() waited
for the thread to exit, but held the lock that the thread was blocking on.
So call StopPopulatingAllPackages() before grabbing the lock and calling
Clear() in MainWindow::_RefreshPackageList().

HaikuDepot: Enable caching of info retrieved from web-app

HaikuDepot: Restore logged in user across sessions.

* Store the username in the app settings. The password was already stored
in the keyring. Restore the username upon next launch.
* Display the logged in user in the main window.
* Added "Log out" menu entry.
* When the password could not be retrieved from the keyring (also because
the user rejects the keyring dialog), unset the username.
* Allow unsetting the username by passing an empty name.

HaikuDepot: Put supported languages into a StringList

* Added TODO to retrieve the list from the web-app, there is already an
API for it. For now, the hard-coded list matches the web-app's and the
next change in this regard will be to support any known language.
* Make the list accessible.
