Package Kit: reduce identifer/base-url confusion

For historical reasons, the package kit has an "url" field that is not
actually meant to be used as an URL. Rename it in the API and user
facing output as "identifier" to make it clear what the file is used
for. This change preserves the "url" key in on-disk and online storage
(hpkr files, stored settings, etc) in an attempt to not break anything.

Fix one remaining misuse of the "url" field as an URL in
get_package_dependencies.

Add an unit test showing that BUrl does parse "tab" URIs properly (there
is just a protocol and a path segment).

pkgman: fix for syntax (help)

The tool "pkgman" was not showing it's help text
and this seems to be somehow related to the
initialization of constants such as
"kCommandCategoryPackages"; these values seems to
be coming through as empty-string for some reason.
I am changing those to be "#define" of regular
C-Strings and this seems to resolve the problem.
These values only seem to be used to group the
possible commands for production of the syntax or
help text - there do not seem to be any deeper
impacts beyond that functionality.

HaikuDepot / PackageKit: Repositories 'Identifier' URL

Repositories are identified with a 'url' in the
remote 'repo.info' file. There is also a
'base url' which is the URL locally with which
the system is able to access the repository
data on. There is some confusion between these
two terms in the source. This change aims to
separate the two out and consistently name them.
The settings for the repository locally also was
not storing these values and that has been fixed.
Debug info about the repositories also did not
display the two urls consistently and will now
also do so. Finally, HaikuDepot now correlates
locally configured repositories with the data in
HaikuDepotServer using the identifier URL; this
makes the use of mirrors with HaikuDepot possible.

Fixes #13888

Revert "repo rework: Re-add compatibility url field"
Revert "repo rework: Remove stubs; Breaks repo compat."
Revert "repo rework: Remove need for repos to be self-aware"

This reverts commit a2b2f4d6427914cdcdb59943dd8e4a0bfdcd53ee.
This reverts commit 602076ef82647a48fd10f4d1ec830bb4242f9eb6.
This reverts commit 5ffaf72c8a74a7eb6827e4d2b1f47c9360ddaefe.

These changes break the build on Haiku and the ability to create repo
mirrors, for the lack of a replacement for the URL (an UUID was evoked
on the mailing lists, but not implemented).

We are due for a release soon, please don't break the build.

repo rework: Remove need for repos to be self-aware

* See #12917 for details.
* Squashed to one commit to make revert easy if we
run into any issues.
* pkgman is now pre-attached to the 'current' repo
version within nightly images so they can be updated
by default.
* This shouldn't impact us keeping older sets of package
versions by commit hash for building older hrevs.
* There are XXX stubs with "Kill me". These will need
to be dropped after users are given sufficent time to
upgrade. We're dropping a previously required field (url)
so making this a slowish roll out.
* Makes the repos a lot less restrictive which should
help PM package building automation be a bit easier.
* Once this stuff smooths out, we'll add UUID's to the
repo definitions for duplicate repo detection.

Fix build of pkgman on x86_64 by use of B_PRI... define.

pkgman: Organize commands by category

pkgman: C++-ify the command handling

There's now a Command class that must be derived and registered with
a CommandManager, all simplified by a REGISTER_COMMAND macro. That gets
rid of the print_command_usage_and_exit() function copy for every
command, moves the short usage texts to the command implementations,
and avoids any repetition of the command name. When implementing a new
command only a new source file needs to be created, nothing else needs
to be touched.

Use BStringList in package kit

Replace all instances of BObjectList<BString> by BStringList.

BRepositoryCache: Add iteration, etc.

* Remove InitCheck() and the initializing constructor.
* Rename PackageCount() to CountPackages().
* Use BOpenHashTable instead of HashMap for the internal PackageMap.
* Allow multiple packages with the same name. Equally named packages are
in a singly linked list after the first package with that name.
* Add an Iterator inner class and a GetIterator() method, so one can now
iterate through the packages in the repository.

Mostly style-related changes to package kit:
* drop 'Haiku' namespace
* rename 'Package' namespace to 'BPackageKit'
* renamed all public classes to begin with a 'B'
* renamed BPackageKit::Roster to BPackageKit::BPackageRoster to not
clash with the BRoster from the application kit.
* fix some instances of public headers including private ones

Some functional changes, too:
* JobQueue now removes and deletes dependants of failed jobs
automatically
* JobQueue supports waiting for jobs to become runnable
* added a couple of InitCheck() methods where they make sense
and invoke those in users of these classes
