HaikuDepot: Set package state when loading single package

Without this, even installed packages still get an "Install" button.

Fixes #14821.

This was implemented by adding BPackageRoster::IsPackageActive. I decided to
have this take a location since GetActivePackages also did, but as noted in my
TODO comment, I think this is awkward.

It would also be nice to show the user they have a different version of a
particular package, but that would require some changes to IsPackageActive.

Package Kit: Avoid discarding potential error values.

Spotted by Clang and the [[nodiscard]] patch.

Add Reboot Check to BPackageRoster

A bit of an explanation for these weirdly named functions:
LatestActivePackageInfos() returns the packages on the system that are
both installed and fully set up. When packages are in the middle of being
installed, LatestInactivePackageInfos() shows the packages in the process
of being installed. Once the installation process is done,
LatestInactivePackageInfos() returns nothing. If there are packages that
can't be fully activated without a reboot, CurrentlyActivePackageInfos()
will return the same information as LatestActivePackageInfos(), or if
everything has been installed and activated, it will return no packages.

Add watching support for installation location package changes

Can be requested/stopped via BPackageRoster::{Start,Stop}Watching().
The notification message has the what code B_PACKAGE_UPDATE and contains
fields "event", "location", and "change count".

InstallationLocation: Rename [in]activePackages properties

Add prefix "Latest".

Remove /boot/common for good

* Remove support for the "common" installation location from packagefs,
package kit, package daemon, package managers.
* Rename the B_COMMON_*_DIRECTORY constants referring to writable
directories to B_SYSTEM_*_DIRECTORY.
* Remove/adjust the use of various B_COMMON_*_DIRECTORY constants.
I'm sure some occurrence still remain. They can be adjusted when the
remaining B_COMMON_*_DIRECTORY constants are removed.

Implement getting a BInstallationLocationInfo

* Rename PackageDaemonDefs.h to DaemonDefs.h.
* Replace the MESSAGE_GET_PACKAGES by the new
B_MESSAGE_GET_INSTALLATION_LOCATION_INFO, which not only returns the
packages, but also other information about the installation location.
* daemon: Volume: Implement a change count which is bumped whenever
packages are activated/deactivated/added/removed. Cache the reply
for a location info request, using the change count to check whether
it is still up-to-date.
* Add private BDaemonClient for communication with the daemon.
* BRoster:
- Add GetInstallationLocationInfo() using BDaemonClient.
- Reimplement GetActivePackages(), using
GetInstallationLocationInfo().

package kit: get active packages list from daemon

* daemon: Implement private message protocol to retrieve the active
packages.
* BPackageRoster::GetActivePackages(): Get the active packages list
from the daemon.

Add BPackageRoster::GetActivePackages()

The implementation is temporary. Currently it reads through the packages
in the respective packages directory and checks against the package
links. Once package activation is tracked explicitly we'll use the
activation file/directory.

Use BStringList in package kit

Replace all instances of BObjectList<BString> by BStringList.

GetRepositoryCache/Config(): return valid entry

Always create the common repository cache/config paths so the BEntry
that is returned is valid at least. Fixes BRefreshRepositoryRequest
failing when the common repository cache path didn't exist yet.

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
