Package Kit: Purposely ignore an error getting package cache

Fixes #15230.

The comment pretty much explains it. I think needing this means this code could
be redesigned, but I don't know enough yet to make that fix.

It also feels like this whole job system and Command pattern is overly
complicated when good old functions would be fine, certainly for pkgman. But
maybe this is used more heavily in HaikuDepot.

Package Kit: Avoid discarding potential error values.

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

Moved BJob, and JobQueue into the support kit.

* Put it in the BSupportKit namespace, following the style introduced
with the package kit for now.
* The BSupportKit::BJob class no longer knows about the package kit's
Context class. However, the BPackageKit::BJob class does.
* Due to the namespace juggling, a lot of files had to be touched.
* The JobQueue class remains private.
* Due to the way Haiku is built on itself, you cannot build this change
under Haiku with an older release.

more work on package kit:
* rip BRepositoryHeader out of BRepositoryConfig and add support
for it to BRepositoryCache
* implement repository removal
* some minor cleanups


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@40290 a95241bf-73f2-0310-859d-f6bbb57e9c96

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



git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@40287 a95241bf-73f2-0310-859d-f6bbb57e9c96

* more work on the package kit, repositories can now be added and
refreshed
