[packagekit] Branching for 0.6.x

[Richard Hughes]

I've just branched master into PACKAGEKIT_0_5_X.

New development, large API and ABI changes will happen in master.
Distros should not ship the master branch for some weeks to allow it
to stabilize. Stable distros should keep shipping 0.5.x as this will
be supported for a year or so.

Please be aware, that the 0.5.x branch effectively makes the 0.4.x
branch obsolete, and the 0.5.x branch 100% ABI stable. 0.6.x will
remove packagekit-glib and mark packagkit-glib2 the supported GObject
library (along with the API and ABI promises). If you haven't ported
from PackageKit-glib to PackageKit-glib2 yet, you'll need to do so
before you ship 0.6.x in your product.

If you want to continue developing on the 0.5.x branch, please use:

git branch --track PACKAGEKIT_0_5_X origin/PACKAGEKIT_0_5_X
git checkout PACKAGEKIT_0_5_X

Please ensure you rebase backend changes onto master when convenient.

Thanks,

Richard.
