HaikuDepot: Some work in progress to prepare "opening" packages

The idea is to parse packages for Deskbar links and offer to "open" them
once they are installed. The added functionality is not yet complete and
will eventually figure out the file system location of a package and parse
the contents. I am mainly pushing this since my git-foo is limited and
I want to push the fix for the discovered deadlock.
