Message:

Merge mainline changes (DDF refactoring)

This merge includes DDF refactoring that brought multifunctional devices
(i.e. ddf_dev_t and ddf_fun_t). Please, see ticket #295 at HelenOS
upstream Trac.

The conflicts themselves were easy to solve (merely several renamings).

Changes to USB subsystem:

• drivers uses ddf_dev_t and ddf_fun_t
• different signatures of many library functions
• several hacks around communication with parent device (now the communication is clearer and somehow what we have now is hack about other hacks)
  • will repair and clean later
• maybe added some extra debugging messages (the diff has about 240K, and I admit I have no energy to double check that)

WARNING:

• the diff is VERY long, recommended is viewing partial diffs of the merge (i.e. merges in mainline branch that lead to the parent one)
• merging with your branches might involve huge renamings, sorry, no other way is possible

BUGS:

• hub driver will not work (no function created)

GOOD NEWS:

• QEMU keyboard seems to work with QEMU 0.13 and 0.14
• we are up-to-date with mainline again
