userspace updates

[Resend to correct address.]
A couple fixes and one functional improvement for the userspace repo. Christian, will you take care of merging these and sending our userspace patch backlog to Avi?

Yes I'll do that
Patch 1 is already upstream, patch 2 is fine as we discussed about it on Wednesday and I test patch 3 atm.
I also updated and checked the patch out of the discussion for the unifdef issue and prepared all the test-ppc-* patches to be submitted.

hmmm maybe we can also submit the current state of translate&gdb - it's not fully featured but should work right ?
