Subject: [PATCHSET 3/9] fuse2fs: clean up operation startup

Hi all,

Reduce the amount of boilerplate in fuse2fs by creating helper functions
to start and finish a file operation instead of open-coding the logic
all over the place.  This also fixes a couple of theoretical races.

If you're going to start using this code, I strongly recommend pulling
from my git trees, which are linked below.

Comments and questions are, as always, welcome.
