Chris Mason f86e8be3f8 Fix uninitialized variables, and use -O so gcc starts checking for them
Gcc only sends warnings for uninitialized variables when you compile with -O,
and there were a couple of bugs sprinkled in the code.  The biggest was the
alloc_start variable for mkfs, which can cause strange things to happen.

(thanks to Gabor Micsko for helping to find this)
