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)
