Make the struct lfs 512 bytes long on 32bit machines whose compiler doesn't

Browse Source 
align 32bit integers. Use explicit sized typing at some other places.

XXX This still won't fix lfs for 64bit machines, as we have some
assumptions about sizeof(pointer)=sizeof(u_int32_t) in here, and (if I
looked right) a misaligned u_int64_t. The right fix (to cite cgd) will
be to seperate on-disk-representation from in-core, but I don't have
the time (at the moment) to do this.
