Clean up inode code:
- Change inode_byte_to_sector() to insist that its argument be a valid
file offset, and change file_read_at() and file_write_at() to always
call it with one.
- Change inode_create() to just create the inode on disk without
returning a struct inode. Change return value to bool. Update
callers to understand.
- Integrate alloc_inode() into its one remaining caller.
- Break inode deallocation into new static function deallocate_inode().
Change bitmap code from using (start...end) to indicate ranges to
using (start, cnt). Update all callers. Other minor internal bitmap

the indirect effect that we don't need to strip debug symbols from
