fs: Add uoff_t
In a recent commit, I inadvertently changed a comparison from being an
unsigned comparison (on 64-bit systems) to being a signed comparison
(which it had always been on 32-bit systems). This led to a sporadic
fstests failure.
To make sure this comparison is always unsigned, introduce a new type,
uoff_t which is the unsigned version of loff_t. Generally file sizes
are restricted to being a signed integer, but in these two places it is
convenient to pass -1 to indicate "up to the end of the file".
