Robert Drehmel 0357726594 - Align the function prototype of the external `crc' function with
how `crc' is actually defined.
 - Remove an unnecessary `extern' variable declaration.
Data type corrections:
 - Define a variable which contains a file byte offset value as type
   off_t as required by the `crc' function.
 - Change the type of a variable carrying a CRC checksum from `u_long'
   to `uint32_t'.
 - Substitute the wrong `extern' variable declaration of `crc_total'
   by putting a correct one in the shared header extern.h.
   `crc_total' is defined as an `uint32_t', thus fixing
   incorrect mtree checksums on big-endian LP64 machines.
