and CRC tables.
* CRC.pm: New file; perl module to implement CRCs in terms of
polynomial arithmetic (verrrry slooow).
* Poly.pm: New file; perl module to do polynomial arithmetic in
the field of integers mod 2.
* t_crc.c: New file; do some sanity checks (and timing checks,
more useful when building shift-4 as well).
* Makefile.in (check-unix): Add rules for building, running
t_crc.
* crc32.c (mit_crc32_shift4): Add new function, usually not
compiled, for shift-4 implementation of CRC32.
* crc-32.h: Add (conditionalized) prototype for the shift-4
function; remove checksum_entry (it's no longer used).
* crctest.c: Removed.
* crc-test: Removed.
* crc.c: Removed.
