cksum: use POSIX type uint32_t instead of u_int32_t


# 1.21 27-Apr-2020 martin

Explicitly cast the number of bytes passed to crc_buf() to size_t, as
we made sure it is positive already.
Fixes the build.


# 1.20 27-Apr-2020 riastradh

Speed up cksum word-by-word with a 15 KB table generated dynamically.

(Really we could generate the main table dynamically too.)

From anonymous.

# 1.18 04-Sep-2006 dsl

Separate out the CRC functions in a manner that actually makes them useful
for other program binaries.
Fixes build of 'config' where I added code (commented out) to use the CRC
function - but didn't comment out the #include :-(

* Kill __P()
* ANSIfy
* No parenthesis are needed around the return value


# 1.15 20-Jun-2004 jmc

Completely rework how tools/compat is done. Purge all uses/references to
_NETBSD_SOURCE as this makes cross building from older/newer versions of
NetBSD harder, not easier (and also makes the resulting tools 'different')

Wrap all required code with the inclusion of nbtool_config.h, attempt to
only use POSIX code in all places (or when reasonable test w. configure and
provide definitions: ala u_int, etc).

Reviewed by lukem. Tested on FreeBSD 4.9, Redhat Linux ES3, NetBSD 1.6.2 x86
NetBSD current (x86 and amd64) and Solaris 9.

Move UCB-licensed code from 4-clause to 3-clause licence.

# 1.11 10-Nov-2001 mycroft

Remove calculation of crc_total from here, making the routine approximately
twice as fast.


# 1.10 21-Mar-2001 atatat

Apparently changing crc() to ccrc() was bad, since mtree does a reachover.
Revert ccrc() to crc() and change local variables called crc to thecrc
instead.


# 1.9 20-Mar-2001 atatat

Rename the crc() function to ccrc() since that removes a compiler warning
when WARNS=2.

# 1.6 27-Feb-1996 cgd

what's the point of having prototypes if they're not actually _used_
in the appropriate places? include extern.h in these files, and fix
up the bugs that its inclusion uncovered.

update to the latest cksum utility from uunet. this one is posix
compliant (i think), and fixes a bogon in the old CRC calculation.
yes, that's right, the CRC's it generates are different.
