md5.1: Fix the GNU mode example when using a digest file

The last example in the manpage md5(1) wants to demonstrate
GNU mode (md5sum), but uses BSD mode (md5) instead.

In GNU mode, the -c option does not compare against a hash string
passed as parameter. Instead, it expects a digest file,
as created under the name digest for /boot/loader.conf in
the example above.

sbin/md5.c: fix -q -c for BSD style versions

The BSD style commands (with names not ending in "sum") ignored the -c
options and the passed digest value when invoked with -q.

The man page stated that -q causes only the calculated digest to be
printed, but did not consider the case of both the -q and -c being
used in combination.

Since there is no warning that -c will be ignored when the -q option
is used, users night (and did) expect that the exit code would reflect
the matching of the calculated digest and the argument passed with -c.

This update implements and documents this expected behavior.

md5: Improve compatibility with coreutils and format fix

The previous changes that added support for the coreutils -c option
modified the output generated by passing -r to match that of the
coreutils versions. The difference is that coreutils separates the
hash from the file name by two blanks " " (or a blank followed by
an asterisk " *" with the -b option denoting).

While most scripts or users will not notice the difference, it might
be considered a violation of POLA and this commit reverts the change
for the non-sum programs. These will print a single blank " " as the
separator, as they die before the previous commit.

In order to still generate output that is identical to that of the
coreutils programs, this commit generates the " " or " *" separator
used by them for the -sum versions, depending on the presence of the
-b option.

sbin/md5: improve compatibility with coreutils -c option

The -c option expects a digest file in either BSD or coreutils format.

The output for matched and mismatched files is identical to that
of the coreutils version.

The review of these changes included test cases that have already
been committed for the functionality that existed before.
Another test script is added to cover the coreutils compatible
extension implemented by this patch.

This commit contains a tests/Makefile that has been cleaned up
compared to the review version, using an implicit rule to apply the
TESTBASE path at build time (and the scripts have been renamed to
have an extension of .SH instead of .sh to trigger this rule).

On Linux, there's a similar set of programs to ours, but that end in the
letters 'sum'. These act basically like FreeBSD versions run with the -r
option. Add code so that when the program ends in 'sum' you get the
linux -r behavior. This is enough to make most things that use sha*sum
work correctly (the -c / --check options, as well as the long args are
not implemented). When running with the -sum programs, ignore -t instead
of running internal speed tests and make -c an error.

Implement SHA-512 truncated (224 and 256 bits)

This implements SHA-512/256, which generates a 256 bit hash by
calculating the SHA-512 then truncating the result. A different initial
value is used, making the result different from the first 256 bits of
the SHA-512 of the same input. SHA-512 is ~50% faster than SHA-256 on
64bit platforms, so the result is a faster 256 bit hash.

The main goal of this implementation is to enable support for this
faster hashing algorithm in ZFS. The feature was introduced into ZFS
in r289422, but is disconnected because SHA-512/256 support was missing.
A further commit will enable it in ZFS.
