libmd: stop exporting _version symbols

These are reportedly likely to be specific to SSLeay's implementation
and likely not needed here. At the very least they shouldn't be used
by consumers, so let's kick them out now while we're already prepared
for a libmd soversion bump.

Fix C++ includability of crypto headers with static array sizes

C99 allows array function parameters to use the static keyword for their
sizes. This tells the compiler that the parameter will have at least the
specified size, and calling code will fail to compile if that guarantee is
not met. However, this syntax is not legal in C++.

This commit reverts r300824, which worked around the problem for
sys/sys/md5.h only, and introduces a new macro: min_size(). min_size(x) can
be used in headers as a static array size, but will still compile in C++
mode.

crypto routines: Hint minimum buffer sizes to the compiler

Use the C99 'static' keyword to hint to the compiler IVs and output digest
sizes. The keyword informs the compiler of the minimum valid size for a given
array. Obviously not every pointer can be validated (i.e., the compiler can
produce false negative but not false positive reports).

No functional change. No ABI change.
