remaining TEST_MSVCRT checks

add missing native msvcrt checks to all tests,
and the ifdef TEST_MSVCRT to the sources.

probe for all our C11 Annex K functions,
but add TEST_MSVCRT checks only to those which are defined
on mscvrt currently (on my win8 machine). maybe newer ucrt.dll
versions add even more. TBD

add cross-smoking for TEST_MSVCRT via wine 32bit.  The wine libc runtime is
a bit older than the current msvcrt and has much more bugs.

add have_wine logic, where it has a broken libc: wcsncat_s, wcsrtombs_s,
asctime_s. More in later commits.
