wincrypt: Add to build
cmake: Allow MOSH_BUILD_MODULE on MacOS, Add CHECKMOSH_APPLETS
nmosh: Add PFFI support stubs
wx: Fix focus problem on wxGTK
wx: Font support on wxGTK
wx: Add FONTSTYLE. 2.9 does not like 0 as default.
nmosh: Use ReentrantCProcedure to make pffi calls reentrant

FIXME: This is not optimal fix. I followed Issue 198 fix but it might be
better to allocate return code into stack. (I'm not sure why we cannot
do so; maybe it would be danger on SJLJ.)
wx: Fix wx2.9 event ids

It seems wx2.9 assignes event type id dynamically.
