Fix compile time warning: format '%#lx' expects type 'long unsigned int', but argument 3 has type 'unsigned int'

Block.h/Block_private.h headers, since clients won't know what to
set. These are moved into runtime.c as appropriate

2) Use cmake checks for CAS builtins, instead of guessing based on GCC
#defines (which aren't set by clang and llvm-gcc anyway)

3) "#pragma mark" isn't supported by FSF gcc, so "#if 0" it out. It
should still show up in IDEs that support it

4) Fix some compiler warnings. GCC 4.3.3 seems super strict about
%p. function pointers can't be cast to void * either.

5) Avoid a warning for apple_versioning.c that "ISO C does not allow
empty files"

 - Noticed & patched by Nick Kledzik.

 - This may expose portability issues in the .S files, if so we should either
   disable them on non-Darwin, or even better make them portable.
