eliminate inclusion loops in safe_mem_lib.h and safe_str_lib.h

sounds good. c++ is also a good check for finding such recursion errors.

Note that I had to change the includes a bit for windows support.
Currently I'm fine with safe_lib.h being included by the 2 others, and vice versa.
Just doxygen needs to get 2 more cpp defines to stop worrying.

Done with 234f3b0

234f3b0 doesn't get rid of the inclusion loops. safe_str_lib.h still includes safe_lib.h. I envision the fix is to remove all types from safe_lib.h so that safe_str_lib.h doesn't need to depend on it at all. safe_lib.h is just the umbrella "include all" header.
