There have been a number of complaints from a number of sources that names

like Malloc, Realloc and especially Free conflict with already existing names

the names of the OpenSSL memory allocation macros to something that has a
better chance of being unique, like prepending them with OPENSSL_.

This change includes all the name changes needed throughout all C files.
