Change allocation functions: free() to _gpgme_free(), malloc() to
_gpgme_malloc(), calloc() to _gpgme_calloc(), realloc() to
_gpgme_realloc() and strdup() to _gpgme_strdup().

--
Mostly borrowed from libassuan for custom memory handling. This changes
vasprintf.c to implement _gpgme_asprintf() and _gpgme_vasprintf() and
will always use the built-in vasprintf() even when provided by the OS.
