* gpgmeplug.c (findCertificates): Reintroduced a free which must
have been removed after my last fix.  This avoids a memory leak
when a fingerprint was not found.  Removed the double loop
increment in the code to release the arrays.
(make_fingerprint): Removed superfluous check on retrun value of
xmalloc.
(safe_free): Removed.  Changed all callers to use a regular free
and at appropriate palces set the free pointer to NULL.  That
safe_free stuff seems to have been copied verbatim from some
Mutt example code I posted.
(storeNewCharPtr): Use xmalloc instead of an unchecked
malloc. Removed superfluous string termination.
(parseAddress): Use xmalloc instead of an unchecked malloc.
(nextAddress): Ditto.
* gpgmeplug.c:  Moved a few helper functions more to the top.
Fixed comment syntax.  Merged a copyright notice somewhere in the
middle of the file with the one at the top.
