to libgcrypt functions, using shared error codes from libgpg-error,
replacing the old functions we used to have in ../util by those in
../jnlib and ../common, renaming the malloc functions and a couple of
types. Note, that not all changes are listed below becuause they are
too similar and done at far too many places. As of today the code
builds using the current libgcrypt from CVS but it is very unlikely
that it actually works.
decryption failed error if a MDC does not verify. Warn if a MDC is not
present (can disable via --no-mdc-warning).
* exec.c (exec_write), g10.c (main), keyserver.c (keyserver_spawn): Use
new DISABLE_KEYSERVER_PATH rather than FIXED_EXEC_PATH.
keyserver.c (keyserver_spawn): If the user does not use "exec-path",
completely replace $PATH with GNUPG_LIBEXECDIR before calling the
keyserver helper. If the user does use "exec-path", append
GNUPG_LIBEXECDIR after the specified path.
FIXED_PHOTO_VIEWER and DISABLE_PHOTO_VIEWER.
* mainproc.c (check_sig_and_print): Use --show-photos to show photos when
verifying a sig made by a key with a photo.
* keyserver.c (parse_keyserver_uri): Properly parse a URI with no :port
section and an empty file path, but with a terminating '/'.
(keyserver_work): Honor DISABLE_KEYSERVER_HELPERS.
* hkp.c (hkp_ask_import): Display keyserver URI as a URI, but only if
verbose.
* exec.c, g10.c: USE_EXEC_PATH -> FIXED_EXEC_PATH
