    - To cleanup the pgp/smime code and prepare for other backends. · c901be35

     - Support gpg-agent by not asking for a passphrase
     - autconf cleanups.
    
    This is just a start and probably we need a couple of other things to
    do. One drawback is that the help menu does always list all crypto
    realted stuff even when configured for no crypto at all.  Same goes
    for the configure options but I consider thsi a feature: It allows to
    use the same .muttrc for different versions of mutt - at least during
    development, this is an advantage.  This all might be fixed but
    requires some changes to the configuration system.
    
    Note, the use of the WithCrypto macro - it enables the compiler to do
    dead-code-elimination depending on the configured backend.  This is
    better readable than all the nested ifdefs.  I did some short tests
    and it seems to work, althoug mutt's size does not change largely when
    compiled w/o crypto.
    
    cryptglue.c is new as a warpper to all crypto calls; some are still in
    crypt.c but they should eventually also be wrapped.  We don't use
    function pointers to keep a path to use dlopen or runtime configured
    backends.  crypt.h is also new and replaces pgp.h and smime.h in most
    files (except for the backend).

    	* crypt.c (crypt_valid_passphrase): Detect gpg-agent and don't ask
    	for the passphrase.
    	* pgp.c (pgp_decrypt_part, pgp_application_pgp_handler)
    	(pgp_sign_message, pgp_encrypt_message)
    	(pgp_traditional_encryptsign): Make sure that we never ever send
    	the passphrase if the gpg-agent has been detected.  Likewise.
    
    	* acconfig.h: Removed all remaining stuff as AC_TEMPLATEs to
    	configure.in. BTW, we should consider to rename configure.in to
    	configure.ac.
