warning.
* sign.c (clearsign_file): Fix bug that prevents proper warning message
from appearing when clearsigning in --pgp2 mode with a non-v3 RSA key.
* main.h, misc.c (compliance_option_string, compliance_string,
compliance_failure), sign.c (sign_file, clearsign_file), encode.c
(encode_crypt, write_pubkey_enc_from_list): New functions to put the "this
message may not be usable...." warning in one place.
* options.h, g10.c (main): Part two of the simplification. Use a single
enum to indicate what we are compliant to (1991, 2440, PGPx, etc.)
* misc.c (checksum_u16_nobug): Removed.
(checksum_u16): Removed the bug emulation.
(checksum_mpi): Ditto.
(checksum_mpi_counted_nbits): Removed and replaced all calls
with checksum_mpi.
* parse-packet.c (read_protected_v3_mpi): New.
(parse_key): Use it here to store it as an opaque MPI.
* seckey-cert.c (do_check): Changed the v3 unprotection to the new
why to store these keys.
(protect_secret_key): Likewise.
* build-packet.c (do_secret_key): And changed the writing.
restarting gpg. This is Debian bug 124219, though their supplied patch
will not do the right thing.
* main.h, tdbio.c (tdbio_set_dbname), misc.c (removed check_permissions),
keydb.c (keydb_add_resource), g10.c (main, check_permissions): Significant
reworking of the permission check mechanism. The new behavior is to check
everything in the homedir by checking the homedir itself. If the user
wants to put (possibly shared) keyrings outside the homedir, they are not
checked. The options file and any extension files are checked wherever
they are, as well as their enclosing directories. This is Debian bug
147760.
