* g10/decrypt-data.c (decrypt_data): If OPT.UNWRAP_ENCRYPTION is set,
copy the data to the output file instead of continuing to process it.
* g10/gpg.c (enum cmd_and_opt_values): Add new value oUnwrap.
(opts): Handle oUnwrap.
(main): Likewise.
* g10/options.h (opt): Add field unwrap_encryption.
* g10/plaintext.c (handle_plaintext): Break the output file selection
functionality into ...
(get_output_file): ... this new function.

gpg_strerror.
(G10ERR_): Remove all macros and change all occurrences by their
GPG_ERR_ counterparts.

* g10/decrypt-data.c (decrypt_data): Return an error code instead of
calling BUG().
--
This code path can be triggered by fuzzing gpg and thus with some
likeness also by corrupt messages for other reasons.
* g10/decrypt-data.c (decrypt_data): Do not distinguish between a bad
MDC packer header and a bad MDC.
--
The separate diagnostic was introduced for debugging a problems. For
explaining an MDC error a single error message is easier to
understand.
* g10/cpr.c (write_status_strings): New.
(write_status_text): Replace code by a call to write_status_strings.
* g10/mainproc.c (proc_encrypted): Remove show_session_key code.
* g10/decrypt-data.c (decrypt_data): Add new show_session_key code.
--
This feature can be used to return the session key for just a part of
a file. For example to downloading just the first 32k of a huge file,
decrypting that incomplete part and while ignoring all the errors
break out the session key. The session key may then be used on the
server to decrypt the entire file without the need to have the private
key on the server.

DECRYPTION_INFO <mdc_method> <sym_algo>
Print information about the symmetric encryption algorithm and
the MDC method. This will be emitted even if the decryption
fails.
