gpg: Print a new FAILURE status after most commands.
* common/status.h (STATUS_FAILURE): New. * g10/cpr.c (write_status_failure): New. * g10/gpg.c (main): Call write_status_failure for all commands which print an error message here. * g10/call-agent.c (start_agent): Print an STATUS_ERROR if we can't set the pinentry mode. -- This status line can be used similar to the error code returned by commands send over the Assuan interface in gpgsm. We don't emit them in gpgsm because there we already have that Assuan interface to return proper error code. This change helps GPGME to return better error codes.

Postive confirmation that an operation succeeded. It is used

*** FAILURE <location> <error_code>
|

This is the counterpart to SUCCESS and used to indicate a program

failure. It is used similar to ISO-C's EXIT_FAILURE but allows to
|

convey more information, in particular an gpg-error error code.

That numerical error code may optionally have a suffix made of an

underscore and a string with an error symbol like "151011327_EOF".

A dash may be used instead of <location>.
