gpg: Use gpgrt's new option parser to provide a global conf file.
* common/util.h: Remove argparse.h. * common/argparse.c: Undef GPGRT_ENABLE_ARGPARSE_MACROS. * configure.ac (GPGRT_ENABLE_ARGPARSE_MACROS): Define. * agent/gpg-agent.c: Undef GPGRT_ENABLE_ARGPARSE_MACROS and include argparse.h. Do this also for all main modules which use our option parser except for gpg. Replace calls to strusage by calls to gpgrt_strusage everywhere. * g10/gpg.c (opts): Change type to gpgrt_opt_t. Flag oOptions and oNoOptions with ARGPARSE_conffile and ARGPARSE_no_conffile. (main): Change type of pargs to gpgrt_argparse_t. Rework the option parser to make use of the new gpgrt_argparser.
This is not yet finished but a make check works. gpg has the most
complex and oldest option handling and thus this is the first
migration target. SE-Linux checks and version-ed config files are
missing and will be added later.
