* src/gpgme.c (gpgme_set_global_flag): New. * src/gpgme.h.in (gpgme_set_global_flag): New. * src/gpgme.def, src/libgpgme.vers: Add new public function. * src/debug.c (envvar_override): New.: (_gpgme_debug_set_debug_envvar): New. (debug_init): Take ENVVAR_OVERRIDE in account. -- On Android envvars can't be used, thus we need another way to enable GPGME debugging. The new function allows this and may be used in the future to implement similar things.
