Add ctx flag for auto-key-locate

* src/context.h (gpgme_context): Add auto_key_locate.
* src/engine-gpg.c (engine_gpg): Add auto_key_locate.
(gpg_set_engine_flags, build_argv): Handle auto_key_locate.
(gpg_release): Free auto_key_locate.
* src/gpgme.c (gpgme_release): Free auto_key_locate.
(gpgme_get_ctx_flag, gpgme_set_ctx_flag): Handle auto-key-locate.
* doc/gpgme.texi: Document auto-key-locate flag.
* tests/run-keylist.c (show_usage, main): Add --from-wkd option.

--
This enables users of GPGME to control more fine grained what
auto-key-locate does.  Especially for WKD lookups / refreshes
can this be useful.
