gpg: First rough implementation of keyboxd access for key lookup.

Browse Source 
* g10/Makefile.am: Add nPth flags.
* g10/gpg.c: Include npth.h.
(gpg_deinit_default_ctrl): Deinit call-keyboxd local data.
(main): Init nPth.
* g10/keydb-private.h (struct keydb_handle_s): Add field 'kbl' and
remove the search result and the assuan context.
* g10/call-keyboxd.c (struct keyboxd_local_s): Add more fields.
(lock_datastream, unlock_datastream): New.
(gpg_keyboxd_deinit_session_data): Adjust for changed data structures.
(prepare_data_pipe): New.
(open_context): Return kbl instead of an Assuan context.  Init mutexes
etc.
(close_context): Merge into ...
(keydb_release): here.  Adjust for changed data structures.
(datastream_thread): New.
(keydb_get_keyblock): Implement datastream stuff.
(keydb_search): Ditto.

* common/asshelp.c (wait_for_sock): Add arg connect_flags.
(start_new_service): Set FDPASSING flag for the keyboxd.
--

This code as a lot of rough edges, in particular it relies on a well
behaving keyboxd.  We need to add code to shutdown the datastream
reader thread in case of errors and to properly get it up again.  We
also need to make really sure that both threads run in lockstep so
that the datastream thread is only active while we are sending a
command to the keyboxd.

We should also see whether we can depend nPth initialization on the
--use-keyboxd option to avoid any problems with nPth.

And we need to test on Windows.
