common: Allow a second input stream for gnupg_exec_tool_stream.

Browse source 
* common/exechelp-posix.c (do_exec): Add arg 'except' and pass to
close_all_fds.
(gnupg_spawn_process): Add arg 'except'.  Change callers to pass NULL
for it.
* common/exechelp-w32.c (gnupg_spawn_process): Add dummy arg 'except'.
* common/exechelp-w32ce.c (gnupg_spawn_process): Ditto.
* common/exectool.c (copy_buffer_do_copy): Allow NULL for SINK.
(gnupg_exec_tool_stream): Add arg 'inextra'. Change callers to pass
NULL for it.  Allow NULL for OUTPUT.

This hack is a first step to allow calling gpg for verification of
signatures.
