* keyserver.c (keyserver_spawn): Include various pieces of information

Browse source 
about the key in the data sent to the keyserver helper.  This allows the
helper to use it in instructing a remote server which may not have any
actual OpenPGP smarts in parsing keys.

* main.h, export.c (export_pubkeys_stream, do_export_stream): Add ability
to return only the first match in an exported keyblock for keyserver
usage.  This should be replaced at some point with a more flexible
solution where each key can be armored seperately.
