* src/sig-check.c
** check_key_sigs: If we use CDK_KEYDB_HD other keys can't be found.

* src/keydb.c
** Make the code reentrant and much simpler. Remove all overhead.

* src/stream.c
** Make the walk_xxx functions easier and improve them to fix the
problems we have in sign.c

* add doc headers to all external functions so we can use 'gdoc'.

* grep the code for all 'fixme/todo's and replace them with real code.

* add ldap keyserver support (?)
