[PATCH] SMB user/password caching across shares

[Nielsen <nielsen memberwebs com>]

This patch develops the SMB password caching further, as discussed 
earlier on this list:

- Cache password for the entire server in addition to per share.
- If no password is cached for a share, look for the server cached
  password.
- Fix threading (had no lock) problems on the cache reaping
  callback.
- Keep an internal password cache in additon to gnome keyring.
- Merge default user and password cache.

Any and all comments welcome. Is this a feature or a bug fix? I guess 
that decides whether it gets into GNOME 2.10.

Cheers,
Nate
