r2518: Some long overdue changes:
- Samba4-style code in lib/registry (struct registry_key instead of REG_KEY, etc) - Use hives (like Windows has drives) instead of one root key (like a Unix FS) - usability fixes in the GTK utilities (autodetect the username, enable/disable options, etc) - fix gwsam compile - several bugfixes in the registry rpc code - do charset conversion in nt4 registry backend (This used to be commit 2762ed3b9bf1d67dd54d63e02cddbfd71ea89892)
