s3: Wrap calls to the s3 registry API.

To use Samba 4's libregistry in the registry editor, some
compatibility issues with Samba 3 need to be addressed.
"struct registry_key" is defined differently in source3 and
source4, and so this wrapper is used to isolate conflicting
types and avoid headaches compiling the code.

regedit: Setup a test tree view of HKLM.

Expand on the former test by allowing the user to walk HKLM
with the tree view. Subkeys are loaded dynamically in memory
as the user walks the hierarchy with tree_node_load_children().

One issue with this at the moment is detecting if the
in-memory copy of the hierarchy is out of date.

TODO: figure out when to reload out of date portions of the
hierarchy (probably by checking last_modified_time).
