r24667: Finally merge the registry improvements that Wilco Baan Hofman and I have
been working on for at least half a year now. Contains the following
improvements:
* proper layering (finally!) for the registry library. Distinction is
now made between 'real' backends (local, remote, wine, etc) and
the low-level hive backends (regf, creg, ldb, ...) that are only used
by the local registry backend
* tests for all important hive and registry operations
* re-enable RPC-WINREG tests (still needs more work though, as
some return values aren't checked yet)
* write support for REGF files
* dir backend now supports setting/reading values, creating keys
* support for storing security descriptors
* remove CREG backend as it was incomplete, didn't match the data model
and wasn't used at all anyway
* support for parsing ADM files as used by the policy editor (see lib/policy)
* support for parsing PREG files (format used by .POL files)
* new streaming interface for registry diffs (improves speed and memory usage
for regdiff/regpatch significantly)
... and fixes a large number of bugs in the registry code
(This used to be commit 7a1eec6358bc863dfc671c542b7185d3e39d7b5a)
