Log:
- Add some hacks to Cm to allow creating registry keys that finish with a backslash (this
works under NT).
- Also add a REALLY nasty hack that forces OBJ_CASE_INSENSITIVE on all Registry APIs...
this is needed because we seem to completely mess up case sensitivity otherwise and any
user-mode caller that doesn't specify that flag will fail.
- These two fixes fix all the WINE failures for the "ntdll reg" test and should
increase compatibility with some applications.
- Runtime Library Registry Wrappers Fixes and Optimizations:
- Use an array of registry paths instead of duplicating them
- Fix implenmentation of RTL_REGISTRY_HANDLE.
- Verify all Appends for failure before continuing.
- Use the strict minimum key permissions isntead of KEY_ALL_ACCESS.
- Don't use OBJ_OPENIF
- Use CAPS for \\REGISTRY\\USER (required to match a Windows quirk exposed by a WINE
test)
- Use the correct length in RtlpNtQueryValueKey
- Generic cleanups, formatting and commenting.
