Log:
[NTDLL/LDR]
- Fix a typo in LdrQueryProcessModuleInformationEx().
- Stub LdrpEnsureLoaderLockIsHeld() for now.
- Improve LdrpRunInitializeRoutines() and enable it (just compiling, it's not in the
running path of the code yet).
- Fix an uninit var warning in ldrpe.c
- Implement LdrpClearLoadInProgress().
- Rename "ExeModule" to a more consistent LdrpImageEntry.
