Log:
[KERNEL32]
- Rename global vars to some better names (some of the names seen in Windows 2003 asserts
and text messages).
- Add BaseDefaultPath initialization, which will be needed but the new kernel32/ldr code,
which is in turn required by the new ntdll/ldr code.
- Add some beginnings of BasepGetDllPath(), but it returns NULL anyway now so no change in
execution.
