Make CmiScanKeyForValue and CmiScanForSubKey simple wrappers around the newer CmpFindSubKeyByName and CmpFindValueByName routines. - Allow cmlib to support HINIT_FILE flag for HvInitializeHive. This means the kernel doesn't need to create a section for the hive, then call HvInitializeHive with HINIT_MEMORY anymore, and can simply send the file handle. I wrote a sneaky little hack in cmlib which actually ends up doing the same idea, albeit not by using a section, making it portable. - Fix a serious bug in CmpFindSubKeyInLeaf affected by our lack of alphabetically-sorted cells; the linear search I hacked was slightly broken. - Remove the need to hold a LogFileName in the hive structure, since we generate it dynamically now.
