regedit: Merge getRegClass() and getRegKeyName() to form parseKeyName().
Keep track of the full registry path (including the root key) in currentKeyName. This makes the error messages more informative. Reduce the number of global variables used by openKey() & co. Only use one variable, currentKeyHandle, to indicate whether a key is currently open or not.
