r18981: * cleanup some vestiges of old cli_reg.c code and mark some TODO

  items in cac_winreg.c
* Get 'net rpc registry enumerate' to list values again
* Fix winreg.idl QueryInfoKey().  The max_subkeysize is the
  max_classlen (we previously had this correct in Samba3")
* fix valgrind error about uninitialized memory and use-before-set
  on size value inmemset() call
* Fix key enumeration in 'net rpc registry enumerate'
* regenerate gen_dir files based on local pidl patches

Please note that the generated ndr files are from my local
copy of pidl.  If you need to regenerate, please apply the
patch that I posted to the samba-technical list earlier today.
