dired-create-directory with arbitrary depth

[Juri Linkov]

I propose to remove a restriction that `dired-create-directory' can create
only one immediate subdirectory.  The patch below keeps the old behavior
for creating an immediate subdirectory but also allows creating
subdirectories with an arbitrary depth.  It searches for the topmost
nonexistent parent directory and uses it to add a dired entry.  It also
calls `make-directory' with the `parents' arguments to create all parent
directories:
