[COMMIT PATCH] Garbage collect py-utils.c:target_string_to_unicode.

[Pedro Alves <palves at redhat dot com>]

The strlen in this function looked suspicious, for the function
documents that STR is in the target's charset (what if it is utf-32,
etc.).

On closer inspection, nothing is calling the function, and it's been
that way ever since the function was added.

	* python/py-utils.c (target_string_to_unicode): Delete function.
	* python/python-internal.h (target_string_to_unicode): Delete
	declaration.
