[COMMIT PATCH 1/2] savestring: Rename parameter 'size' to 'len'.

[Pedro Alves <palves@redhat.com>]

It's better to avoid needless confusion, and call a string's length,
length, instead of size, which is usually used to refer to sizeof of
the string (len+1):

	size_t len = strlen (str);
	size_t size = sizeof (str);

Tested on x86_64 Fedora 17.
