Add plist_read_from_file() to interface, update plist_from_memory()

plist_read_from_file() is a convenience function that will open a
given file, checks its size, allocates a buffer large enough to
hold the full contents, and reads from file to fill the buffer.
Then, it calls plist_from_memory() to convert the data to plist
format.
A (breaking) change had to be made so that plist_from_memory() will
also return the parsed format in its 4th argument (if non-NULL).
