patch

There are already functions to create surfaces for filenames and streams; that
attached patch adds the API to do the same for file descriptor.

While it is true that this can already be accomplished by using the stream
functions with a custom write function, that's leading to code duplication, and
is not as convenient as a simple API call. Also, cairo internally already has
all the code in cairo-output-stream.c to handle this; all it needs is be
exposed.
