Save XML files into a memory buffer rather than directly into a file

Browse source 
This introduces a "struct membuffer" abstraction that you can write
things into, and makes the XML saving code write to the memory buffer
rather than a file.

The UDDF export already really wanted this: it used to write to a file,
only to then read that file back into memory, delete the file, and then
*rewrite* the file after doing the magic xslt transform.

But the longer-term reason for this is that I want to try to write other
formats, and I want to try to share most helpers.  And those other
formats will need this memory buffer model.
