RFC: core VFD changes

Hi all,

This RFC discusses some changes to the core VFD that will appear in 1.8.13. Basically, it's a mechanism that tracks writes so when you open an existing file and modify a few bytes, only the changes are written out on file close. The current behavior is to write out the entire file, which is wasteful in some use cases. Note that write tracking is turned off by default.

This feature is complete (it was created for a customer a while back) but there is still time to make changes if anyone has any comments.
