Introduce a new in-core fork for storing copy-on-write delalloc
reservations and allocated extents that are in the process of being
written out.

[Clean up the CoW fork, should there ever be one.]

v2: fix up bmapi_read so that we can query the CoW fork, and have it
return a "hole" extent if there's no CoW fork.

What's up with all these odd commit message and tiny not really
standalone patches?

Silly me just rammed the old patch stack into the new for-next base,
with the result that the patches that still had un-merged hunks got left
in the patch stack with commit messages intact.

Dave yelled at me to fix the commit messages, so I changed the commit
messages to be the text in the brackets before the S-o-B and pushed the
mess to github.  I figured I ought to wait a day or two for more reviews
to come in before re-spamming everyone.

Sorry about the spew.
