2.4.0 Source Import

I've imported 2.4.0 sources into our CVS tree, safely isolated on the vendor branch so theoretically nobody should see any changes until they ask for them. WE ARE NOT FOR MERGING AT THIS TIME -- it's to allow people to use CVS (esp. cvs diff and tkdiff) to examine and prepare for what's changed. We are planning to merge with whatever is reasonable, which may not be 2.4.0, around Jan 23, so consider this import only a courtesy.

If you want to see what's changed between 2.4.0test10 and 2.4.0, use

	tkdiff -rLINUS_240_TEST10 -rLINUS_240 <filename>
(or use cvs diff if you prefer).  If you want to see what a CVS
automatic merge would do, use:
	cvs update -jLINUS_240_TEST10 -jLINUS_240

on your top-of-branch tree. PLEASE DON'T COMMIT MERGED BITS unless you build a consensus it won't interfere with ongoing development or the upcoming merge.

NOTE: CVS documentation suggests using a command something like
cvs update -jlinus:yesterday -jlinus
to merge a recent import. That WON'T WORK in our tree.
