svn commit: r274403 - in head/sys: compat/freebsd32 kern sys

[Adrian Chadd]

Gleb and I talked about this privately. We agreed to keep this out of
the tree for the time being, even though I have code that uses this
and does do quite a bit of traffic with it.

I'm going to use this as an excuse to finally write up a proper "wire
pages into mbufs and write them out" api for socket writes and use a
kqueue notification mechanism to complete the transactions.
