Ephemeral mapping (emap) implementation.  Concept is based on the idea that
activity of other threads will perform the TLB flush for the processes using
emap as a side effect.  To track that, global and per-CPU generation numbers
are used.  This idea was suggested by Andrew Doran; various improvements to
it by me.  Notes:

- For now, zero-copy on pipe is not yet enabled.
- TCP socket code would likely need more work.
- Additional UVM loaning improvements are needed.

Proposed on <tech-kern>, silence there.
Quickly reviewed by <ad>.
