jdolecek ee882e3a09 Add port of high performance pipe implementation written by John S. Dyson 
for FreeBSD project. Besides huge speed boost compared with socketpair-based
pipes, this implementation also uses pagable kernel memory instead of mbufs.

Significant differences to FreeBSD version:
* uses uvm_loan() facility for direct write
* async/SIGIO handling correct also for sync writer, async reader
* limits settable via sysctl, amountpipekva and nbigpipes available via sysctl
* pipes are unidirectional - this is enforced on file descriptor level
	for now only, the code would be updated to take advantage of it
	eventually
* uses lockmgr(9)-based locks instead of home brew variant
* scatter-gather write is handled correctly for direct write case, data
  is transferred by PIPE_DIRECT_CHUNK bytes maximum, to avoid running out of kva

All FreeBSD/NetBSD specific code is within appropriate #ifdef, in preparation
to feed changes back to FreeBSD tree.

This pipe implementation is optional for now, add 'options NEW_PIPE'
to your kernel config to use it.
