561056f2e2 Grab a fix from 4.4BSD-Lite2: open(2) with O_FSYNC and MNT_SYNCHRONOUS 
had not effect.  Fix: check for either of these flags in vn_write(),
and pass IO_SYNC down if they're set.

a20d56e92e add new version of non contiguous memory code, written by chuck cranor, 
called "MACHINE_NEW_NONCONGIG".  this is required for UVM, the new VM
system (also written by chuck) that is coming soon.  adds new functions:
	vm_page_physload() -- tell the VM system about an area of memory.
	vm_physseg_find() -- returns index in vm_physmem array that this
		address is in.
and several new versions of old functions/macros defined in vm_page.h.

this is the MI portion.  sparc, and then later i386 portions to come.
all other ports need to change to this ASAP!  (alpha is already being
worked on)

cc22126721 Implement passing credentials as ancillary data on Unix domain sockets, 
enabled with the LOCAL_CREDS socket option on the listener.  Semantics are
similar to BSD/OS's:
- Creds are available with first data on SOCK_STREAM, and with every datagram
  on SOCK_DGRAM.
- It is not possible to forge credentials.

Different in that:
- Different credential data structure (ours does not rely on the format
  of internal kernel data structures, and does not pass the login name).
- We can pass creds and file descriptors at the same time (this does not
  work in BSD/OS).

Luke Mewburn <lukem@netbsd.org> gets credit for inspiring me to implement
this.  :-)

2e85747e9e From 4.4BSD-Lite2 (noted by Frank van der Linden): 
so_linger is used as an argument to tsleep(), so was stuffed with
clockticks for the TCP linger time.  However, so_linger is set directly from
l_linger if the linger time is specified, and l_linger is seconds (although
this is not currently documented anywhere).  Fix this to set the TCP
linger time in seconds, and multiply so_linger by hz when tsleep() is
called to actually perform the linger.

740f872797 New vfork(2) implementation, whith semantics matching those of the original 
3BSD vfork(2), i.e. share address space w/ parent and block parent.

Keep statistics on the total number of forks, the number of forks that
block the parent, and the number of forks that share the address space
with the parent.
