fix a/an grammar in obvious cases

update from HEAD

Add sc_pid to sockcred so that SOCK_DGRAM and LOCAL_CREDS socket option
can learn the process id of the AF_LOCAL sender.
Add compat glue for old structure.

Merge the socket locking patch:

- Socket layer becomes MP safe.
- Unix protocols become MP safe.
- Allows protocol processing interrupts to safely block on locks.
- Fixes a number of race conditions.

With much feedback from matt@ and plunky@.

Prevent overlapping calls to bind() and/or connect() on a Unix socket.

Add a new socket option for unix domain sockets: LOCAL_PEEREID, to make
it possible to get the pid, euid and egid of the process at the remote
end at the time it did bind() or connect().

Add a new libc function, getpeereid() to easily get at the euid and egid.
As a consequence, bump libc's minor number.

Document the LOCAL_PEEREID socket option in unix(4).

Based on contribution by Arne H. Juul, minor modifications by myself.

merge ktrace-lwp.

Fix the sync with head I botched.

Restore a change that made AF_LOCAL sockets block on connect(2) until
accepted.  However, this time this behavor is not the default.  Instead
it must enabled by using the LOCAL_CONNWAIT socket option on either the
connecting or accepting socket.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22364, verified by myself.

Import 4.4BSD-Lite for reference

Add flags to the unpcb, and define the "want credentials" flag.

Eliminate use of dtom() in the handing of UNIX domain sockets.  Add an
"unp_addrlen" member to the unpcb, and use it when copying the socket
name.  This eliminates that last uses of dtom() in the system.

When fstat(2)ing a file descriptor of a local communications domain socket,
fill the socket's creation time into the stat structure's st_[acm]time fields:
POSIX requires this behavior for pipe(2). N.B.: updating the st_[am]time fields
when reading/writing the pipe is neither required nor implemented, though.

add multiple inclusion protection

From trunk:
Eliminate SS_PRIV; instead, pass down a proc pointer to the usrreq methods
that need it.
Fix numerous memory leaks and bogus return values.

Make unp_addr be a pointer to the sockaddr, not to the mbuf, as with raw
sockets.

New RCS ID's, take two.  they're more aesthecially pleasant, and use 'NetBSD'

new standard, minimally intrusive ID format

Update to 4.4-Lite networking code, with a few local changes.

Remove remaining references to `UNIX'.

add rcs ids as necessary, and also clean up headers

Add consistent multiple-inclusion protection.
