b4fbe18794 Various fixes to make leased line operation more robust. On lcp_up, start
to negotiate from scratch. Make leased lines survive being put into
loopback mode. Bits and pieces and ideas taken from PRs 11238 and 21771.
Make it a module so that it can be kldloaded. Whitespace cleanup. (Can be
ignored with "cvs diff -b".)

df5e198723 Lock down the network interface queues. The queue mutex must be obtained
before adding/removing packets from the queue.  Also, the if_obytes and
if_omcasts fields should only be manipulated under protection of the mutex.

IF_ENQUEUE, IF_PREPEND, and IF_DEQUEUE perform all necessary locking on
the queue.  An IF_LOCK macro is provided, as well as the old (mutex-less)
versions of the macros in the form _IF_ENQUEUE, _IF_QFULL, for code which
needs them, but their use is discouraged.

Two new macros are introduced: IF_DRAIN() to drain a queue, and IF_HANDOFF,
which takes care of locking/enqueue, and also statistics updating/start
if necessary.

2127f26023 Examine all occurrences of sprintf(), strcat(), and str[n]cpy()
for possible buffer overflow problems. Replaced most sprintf()'s
with snprintf(); for others cases, added terminating NUL bytes where
appropriate, replaced constants like "16" with sizeof(), etc.

These changes include several bug fixes, but most changes are for
maintainability's sake. Any instance where it wasn't "immediately
obvious" that a buffer overflow could not occur was made safer.

5158516f4e In an attempt to reduce the huge number of differences between the
FreeBSD repository version of this file and the isdn4bsd version,
adopt those changes from the i4b version that make this file
BSD-version independent.  I attempted to avoid uglifying this file too
much, thus deviated a little from the i4b version (and hope they will
adopt the changes, too).

The diffs mostly concentrate on:

. #include differences between the systems
. different callout handling between FreeBSD vs. Net/OpenBSD
. interface naming (Net/OpenBSD store the ASCII name including the
  unit # in struct ifnet, FreeBSD only the name)
. use of random() in FreeBSD vs. time-based pseudo-randomization in
  Net/OpenBSD (for loopback detection ad CHAP challenges -- i
  assume at least OpenBSD could also benefit from random(), but that's
  the way i've got this file)
. interface address list elements are named a little differently
  between FreeBSD and Net/OpenBSD

I attempted to segregate those compat fixes from other code fixes and
enhancements.

227ee8a188 Eradicate the variable "time" from the kernel, using various measures.
"time" wasn't a atomic variable, so splfoo() protection were needed
around any access to it, unless you just wanted the seconds part.

Most uses of time.tv_sec now uses the new variable time_second instead.

gettime() changed to getmicrotime(0.

Remove a couple of unneeded splfoo() protections, the new getmicrotime()
is atomic, (until Bruce sets a breakpoint in it).

A couple of places needed random data, so use read_random() instead
of mucking about with time which isn't random.

Add a new nfs_curusec() function.

Mark a couple of bogosities involving the now disappeard time variable.

Update ffs_update() to avoid the weird "== &time" checks, by fixing the
one remaining call that passwd &time as args.

Change profiling in ncr.c to use ticks instead of time.  Resolution is
the same.

Add new function "tvtohz()" to avoid the bogus "splfoo(), add time, call
hzto() which subtracts time" sequences.

This will not make any of object files that LINT create change; there
might be differences with INET disabled, but hardly anything compiled
before without INET anyway.  Now the 'obvious' things will give a
proper error if compiled without inet - ipx_ip, ipfw, tcp_debug.  The
only thing that _should_ work (but can't be made to compile reasonably
easily) is sppp :-(

In sppp_chap_input:
1) in the CHAP_CHALLENGE case don't output the peer's name if it is not
what we expected (DEBUG) since it will be printed out in the course
of events anyway.
2) in the CHAP_SUCCESS case test whether the peer is required to
authenticate himself [(sp->lcp.opts & (1 << LCP_OPT_AUTH_PROTO))],
otherwise the state machine may never switch into the network state.
I saw this case against 2 different ISPs; they never bothered to
authenticate themselves to me.

In sppp_pap_input:
in the PAP_ACK case do the same as in 2) above for the same reason.

00081cc989 Major overhaul of the SyncPPP layer. Basically, this comprises now a
full implementation of the sate machine as described in RFC1661, and
provides support for plugging in various control protocols.  I needed
this to provide PPP support for the BISDN project (right now).

Unfortunatley, while the existing API was almost up to the point, i
needed one minor API change in order to decouple the this-layer-
started and this-layer-finished actions from the respective Up and
Down events of the lower layer.  This requires two additional lines in
the attach routines of all existing lower layer interface drivers that
are using syncPPP (shortcutting these actions and events).  Apart from
this, i believe i didn't change the API of all this, so everything
should plug in without too many hassles.  Please report if i broke
something in the existing drivers.

For a list of features (including new ones like dial-on-demand), and
things still to be done, please refer to the man page i'll commit asap.
