inclusion of VJ compression into sppp.
Now, instead of the need to include this and that and everything plus
the kitchensink in each of those drivers, struct sppp uses struct
slcompress as an opaque structure only referenced by a pointer. The
actual structure is then malloced at initialization time.
While i was at it, also fixed a bug where received VJ packets would only
be recognized if INET6 was defined.
(1) Don't attempt aquire the non-recursive lock sio_lock recursively.
Doing so caused unbounded recursion in some setups. E.g., if DDB,
BREAK_TO_DEBUGGER and WITNESS are configured; if the debugger is
entered using a break, then WITNESS will actually detect the invalid
recursion and will add to it attempting to print a message about it.
(2) Don't use sio_lock before it has been initialized. The old check
(sio_inited != 0) didn't work when sio_inited was boolean because
sio_inited was set too early, and became just wrong when sio_inited
was changed to a tri-state variable in rev.1.348.

time from the PPP packets sent. This effectively merges rev 1.2 of
the old i4b_ispppsubr.c, with the exception that i eventually ended up
in debugging and fixing it so the idle time is now really
detected. ;-) (The version in i4b simply doesn't work right since it
still accounts for incoming LCP echo packets which it is supposed to
ignore for idle time considerations...)

sppp_parms that are needed for the SPPPIO[GS]DEFS ioctl commands.
This allows it to keep struct sppp inside #ifdef _KERNEL (where it
belongs), and prevents userland programs that wish to include
<net/if_sppp.h> from including the earth, the hell, and the universe
before the are able to resolve all the kernel-internal stuff that's in
struct sppp.

This (effectively) merges rev 1.36 of i4b's old if_spppsubr.c, albeit
in a slightly different manner (we export the timer in millisecond
values as exposed to tick values from/to userland).

This is the logical merge of rev 1.32 of i4b's old if_spppsubr.c (which
was based on PR misc/11767), plus (i4b) rev 1.6 of i4b's if_ispppsubr.c,
albeit with numerous stylistic and cosmetic changes.

Character-Map. RFC 1662 demands it for the sake of async to sync
PPP protocol converters (like Win9* :).
This merges rev 1.26/1.27 of the old i4b sppp changes.
route to the destination twice. Now that brian has fixed route.c to no
longer accept this second route, this long-standing nuisance became a
showstopper bug for sppp users.
In retrospect, this is the same fix as the one in rev 1.78 of if_sl.c;
most likely the original version of sppp has been cloned from SLIP. ;-)

see people trip over it. Do not set the FIFO trigger to just before it
would otherwise overflow. Give it a little more slop so characters aren't
lost if the interrupt is delayed by other system activities.

- Temporary fix a bug of Intel ACPI CA core code.
- Add OS layer ACPI mutex support. This can be disabled by
specifying option ACPI_NO_SEMAPHORES.
- Add ACPI threading support. Now that we have a dedicate taskqueue for
ACPI tasks and more ACPI task threads can be created by specifying option
ACPI_MAX_THREADS.
- Change acpi_EvaluateIntoBuffer() behavior slightly to reuse given
caller's buffer unless AE_BUFFER_OVERFLOW occurs. Also CM battery's
evaluations were changed to use acpi_EvaluateIntoBuffer().
- Add new utility function acpi_ConvertBufferToInteger().
- Add simple locking for CM battery and temperature updating.
- Fix a minor problem on EC locking.
- Make the thermal zone polling rate to be changeable.
- Change minor things on AcpiOsSignal(); in ACPI_SIGNAL_FATAL case,
entering Debugger is easier to investigate the problem rather than panic.
