9c5ee42327 Implement rudumentry support for the linux TIOC[SG]ETSERIAL ioctl's.
To complete this, some extra state has to be kept somewhere so that the
B38400 flag in Linux can be correctly translated to/from either 38400,
57600 or 115200.

6bc7cb8b3f Fix the getdents() emulation, the Linux ELF libraries use this, and
this code was not quite right (linux has a readdir and getdents syscall,
with the same args. readdir only returns one entry and uses a mutant
dirent structure.  This code was also returning the mutant form for
getdents as well.  My fault for missing this before.)

e1743d02cd First attempt at FreeBSD & Linux ELF support.
Compile and link a new kernel, that will give native ELF support, and
provide the hooks for other ELF interpreters as well.

To make native ELF binaries use John Polstras elf-kit-1.0.1..
For the time being also use his ld-elf.so.1 and put it in
/usr/libexec.

The Linux emulator has been enhanced to also run ELF binaries, it
is however in its very first incarnation.
Just get some Linux ELF libs (Slackware-3.0) and put them in the
prober place (/compat/linux/...).
I've ben able to run all the Slackware-3.0 binaries I've tried
so far.
(No it won't run quake yet :)

9dfa2063d5 bt.c, aic7xxx.c:
Cleanse the SCSI subsystem of its internally defined types
	u_int32, u_int16, u_int8, int32, int16, int8.
	Use the system defined *_t types instead.

aic7xxx.c:
	Fix the reset code.
	Instead of queing up all of the SCBs that timeout during timeout
	processing, we take the first and have it champion the effort.
	Any other scbs that timeout during timeout handling are given
	another lifetime to complete in the hopes that once timeout
	handing is finished, they will complete normally.  If one of
	these SCBs times out a second time, we panic and Justin tries
	again.

	The other major change is to queue flag aborted SCBs during timeout
	handling, and "ahc_done" them all at once as soon as we have the
	controller back into a sane state.  Calling ahc_done any earlier
	will cause the SCSI subsystem to toss the command right back at
	us and the attempt to queue the command will conflict with what
	the timeout routine is trying to accomplish.

	The aic7xxx driver will now respond to bus resets initiated by
	other devices.

27253a3d9c Made the timeouts in gets() machine-independent. Use the BIOS tick
counter instead of the BIOS time call to save space.

Reworked the anti-noise timeout to avoid duplicating code.  The timeout
in the outer loop is now restarted after every noise timeout, so it is
now possible for the total timeout to be infinite; previously, the maximum
total timeout was 150000 seconds.

c50f3ecf5a Fixed restoring segment descriptors in prot_to_real(). The descriptors
must have limit 0xffff and attribute G = 0 (byte granularity) as well
as other properties that they already had (see e.g., the Intel i486
manual section 22.5).  Not restoring them broke Ctrl-Alt-Del in the
bootstrap for my ASUS P55TP4XE system, probably because the Award BIOS
does anti-tracing stuff involving inaccessible %esp's.

asm.S:
Don't use lret in prot_to_real().  This reduces the risk of using an
incompletely intialized stack segment and saves space.

d66a506616 Mega-commit for Linux emulator update.. This has been stress tested under
netscape-2.0 for Linux running all the Java stuff.  The scrollbars are now
working, at least on my machine. (whew! :-)

I'm uncomfortable with the size of this commit, but it's too
inter-dependant to easily seperate out.

The main changes:

COMPAT_LINUX is *GONE*.  Most of the code has been moved out of the i386
machine dependent section into the linux emulator itself.  The int 0x80
syscall code was almost identical to the lcall 7,0 code and a minor tweak
allows them to both be used with the same C code.  All kernels can now
just modload the lkm and it'll DTRT without having to rebuild the kernel
first.  Like IBCS2, you can statically compile it in with "options LINUX".

A pile of new syscalls implemented, including getdents(), llseek(),
readv(), writev(), msync(), personality().  The Linux-ELF libraries want
to use some of these.

linux_select() now obeys Linux semantics, ie: returns the time remaining
of the timeout value rather than leaving it the original value.

Quite a few bugs removed, including incorrect arguments being used in
syscalls..  eg:  mixups between passing the sigset as an int, vs passing
it as a pointer and doing a copyin(), missing return values, unhandled
cases, SIOC* ioctls, etc.

The build for the code has changed.  i386/conf/files now knows how
to build linux_genassym and generate linux_assym.h on the fly.

Supporting changes elsewhere in the kernel:

The user-mode signal trampoline has moved from the U area to immediately
below the top of the stack (below PS_STRINGS).  This allows the different
binary emulations to have their own signal trampoline code (which gets rid
of the hardwired syscall 103 (sigreturn on BSD, syslog on Linux)) and so
that the emulator can provide the exact "struct sigcontext *" argument to
the program's signal handlers.

The sigstack's "ss_flags" now uses SS_DISABLE and SS_ONSTACK flags, which
have the same values as the re-used SA_DISABLE and SA_ONSTACK which are
intended for sigaction only.  This enables the support of a SA_RESETHAND
flag to sigaction to implement the gross SYSV and Linux SA_ONESHOT signal
semantics where the signal handler is reset when it's triggered.

makesyscalls.sh no longer appends the struct sysentvec on the end of the
generated init_sysent.c code.  It's a lot saner to have it in a seperate
file rather than trying to update the structure inside the awk script. :-)

At exec time, the dozen bytes or so of signal trampoline code are copied
to the top of the user's stack, rather than obtaining the trampoline code
the old way by getting a clone of the parent's user area.  This allows
Linux and native binaries to freely exec each other without getting
trampolines mixed up.

9d2baf5cdf Update the Connectix QuickCam driver to match my current work.
- split driver into FreeBSD specific and camera specific portions
  (qcamio.c can run in user mode, with a Linux "driver top" etc,
   and qcam.c should be trivial to port to NetBSD and BSDI.)
- support for 4bppand bidirectional transfers working better
- start of interleaved data-transfers byte-stream decodes (some of this
  stuff has been pulled out for the moment to make it easier to debug)

At this point, anyone who wants to port it to other platforms should feel
free to do so.  Please feed changes directly back to me so that I can produce
a unified distribution.
