23bdbca2d4 Add support for glibc consumers using the new ld-linux.so.2 linker.
I can't say this was the most inspired fix, but it matches the design OK.

70bb8503aa Add provisions for variant core dump file formats, depending on the
object format of the executable being dumped.  This is the first
step toward producing ELF core dumps in the proper format.  I will
commit the code to generate the ELF core dumps Real Soon Now.  In
the meantime, ELF executables won't dump core at all.  That is
probably no less useful than dumping a.out-style core dumps as they
have done until now.

6185272d7d Initial support for using linux X servers under emulation - to use an
XFree86 server, users need to create the following links in their
/compat/linux/dev directory (assuming kernel configured with 4 VTs).

lrwxrwxrwx  1 root  wheel  7 Aug 30 22:59 tty0 -> console
lrwxrwxrwx  1 root  wheel  5 Aug 30 22:45 tty1 -> ttyv0
lrwxrwxrwx  1 root  wheel  5 Aug 30 22:45 tty2 -> ttyv1
lrwxrwxrwx  1 root  wheel  5 Aug 30 22:45 tty3 -> ttyv2
lrwxrwxrwx  1 root  wheel  5 Aug 30 22:45 tty4 -> ttyv3

VT switching is still not yet supported. Attempting to switch VT
currently will cause Xserver bus error.

5f7c8e3023 Oops, the previous fix confused Linux's sigset_t with a pointer type.
It can be integral or a struct in POSIX, so it is difficult to print,
but it is actually declared as unsigned long.  Assume that it is
unsigned integral.

67ea95908f Converted the second last instance of hzto() to tvtohz().
Fixed nearby bugs (in linux_alarm()):
- the itimer for the alarm was relative to the epoch instead of relative
  to the boot time.  This was harmless because the itimer's interval is 0.
- the seconds arg was not checked for validity before converting it to a
  possibly different value.
- printf format errors.

Improvements:
Don't use splclock().  splsoftclock() suffices.  Don't complicate things
by micro-optimizing interrupt latency.

Minor improvements:
Various micro-optimizations to exploit the specialness of the alarm itimer
and the value 0.

1d5f38ac22 This commit fixes various 64bit portability problems required for
FreeBSD/alpha.  The most significant item is to change the command
argument to ioctl functions from int to u_long.  This change brings us
inline with various other BSD versions.  Driver writers may like to
use (__FreeBSD_version == 300003) to detect this change.

The prototype FreeBSD/alpha machdep will follow in a couple of days
time.

layer does not like the null shmid_ds buffer pointer.  The emulation layer
returned an error without ever calling FreeBSD's shmctl, so the segments
were not being deleted when the reference count went to zero."

9b703b1455 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.

----
I've worked to enhance the connect() patches.

I've just tested this with the Linux JDK appletviewer on an applet
that does a lot of connects, and it works as well as during my
previous tests.

The connect() patch is now a merge between my older patch and the
OpenBSD stuff. It ensures that any async error is returned by
connect() instead of getsockopt(SOL_SOCKET, SO_ERROR) as reasonnable
systems do.

There are also minor patches to implement IPPROTO_TCP for
get/setsocktopt(). These are also tested (with Linux Apache).
----

I would appreciate any feedback regarding these changes, as they'd
be very useful in 2.2.6.
