c3e6222aa5 Get rid of two and a half printf in the kernel.
Add more features to the one remaining to handle the job:
	+	signed quantity.
	#	alternate format
	-	left padding
	*	read width as next arg.
	n	numeric in (argument specified) default radix.

Fix the DDB debugger to use these.
Use vprintf in debug routine in pcvt.

The warnings from gcc may become more wrong and  intolerable because
of this.

Warning:  I have not checked the entire source for unsupported or
changed constructs, but generally belive that there are only a few.

cc3a066a29 (gulp!) reran makesyscalls..
sysv_ipc.c: add stub functions that either simply return (for the hooks
in kern_fork/kern_exit) or log() a messgae and call enosys() (for the
syscalls).  sysv_ipc.c will become "standard" in conf/files and has
#ifs for all the permutations.

8f195de8e4 Remove the #ifdef SYSVSHM etc. Always call the functions, some stubs

5d8adcbf4e Eliminate the dramatic TCP performance decrease observed for writes in
the range [210:260] by sweeping the problem under the rug.  This change
has the following effects:

1) A new MIB variable in the kern branch is defined to allow modification
of the socket buffer layer's ``wastage factor'' (which determines how
much unused-but-allocated space in mbufs and mbuf clusters is allowed
in a socket buffer).

2) The default value of the wastage factor is changed from 2 to 8.
The original value was chosen when MINCLSIZE was 7*MLEN (!), and is not
appropriate for an environment where MINCLSIZE is much less.

The real solution to this problem is to scrap both mbufs and sockbufs
and completely redesign the buffering mechanism used at both levels.

b8347dacd2 Fix the reversed source and dest args to bcopy() in the kernel space
sysctl handler (ouch!)

Add a "const" qualifier to the source of the copyin() and copyout()
functions - the other const warning in kern_sysctl.c was silenced when
copyout was declared as having a const source.. (which it is)

ca76751ddc Make pipe() return a set of bidirectional pipe fd's rather than one-way only
just like on SVR4.

This has no effect on any current programs in our source, but makes
the use of SVR4 code a little easier.  There is no code or implementation
cost in the kernel.. This two-line change merely sets the modes on the ends
of the pipes to be bidirectional.  There are no other changes.

586cc683d8 Implemented non-statistical kernel profiling. This is based on
looking at a high resolution clock for each of the following events:
function call, function return, interrupt entry, interrupt exit,
and interesting branches.  The differences between the times of
these events are added at appropriate places in a ordinary histogram
(as if very fast statistical profiling sampled the pc at those
places) so that ordinary gprof can be used to analyze the times.

gmon.h:
Histogram counters need to be 4 bytes for microsecond resolutions.
They will need to be larger for the 586 clock.
The comments were vax-centric and wrong even on vaxes.  Does anyone
disagree?

gprof4.c:
The standard gprof should support counters of all integral sizes
and the size of the counter should be in the gmon header.  This
hack will do until then.  (Use gprof4 -u to examine the results
of non-statistical profiling.)

config/*:
Non-statistical profiling is configured with `config -pp'.
`config -p' still gives ordinary profiling.

kgmon/*:
Non-statistical profiling is enabled with `kgmon -B'.  `kgmon -b'
still enables ordinary profiling (and distables non-statistical
profiling) if non-statistical profiling is configured.

02325f659c I report a problem about shmget(). (I'm using FreeBSD-2.1.0R)
int shmget(key_t key, int size, int shmflg);

If the 'key' has already existed in the system and set 'shmflg'
as '(IPC_CREAT|IPC_EXC)', then shmget() must return the error 'EEXIST'.

b5a75e1d63 Unstaticized addupc_task(). It is supposed to be called from trap().
See the comments for addupc_intr() and the NetBSD implementation.
We use dummy versions of fuswintr() and susiwintr(), so addupc_intr()
always pushes the work to trap() (this is inefficient), and trap()
calls the special i386 function addupc() instead of addupc_task().
addupc() is more efficient than addupc_intr(), so some of the lost
efficiency is recovered.  However, addupc() may be broken on plain
i386's since it doesn't check for write permission like copyout().

95d4407d25 Implemented a (sorely needed for years) double fault handler to catch stack
overflows.
It sure would be nice if there was an unmapped page between the PCB and
the stack (and that the size of the stack was configurable!). With the
way things are now, the PCB will get clobbered before the double fault
handler gets control, making somewhat of a mess of things. Despite this,
it is still fairly easy to poke around in the overflowed stack to figure
out the cause.
