5bb4f73817 The death of `options NODUMP'. Now the dump area can be dynamically
configured (and unconfigured) on the fly.  A sysctl(3) MIB variable is
provided to inspect and modify the dump device setting.

b5e8ce9f12 Add and move declarations to fix all of the warnings from `gcc -Wimplicit'
(except in netccitt, netiso and netns) and most of the warnings from
`gcc -Wnested-externs'.  Fix all the bugs found.  There were no serious
ones.

e6373c9ec0 Implement maxprocperuid and maxfilesperproc. They are tunable
via sysctl(8). The initial value of maxprocperuid is maxproc-1,
that of maxfilesperproc is maxfiles (untill maxfile will disappear)

Now it is at least possible to prohibit one user opening maxfiles

to be accessed if a process blocks when it is being run down.

f81fcd410f Fix bug in sysctl_string so that when a string has a length that is to
short, it gets filled uop to its length. This matches the getdomainname
and gethostname manual pages.
(getbootfile also uses this function and I think it should have the same
behaviour)

This also fixes a bug with keyinit where the seed was not saved in
/etc/skeykeys. So S/Key should be fully functional again.

3f31c649d1 Redo Kernel NTP PLL support, kernel side.
This code is mostly taken from the 1.1 port (which was in turn taken from
Dave Mills's kern.tar.Z example).  A few significant differences:

1) ntp_gettime() is now a MIB variable rather than a system call.  A few
fiddles are done in libc to make it behave the same.

2) mono_time does not participate in the PLL adjustments.

3) A new interface has been defined (in <machine/clock.h>) for doing
possibly machine-dependent things around the time of the clock update.
This is used in Pentium kernels to disable interrupts, set `time', and
reset the CPU cycle counter as quickly as possible to avoid jitter in
microtime().  Measurements show an apparent resolution of a bit more than
8.14usec, which is reasonable given system-call overhead.

501c23938c Define new MIB variable, hw.floatingpoint, which is true if FP hardware
is present, and false if an emulator is being used.

f23b4c91c4 Fix up some sloppy coding practices:
- Delete redundant declarations.
- Add -Wredundant-declarations to Makefile.i386 so they don't come back.
- Delete sloppy COMMON-style declarations of uninitialized data in
  header files.
- Add a few prototypes.
- Clean up warnings resulting from the above.

NB: ioconf.c will still generate a redundant-declaration warning, which
is unavoidable unless somebody volunteers to make `config' smarter.

9ae159169a Make it easier for programs to figure out what revision of FreeBSD they
are running under.  Here's how to bootstrap (order is important):

1) Re-compile gcc (just the driver is all you need).
2) Re-compile libc.
3) Re-compile your kernel.  Reboot.
4) cd /usr/src/include; make install

You can now detect the compilation environment with the following code:

#if !defined(__FreeBSD__)
#define __FreeBSD_version 199401
#elif __FreeBSD__ == 1
#define __FreeBSD_version 199405
#else
#include <osreldate.h>
#endif

You can determine the run-time environment by calling the new C library
function getosreldate(), or by examining the MIB variable kern.osreldate.

For the time being, the release date is defined as 199409, which we have
already established as our target.
