code is all conditionalized on __HAVE_TIMECOUNTER, and not
enabled on any platforms.
adjtime(2) support exists, courtesy of nordin@, sysctl(2) support
and a concept of quality for each time source attached exists.
High quality time sources exists for PIIX4 ACPI timer as well as
some AMD power management chips. This will have to be redone
once we actually add ACPI support (at that time we need to use
the ACPI interfaces to get at these clocks).

fetching via sysctl. deraadt@ tholo@ drahn@ millert@ ok

translates a cpu_info structure into a human-readable cpu number.

Add trivial support for passing a NULL pointer for the argv buffer;
currently just returns ARG_MAX for KERN_PROC_ARGV and KERN_PROC_ENV.

Introduce the cpu_info structure, p_cpu field in struct proc and global
scheduling context and various changed code to deal with this. At the
moment no architecture uses this stuff yet, but it will allow us slow and
controlled migration to the new APIs.
All new code is ifdef:ed out.

remove alpha specific definition of ncpus.
OK (and tested on alpha) deraadt@

update cpu even with 100 -> 100 setperf changes, in case saved value
has gotten out of sync. from grange@ ok deraadt@ grange@

an interrupt safe thread.
use this as the new backend for mbpool and mclpool, eliminating the mb_map.
introduce a sysctl kern.maxclusters which controls the limit of clusters
allocated.
testing by many people, works everywhere but m68k. ok deraadt@
this essentially deprecates the NMBCLUSTERS option, don't use it.
this should reduce pressure on the kmem_map and the uvm reserve of static
map entries.

separate exec format from emulation. consistent naming of freebsd emuls.
not much in the way of functional changes yet.
testing and ok deraadt@ and others along the way.

the sysctl_doproc() switch so it does not match the default case
(EINVAL). deraadt@ OK.

have ps and friends be independent of changes in struct proc et al
in the kernel. OK deraadt@

convert longrun support to use new sysctls.
add enhanced speedstep support, based on code by Michael Eriksson.

Closes PR 3571 as per on icb.

add e_flags to struct emul. this stores on/off and native flags.
check for emul enabled in check_exec(). gather all the emuls into a
emulsw so a sysctl can find them. create sysctl. move maxhdrsiz calcualation
into init_main so it cleans up sys_execve codepath. teach sysctl utility
to grok kern.emul hierarchy.
requested and ok deraadt@ some comments from mickey@

argument. old cred only calls user suser_ucred. this will allow future
work to more flexibly implement the idea of a root process. looks like
something i saw in freebsd, but a little different.
use of suser_ucred vs suser in file system code should be looked at again,
for the moment semantics remain unchanged.

new node hw.sensors; information from the sensors can be obtained
via hw.sensors.n, where n is a sensor number. All values are read only
for now. Documentation and back-end drivers are comming.

o Avoid taking the address of an array when we just want a pointer
o Use &array[1] not array + 1

Instead of allocating a static amount of memory for the data
structures via valloc() in allocsys(), allocate things dynamically
using pool(9) when possible and malloc(9) when not. The various
members of struct seminfo and struct shminfo are in kern.seminfo
and kern.shminfo respectively (not all members of kern.seminfo are
changable).
The data structures used still leave something to be desired but
things are not made worse in that respect by this commit.
