ccfb965433 Add META_MODE support.
Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.

529b5c137e Move contrib/top/top.X to contrib/top/top.xs and move
contrib/top/top.local.H to contrib/top/top.local.hs.
This fixes a build breakage when src is on a case-
insensitive file system -- we never properly create
top.x nor top.local.h. Change the makefile accordingly.

e876f6d052 Cap the percent CPU of individual threads at 100% to fix some of the
more obvious imprecision in the previous top changes.

Specifically, top uses a delta of clock_gettime() calls right after
invoking the kern.proc sysctl to fetch the process/thread list to
compute the time delta between the fetches.  However, the kern.proc
sysctl handler does not run in constant time.  It can spin on locks,
be preempted by an interrupt handler, etc.  As a result, the time
between the gathering of stats for individual processes or threads
between subsequent kern.proc handlers can vary.  If a "slow" kern.proc
run is followed by a "fast" kern.proc run, then the threads/processes
at the start of the "slow" run will have a longer time delta than the
threads/processes at the end.  If the clock_gettime() time delta is
not itself skewed by preemption, then the delta may be too short for
a given thread/process resulting in a higher percent CPU than actual.
However, there is no good way to calculate the exact amount of overage,
nor to know which threads to subtract the overage from.  Instead, just
punt and fix the definitely-wrong case of an individual thread having
more than 100% CPU.

a90539544c Rework the notion of CPU used in top. In particular, for subsequent
displays after a pause, use the difference in runtime divided by the
length of the pause as the percentage of CPU used instead of the value
calculated by the kernel.  In addition, when determing if a process or
thread is idle or not, treat any process or thread that has used any
runtime or performed any context switches during the interval as busy.

Note that the percent CPU is calculated as a double and stored in an
array to avoid recalculating the value multiple times in the comparison
method used to sort processes in the CPU display.

49e3bde165 Bump the CPU/WCPU column width by one so that it fits values from 100% up
to 999.99% CPU.  It still won't be aligned if you have a multithreaded
process using more than 1000% CPU (e.g. idle process on an idle 12-way
system), but 100% is a common case.

78210af90c Use the correct size when allocating the cmdbuf string.
cmdlengthdelta is the size of the header and we were using it to
allocate a buffer to store the command line. This would mean that
the cmdbuf could be too short. In practice this was never noticed unless
you usually run top -a. On a stock FreeBSD system you can see the
problem by running sendmail and then running top -a on a big terminal
window. In practice this doubles to size available to cmdbuf since the
header is around 65-68 bytes.

fcc3d62fa5 Rework the dynamic per-CPU stats code a bit. Always set 'statics->ncpus'
to the maximum number of CPUs to ensure that lcpustates[] array is always
allocated to the maximum size.  Previously, if top was started without
per-CPU stats it would allocate a smaller lcpustates[] array.  When
per-CPU stats were then enabled, it would overflow the array and trash
the cpustates_columns[] array causing the CPU stats to be printed in the
wrong locations.

idle threads).  The process is displayed by default (subject to whether or
not system processes are displayed) to preserve existing behavior.  The
