20fa77a948 Add ZFS compressed ARC stats to top(1)
Provides:
amount of compressed data
logical size of compressed data (how much it would have taken uncompressed)
compression ratio (logical size : total ARC size)
Overhead (space consumed for compression headers)

Example output:
ARC: 31G Total, 18G MFU, 9067M MRU, 2236K Anon, 615M Header, 2947M Other
     25G Compressed, 54G Uncompressed, 1.76:1 Ratio, 2265M Overhead

a75ca8d009 Add a toggle to display the approximate amount of swap used by each
process.  We don't *quite* pull that number out of our backside, as
the actual number is difficult to determine without modifying the VM
system to report it, but it's still useful to get an idea of what's
going on when a machine unexpectedly starts swapping.

0378533250 Silence top(1) compiler warnings
The contrib/top code is no longer maintained upstream (last pulled 16 years
ago). The K&R-style followed by the code spews -Wimplicit-int and -Wreturn-type
warnings, amongst others. This silences 131 warnings with as little modification
as possible by adding necessary return types, definitions, headers, and header
guards, and missing header includes.

The 5 warnings that remain are due to undeclared ncurses references. I didn't
include curses.h and term.h because there are several local functions and macros
that conflict with those definitions.

3f1876f2b9 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.

f3caef077b 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.

3e43795a7a Add a new option to toggle the display of the system idle process (per-CPU
idle threads).  The process is displayed by default (subject to whether or
not system processes are displayed) to preserve existing behavior.  The
system idle process can be hidden via the '-z' command line argument or the
'z' key while top is running.  When it is hidden, top more closely matches
the behavior of FreeBSD <= 4.x where idle time was not accounted to any
process.

9e69ae693d Fix brokenness in top on big-endian 32-bit systems introduced when
changing format_k2 to take a long long. Because itoa is defined as a K&R
C function, without prototyping its arguments, format_k2 passed a 64-bit

fields.

b9438a6636 The sigconv.awk script generates a sigdesc.h header file, which
contains a sigdec[] vector of structures, but the generated output is
missing braces around the initializer of each struct, which
triggers warnings in WARNS=3:

src/usr.bin/top/sigdesc.h:10: warning: missing braces around initializer
src/usr.bin/top/sigdesc.h:10: warning: (near initialization for `sigdesc[0]')

  * Fix the sigconv.awk script to generate a header with initializers
    which look better.

  * Add rules to usr.bin/top/Makefile that rebuilds a new sigconv.h
    header which matches the correct signal set from the build-time
    version of `${DESTDIR}/usr/include/signal.h' (so sigconv.h doesn't
    get stale once changes are made to the header).

  * Remove the old sigconv.h header, now that it is autoupdated at
    build time.

  * Various Makefile style fixes (the committed Makefile was kindly
    submitted by Ruslan):

    - Reorder .PATH, PROG, SRCS and CFLAGS to match style.Makefile(5)
    - Split off the generated sources (sigdesc.h top.local.h) in an
      SRCS+= line of their own.
    - Add entries to CLEANFILES near the rules that generate the
      respective files.
    - Move the explicit rule which builds top.1 after the implicit
      rules which generate its dependencies.
