2d86428bba Let top(1) use MAXLOGNAME instead of UT_NAMESIZE.
The maximum user login length should have nothing to do with <utmp.h>.

fcaeaff4b6 Explicitly line up the CPU state labels with the calculated starting column
that takes into account the width of the largest CPU ID.  On systems with
> 10 CPUs the labels for the first 10 CPUs were not lined up properly
otherwise.

5643f3fc50 Merge r183430 from vendor/top/dist to head/contrib/top, although with
record-only mergeinfo because an automated merge is confused by the
flattening that took place:

  Move install to install-sh to prevent name-clashes.

d3bf3b9a7a system_info.cpustates isn't sparse, so a bitmask of available CPU states
is redundant (I think it's a leftover from an older implementation).

faac60c8fc - Add new 'a' switch and runtime option that allows 'top' to display process
titles extracted from argv vector instead of the real executable names.

d2d6d8d537 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.

cd660671ce Properly trim the header line too, to fix wrap-around problems that
have been noticed by running top(1) in terminals that are too narrow
(or on systems with usernames that were too long, pushing everything
too far to the right).

Note that this does *not* solve the wrap-around problem of the system
statistics, which is an entirely different matter :-/

bbf750fbff Merge the CPU and WCPU columns in a single %6.2f column, add a new 'C'
command that toggles between the two and update the ORDER_PCTCPU()
macro to sort correctly by the visible "cpu" value.

This saves 6 more columns in 80-column terminals, making things a lot
better for the COMMAND column.

32efd26355 - Add a THR column to the process listing, that shows the number of
threads a process has.  The THR column is disabled and disappears
  when 'H' is hit, because then every thread gets its own output line.

5d320d4b95 This patch merges the sort fields for both pages, so you can (for
example) view io stats while sorting by process size.  Also adds
voluntary and involuntary context-switch stats to the io page because

1b39d8a298 Fix a bug where you couldn't start top in a very small window. Now
you can start it in a small window, but it doesn't always display
anything sensible. Resizing the window does work though.

The patch is a slightly simpler one than Sheldon's in the PR.
