This source patchset addresses the following:
Library Extension (readproc)
. added PROC_EDITCGRPCVT flag
. added an internal (static) fill_cgroup_cvt function:
. reads AND parses /proc/#/cgroup
. returns result as a single string in a single vector
. thus no changes to proc_t structure or free memory logic
Program Enhancements (top)
. removed parse_cgroup logic in favor of libproc
. eliminated cgroup sort recurring overhead
. converted WCHAN field to variable width
. generalized variable width field logic in task_show
. real-time notation under P col more distinctive as 'rt'
Program Cosmetic (top)
. CGROUP now known as CGROUPS (plural)
. moved jan's attribution from top.c to 'Notes' in top.h
. numerous comments tweaked
Document Enhancements (top)
. documented CGROUPS field (required renumbering all fields)
. adapted narratives for the 3 current variable width fields
. expanded real-time scheduling notes, 'RT' now shown as 'rt'

Support long options, use program_invocation_short_name, print
version up on request, new giga & tera byte sizes switches, exit
when numeric arguments has garbage... and for rest see the diff.

This source patch addresses the following:
Conceivable Buglets Avoided
. added sanity checks for previous assumptions re: pid size, num cpus
. changed response for rcfile errors to fatal, vs. silent default
Enhancements
. reorganized WIN_t struct for reduced padding and better readability
. generalized code for multiple var-width cols (divorced from pflags)
. absorbed jan gorig's cgroup patch, with attribution
Cosmetic

The documentation portion of the patch addresses the following:
README.top
. corrected a minor typo
. updated to reflect current patch level
top.1
. fixed potentially misinterpreted Me/ME strings
. added '.Bd -literal' directives for indented fixed-width font
. some comments changed from \# to .\" to avoid man2html problems
The source portion of the patch addresses the following:
Buglets
. header/task output length now consistent
. fixed 2 obscure horizontal scrolling bugs
. fixed potential bug regarding 'help' and 'current' window
. messages and prompts are now also sensitive to terminal width
. normalized buffer names/sizes now accommodate any SCREENMAX changes
Features
. made %CPU and 'i' mode handling more efficient
. for input the Up/Dn arrows keys act as alternatives to Ins/Del keys
. an optional USE_X_COLHDR define eliminates ALL 'x' toggle overhead
. an optional ZAP_SUSEONLY define was added for Werner's modifications
Cosmetic
. defines and format for optional end-of-job reports standardized

Having one constructor depend on another means if the order
is reversed you get a different result.

Read the time of system boot from /proc/stat (entry: btime) instead
of computing it as the difference between the current time and the
uptime. This is the only way to get a consistent result which won't
possibly change from one run to the next.
The problems with the original code were:
* Both the current time and the uptime are rounded down to the second,
but the system doesn't boot on an integer second value so they do not
tick at the same moment. Thus, the rounding errors can cause a one
second difference from one run to the next.
* We can't read the uptime and the current time at the exact same moment
anyway, so the time difference we compute is bound to be inaccurate.
