Christian Göttsche 58a59c11f4 linux: drop dead process field column DIRTY 
The field for dirty pages in /proc/[pid]/statm is always 0 since Linux
2.6 (see man:proc(5)).

Nathan Scott 1bd95983b2 Add columns for process autogroup identifier and nice value 
Adds AGRP (autogroup) and ANI (autogroup nice) columns that
report the information from /proc/PID/autogroup, as well as
handlers for '{' and '}' to change the autogroup nice value.

This is guarded by /proc/sys/kernel/sched_autogroup_enabled
such that sampling and/or changing values wont be attempted
unless the kernel feature is enabled.

Fixes: #720

Christian Göttsche 323d7e73aa Linux: update IO fields 
- fix header width of IO_READ_RATE

- save data in bytes (not kilobytes) to better compute rate

- fix rate data: multiply with 1000 to compensate time difference in
  milliseconds

- rename unit less variable now into realtimeMs

- use Process_printBytes(..., data * pageSize, ...) instead of
  Process_printKBytes(..., data * pageSizeKB, ...) to avoid wrapper

Christian Göttsche 9a8221568a Rework TTY column 
* Rename internal identifier from TTY_NR to just TTY
* Unify column header on platforms
* Use devname(3) on BSD derivate to show the actual terminal,
  simplifies current FreeBSD implementation.
* Use 'unsigned long int' as id type, to fit dev_t on Linux.

Only on Solaris the terminal path is not yet resolved.

Christian Göttsche fdaa15bd8d Linux: overhaul io process fields 
- avoid UBSAN conversions
- print N/A on no data (i.e. as unprivileged user)
- fix rate calculation to show bytes (instead of a thousandth)
- print bytes as human number (i.e. 8MB) instead of 8388608
- stabilize sorting by adjusting NAN values to very tiny negative number

Christian Göttsche 293c16e22d Only initialize and gather delay accounting data if a related column is enabled 
Avoid creating and communicating over a netlink socket by default, which
triggers cap_net_admin checks as root.

Nathan Scott a3db2da4a7 Cleanup initialization of jiffies on the Linux platform 
Small cleanups - add error handling, remove a local static
variable and refactor LinuxProcess_adjustTime (also rename
it, as its in LinuxProcessList.c not LinuxProcess.c) - and
while there, move the related 'btime' global variable into
LinuxProcessList.c so it can be made static.

Nathan Scott 75e9f9a8d9 Cull the definitions of pageSize and pageSizeKB from CRT.c 
By storing the per-process m_resident and m_virt values in the form
htop wants to display them in (KB, not pages), we no longer need to
have definitions of pageSize and pageSizeKB in the common CRT code.

These variables were never really CRT (i.e. display) related in the
first place.  It turns out the darwin platform code doesn't need to
use these at all (the process values are extracted from the kernel
in bytes not pages) and the other platforms can each use their own
local pagesize variables, in more appropriate locations.

Some platforms were actually already doing this, so this change is
removing duplication of logic and variables there.

Christian Göttsche 9b31ee5b63 Drop taskstats conditional 
taskstats is only checked on runtime if the column RCHAR, WCHAR, SYSCR,
SYSCW, RBYTES, WBYTES, CNCLWB, IO_READ_RATE, IO_WRITE_RATE or IO_RATE is
selected.

taskstats is currently enabled by default.

Drop the taskstats configuration switch, to reduce the maintenance cost.

Christian Göttsche c88c80e3bd Drop cgroup conditional 
cgroup is only checked on runtime if the column CGROUP is selected.

cgroup is currently disabled by default, but most distributions do
enable it.

Drop the cgroup configuration switch, to reduce the maintenance cost.
