157086e750 Split RichString_(append|appendn|write) into wide and ascii 
RichString_writeFrom takes a top spot during performance analysis due to the
calls to mbstowcs() and iswprint().

Most of the time we know in advance that we are only going to print regular
ASCII characters.

f704baeb82 Drop unused global ProcessList memory fields 
The global ProcessList structure contains a couple of unused
fields.  'sharedMem' has never been used by any Meter, since
its not been anything other than zero in Linux /proc/meminfo
for many, many years.  The freeMem field is only used in the
usedMem calculation, so it can reside on the stack like some
other memory variables used within-calculations-only and not
exposed to the user via a Meter.

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.

enable it.
