Nathan Scott b2a8b2426e Tweak style guide wording around single code statements 
There was wording about brace-enclosing single code statements
being 'strongly encouraged' - this isn't consistently used and
IMO it introduces unnecessary noise in otherwise neat, concise
code.

I've reworded (dropped) this section and also fixed a handful
of minor typos while reading this doc a little more carefully.

Nathan Scott 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.

Nathan Scott fee217551c Drop unneeded parameters to the ScreenManager constructor 
All calls to ScreenManager_new always pass the same first
five values, the orientation is always HORIZONTAL and the
y1 parameter is always the height of the passed-in header
struct pointer.  I think its safe to assert at this point
that no VERTICAL orientation will arrive (if it does, its
no harm in re-adding this then) - so we can remove unused
conditionals (and TODOs) based on orientation too.

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.

Christian Göttsche adf9185209 Fully support non-ascii characters in Meter-Bar 
Currently the code does not handle multi-byte characters, so length-
computations take the raw count of C characters and not the to displayed
size into account.

An example is the degree sign for temperatures.
