Christian Göttsche 1f20c0fb3d Linux: fall back to cpuinfo on slow scaling_cur_freq read
On some AMD and Intel CPUs read()ing scaling_cur_freq is quite slow
(> 1ms). This delay accumulates for every core.
If the read on CPU 0 takes longer than 500us bail out and fall back to
reading the frequencies from /proc/cpuinfo.
Once the condition has been met, bail out early for the next couple of
scans.

Closes: #471

Christian Göttsche b5a5e83470 LED Meter: display wide characters and restore non-wide ncurses support
Print wide characters, like degree sign, properly via mvadd_wch().
Ignore attributes when returning value from RichString_getCharVal() in
non-wide ncurses mode to test against raw characters.

David Zarzycki 37e186fd66 Linux: Add SwapCached to the swap meter
According to the Linux kernel documentation, "SwapCached" tracks "memory
that once was swapped out, is swapped back in but still also is
in the swapfile (if memory is needed it doesn't need to be swapped out
AGAIN because it is already in the swapfile. This saves I/O)."

Christian Göttsche d9240999e9 Process: drop commLen
It is only used on Linux to optimize memory handling in case the command
changes to a smaller-or-equal string.

This "optimization" however causes more code bloat and maintenance cost
on string handling issues than it gains.

Christian Göttsche de645ea16c ci: enable format attributes in ncurses headers
Avoid format string issues like bfcb8ca0 by helping compilers spot such
bogus usages.

Also use LTO and O3 in the full-featured gcc job, which might trigger
