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
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.
strcasestr(3) is a GNU extension and when compiling freebsd/Platform.c
on kfreebsd for Debian <string.h> is included before we define
_GNU_SOURCE, so the function is not available.

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)."
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.

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
additional warnings on advanced inlining, like
3695cbd5d8 and
ad3acfc847
Partially revert 4b14ab9789
ColorPair(Black,Black) is not actually black on black, but due to
adjustments in CRT_setColors() black on default-background-color.
Thanks to V for reporting.
mvwprintw takes a format string as its fourth argument, and title is
user-controlled. This results in e.g. crashing when trying to trace a
process with a format specifier in its command line.
