Christian Göttsche bd694c0ce6 Do not call exit(3) in signal handler

Christian Göttsche fd8c0611af Use different function on different detection method to avoid caching
Using the same function for the same library causes AC_CHECK_LIB to use
cached results.
Since we change the detection method via different or no
ncurses(5|6)-config invocation, avoid such caching by using different
functions.

- require autoconf version 2.69
  was released in 2012 and one still can configure and build on older
  systems (just not generate the configure script)
- use modern C99 compiler check
- drop obsolete checks: AC_C_CONST, AC_FUNC_CLOSEDIR_VOID, AC_FUNC_STAT
- drop AC_HEADER_STDBOOL in favor of C99 compatibility

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.

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.
