The standard isnan() function is defined to never throw FP exceptions
even when the argument is a "signaling" NaN. This makes isnan() more
expensive than (x != x) expression unless the compiler flag
'-fno-signaling-nans' is given.
Introduce functions isNaN(), isNonnegative(), isPositive(),
sumPositiveValues() and compareRealNumbers(), and replace isnan() in
htop's codebase with the new functions. These functions utilize
isgreater() and isgreaterequal() comparisons, which do not throw FP
exceptions on "quiet" NaNs, which htop uses extensively.
With isnan() removed, there is no need to suppress the warning
'-Wno-c11-extensions' in FreeBSD. Remove the code from 'configure.ac'.

Currently htop does not support offline CPUs and hot-swapping, e.g. via
echo 0 > /sys/devices/system/cpu/cpu2/online
Split the current single cpuCount variable into activeCPUs and
existingCPUs.

Do not read driver depended labels, just count the number of
temperatures given:
on #CPU:
platform temp = max cpu temp
CPU temps = first to last
on #CPU + 1:
platform temp = first temp
CPU temps = second to last
on #CPU / 2:
platform temp = max cpu temp
CPU temps = first to last concat first to last
(with SMT core x + cpu count is the logical core of the physical
core x)
on #CPU / 2 + 1:
platform temp = first temp
CPU temps = second to last concat second to last
(with SMT core x + cpu count is the logical core of the physical
core x)
