* Use MemAvailable info from Linux 3.14+ where available
* Thanks to Chris Cheney for reporting and Tomas Wido for an initial implementation
Closes#281Closes#385
Use similar calculation than procps.
Show AvailableMemory in text mode.
Use total minus available memory instead of manually computed used-
memory as fraction part in bar mode (if available).
The State struct holds a pointer to the main process panel.
Use the distinct MainPanel type, to improve maintainability regrading
its usage.
This avoids usages of down-casts from Panel to MainPanel, only up-casts
from MainPanel to Panel are now required.
Unavailable values are returned as "n/a" from lsb_release, skip these.
$ lsb_release -a
LSB Version: 1.4
Distributor ID: Arch
Description: Arch Linux
Release: rolling
Codename: n/a
As SYSCONFDIR is a compile time string literal, use compile time string
concatenation instead of a runtime one.
Also drop related TODO, cause we indeed using the correct way of getting
$sysconfdir from autoconf
If the last process entry is selected and the process dies, stay at the
end of the list and do not jump to the start.
Also if the last entry is selected keep, after rebuilding the process
list due to a new scan, the last entry selected.
At start, SysArchMeter calls the uname function to obtain the kernel
version and architecture. If available, the distro version is obtained
by calling lsb_release. The obtained values are stored in static
variables and used when updating the meter.

SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior linux/LinuxProcessList.c:314:23 in
- avoid UBSAN conversions
- print N/A on no data (i.e. as unprivileged user)
- fix rate calculation to show bytes (instead of a thousandth)
- print bytes as human number (i.e. 8MB) instead of 8388608
- stabilize sorting by adjusting NAN values to very tiny negative number
- sort cases by identifier
- use check snprintf
- color nice value of 0 as gray
- color cpu and memory percentages of 0.0 as gray
- color number of threads of 1 as gray
- color idle and sleeping state as gray
- color tgid matching pid (indicating main thread) as gray
If no terminal name can be found, fall back to generic display method
with major and minor device numbers.
Print special value '(none)' in case both are zero.
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.
