9f41dc3332 MemoryMeter: show shared memory before cached

Show it beforehand.

0cfc9b0980 LinuxProcessList: refactor /proc/stat parsing
Combine reading CPU count and CPU usage, only open the file once.
Do not separately initialize totalPeriod and totalTime, cause the value
0 is handled in Platform_setCPUValues().

Take the number of currently running process from the entry
procs_running in /proc/stat instead of counting all scanned process
with state 'R', to include hidden tasks, e.g. threads.

61ef1134d9 Move generic (shared) code into its own sub-directory
Code that is shared across some (but not all) platforms
is moved into a 'generic' home. Makefile.am cleanups to
match plus some minor alphabetic reordering/formatting.

5b50ae3aa3 Separate display from sampling in SysArch and Hostname Meters
Several of our newer meters have merged coding concerns in terms
of extracting values and displaying those values.  This commit
rectifies that for the SysArch and Hostname meters, allowing use
of this code with alternative front/back ends.  The SysArch code
is also refined to detect whether the platform has an os-release
file at all and/or the sys/utsname.h header via configure.ac.

00339087b0 Fix integer sizing issues in the DiskIO Meter
On Linux kernels the size of the values exported for block
device bytes has used a 64 bit integer for quite some time
(2.6+ IIRC).  Make the procfs value extraction use correct
types and change internal types used to rate convert these
counters (within the DiskIO Meter) 64 bit integers, where
appropriate.

fd4e6b432b Use MainPanel type in State struct
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.

51e79ddc07 [#480] SysArchMeter to view kernel/arch info
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.

fdaa15bd8d Linux: overhaul io process fields
- 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

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.

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)."

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.
