Nathan Scott 253ff23f9e Use a platform-specific routine for long option usage

Nathan Scott 0ada9f325f Move libcap use to (Linux) platform-specific code
The libcap code is Linux-specific so move it all below
the linux/ platform subdirectory.  As this feature has
custom command-line long options I provide a mechanism
whereby each platform can add custom long options that
augment the main htop options.  We'll make use this of
this with the pcp/ platform in due course to implement
the --host and --archive options there.

Benny Baumann 57e0ce7b4f Use `#if defined()` syntax when `#elif defined()` is present
This prefers the `#if defined()` syntax over the `#ifdef` variant
whenever there's also a `#elif defined()` clause, thus making the
multiple branching structure more obvious and the overall use
more consistent.

Christian Göttsche f46fcf094e Linux: Rework libsensors parsing
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)

Combine reading CPU count and CPU usage, only open the file once.
Do not separately initialize totalPeriod and totalTime, cause the value

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.

Nathan Scott 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.

Nathan Scott 00339087b0 Fix integer sizing issues in the DiskIO Meter

appropriate.

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

Once the condition has been met, bail out early for the next couple of
scans.

* This will allow us to override the sortKey in a global way without having
  to edit each OS-specific file.

Nathan Scott 75e9f9a8d9 Cull the definitions of pageSize and pageSizeKB from CRT.c
By storing the per-process m_resident and m_virt values in the form
htop wants to display them in (KB, not pages), we no longer need to
have definitions of pageSize and pageSizeKB in the common CRT code.

These variables were never really CRT (i.e. display) related in the
first place.  It turns out the darwin platform code doesn't need to
use these at all (the process values are extracted from the kernel
in bytes not pages) and the other platforms can each use their own
local pagesize variables, in more appropriate locations.

Some platforms were actually already doing this, so this change is
removing duplication of logic and variables there.

Nathan Scott f704baeb82 Drop unused global ProcessList memory fields
The global ProcessList structure contains a couple of unused
fields.  'sharedMem' has never been used by any Meter, since
its not been anything other than zero in Linux /proc/meminfo
for many, many years.  The freeMem field is only used in the
usedMem calculation, so it can reside on the stack like some
other memory variables used within-calculations-only and not
exposed to the user via a Meter.

needed on any other platforms.  No functional changes here.
