Christian Göttsche 7b293dc3e2 Linux: fix --drop-capabilities

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.

Fix integer sizing issues in the DiskIO Meter

Nathan Scott 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.

Nathan Scott 2d1839289e Fix integer sizing issues in the NetworkIO Meter 
On Linux kernels the size of the values exported for network
device bytes and packets 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 NetworkIO Meter) 64 bit integers,
where appropriate.

Christian Göttsche f273bfd083 Linux: restore memory calculation regarding HugePages 
Subtract the total amount of huge page memory from total and used memory.

Restores behavior from #450 (see also #447)

Christian Göttsche 3d497a3760 Linux: overhaul memory partition 
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).

Christian Göttsche 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.

ahgamut 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.

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)."

Nathan Scott c75c5ef9c6 Minor cleanups to platform-specific init and done 
Move platform-specific code out of the htop.c main function
and into the platform sub-directories - primarily this is
the Linux procfs path check and sensors setup/teardown; not
needed on any other platforms.  No functional changes here.
