* Rename internal identifier from TTY_NR to just TTY
* Unify column header on platforms
* Use devname(3) on BSD derivate to show the actual terminal,
simplifies current FreeBSD implementation.
* Use 'unsigned long int' as id type, to fit dev_t on Linux.
Only on Solaris the terminal path is not yet resolved.
Refactor the sample time code to make one call to gettimeofday
(aka the realtime clock in clock_gettime, when available) and
one to the monotonic clock. Stores each in more appropriately
named ProcessList fields for ready access when needed. Every
platform gets the opportunity to provide their own clock code,
and the existing Mac OS X specific code is moved below darwin
instead of in Compat.
A couple of leftover time(2) calls are converted to use these
ProcessList fields as well, instead of yet again sampling the
system clock.

The end goal is to consolidate all the points in htop that can only work in
live-only mode today, so that will be able to inject PCP archive mode and have
a chance at it working.
The biggest problem we've got at this moment is all the places that are
independently asking the kernel to 'give me the time right now'.
Each of those needs to be audited and ultimately changed to allow platforms to
manage their own idea of time.
So, all the calls to gettimeofday(2) and time(2) are potential problems.
Ultimately I want to get these down to just one or two.

BenBE points out that some header meters use values calculated
during process scanning - make sure we scan processes first in
order that current values are displayed.

Always show the number of kernel and userland threads, even when they
are disabled to not be shown in the process list.
The data is already available and might improve understanding the system
utilization.
Use a shadow color in case the kind of thread is hidden, else the normal
meter one.
One review request relating to the PCP platform is to have
a clearly separate binary from the regular htop so that we
have no confusion as to what is being requested to run, to
aid debugging, and a bunch of other good reasons.
This commit renames htop.c to CommandLine.c and provides a
minimal htop main function for 'native' platforms to use.
The PCP version of this will setup libpcp.so and then call
the same CommandLine_run function as regular htop.

Follow up on the two items of feedback from cgzones review,
and resolve a build failure picked up by CI on Mac OS X.

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.

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.
* Set process data for:
- minflt
- majflt
- processor
- nlwp
* Drop unimplemented nlwp column
* Scan userland threads
* Mark a 'Thread is currently on a CPU.' with 'R', and processes
'Currently runnable' with 'P', do confine with man:ps(1) and Linux.
See https://man.openbsd.org/ps.1
* Show CPU frequency
Currently the tree-view is empty on OpenBSD when kernel threads are
hidden, cause the kernel thread 'swapper' has pid 0 and gets treated as
root of the tree and parent of 'init'.
Do not build any tree with a pid 0 root node.
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)

The local stack buffer does not need to be cleaned to zeros when
- just initialized, cause the length is set to 0 and the first
character is set to '\0', so all printing functions will safely stop
- no further used, i.e. the variable goes out of scope
