- fix header width of IO_READ_RATE
- save data in bytes (not kilobytes) to better compute rate
- fix rate data: multiply with 1000 to compensate time difference in
milliseconds
- rename unit less variable now into realtimeMs
- use Process_printBytes(..., data * pageSize, ...) instead of
Process_printKBytes(..., data * pageSizeKB, ...) to avoid wrapper
Make functions formatting data for a process field column less error
prone, unify interfaces and improve some internals.
* Process_printBytes
- rename from Process_humanNumber
- take number in bytes, not kilobytes
- handle petabytes
- increase buffer to avoid crashes when the passed value is
~ ULLONG_MAX
* Process_printKBytes
- add wrapper for Process_printBytes taking kilobytes keeping -1 as
special value
* Process_printCount
- rename from Process_colorNumber
* Process_printTime
- add coloring parameter as other print functions
- improve coloring and formatting for larger times
* Process_printRate
- rename from Process_outputRate
- use local buffer instead of passed one; this function prints to the
RichString after all
`RichString_appendWide()` is more expensive than
`RichString_appendAscii()` due to the calls to `mbstowcs(3)` and
`iswprint(3)`.
Use the latter to print the process field buffer by default.
For the following fields this theoretically can corrupt the output:
- SECATTR
- CGROUP
- CTID
`RichString_appendWide()` is more expensive than
`RichString_appendAscii()` due to the calls to `mbstowcs(3)` and
`iswprint(3)`.
Use the latter to print the process field buffer by default.
For the following fields this theoretically can corrupt the output:
- TTY
`RichString_appendnAscii()` avoids a `strlen(3)` call over
` RichString_appendAscii()`.
Use the former where the length is available from a previous checked
`snprintf(3)` call.
Keep `RichString_appendAscii()` when passing a string literal and
rely on compilers to optimize the `strlen(3)` call away.
By default, OpenBSD disables SMT (hyperthreading) cpu pseudo-cores.
This can be changed at runtime by setting the hw.smt sysctl so they
may become active later, therefore they are still present in cpu
stat structures but are marked as offline.
As done with native top(1), this drops them from the cpu summary
graphs.

* 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.
