Christian Göttsche ee9e7edbc1 Solaris: handle ERR macro redefinitions
On OmniOS /usr/include/sys/regset.h redefines ERR to 13 - \r, breaking
the Enter key.
Since ncruses macros use the ERR macro, we can not use another name.

Closes: #634

Christian Göttsche fdda291a0e Solaris: add kstat lookup wrappers
The system interfaces kstat_lookup() and kstat_data_lookup() take a
non-constant string parameter, but passing string literals is valid.

Add wrapper functions to ignore all the const-discard warnings.

Christian Göttsche 323d7e73aa Linux: update IO fields
- 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

Christian Göttsche b41e4d9c54 Rework process field print functions
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

Christian Göttsche 6bbb454881 LinuxProcess: print default buffer in ascii
`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

Christian Göttsche 436808ff99 Use RichString_appendnAscii where possible
`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.

Stuart Henderson feec16cbb5 don't include offline CPUs in summary for OpenBSD
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.

* 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.

Nathan Scott 356488aa53 Request the realtime and monotonic clock times once per sample
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.

Sohaib 421bdeec60 Merging all the points related to calculating time in one place
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.
