Nathan Scott cb61865bb9 Add array bounds checking for the Process_fields array (covscan)
Coverity scan reports there may be a code path that would cause
an overrun in the (relatively new) ScreenSettings code where it
evaluates default sort direction.  Add bounds check and default
to descending instead of a potentially invalid array access.

Explorer09 ee1bf2f917 Process: Fix PID & UID column widths off-by-one error
If the max PID or UID value for a platform is exactly a power of ten
(10000, 100000, etc.) the column widths of PID and UID would be 1 char
less than the correct number of digits. This is caused by the wrong
rounding function (ceil(x)); change to the correct one (trunc(x) + 1).

Fabrice Fontaine 4ccad46045 configure.ac: fix static build with hwloc
Retrieve hwloc dependencies through pkg-config to avoid the following
static build failure:

checking for hwloc_get_proc_cpubind in -lhwloc... no
configure: error: can not find required library libhwloc

This build failure is raised because without pkg-config, hwloc
dependencies such as libxml2 are not retrieved:

Kumar 6133cac721 Process: Handle rounding ambiguity between 99.9 and 100.0
Depending upon default behavior of the compiler and floating-point
environment, compiler could round down the value between "99.9" and
"100.0" to "99.0", instead of rounding it to the nearest value, "100.0".

Note: The floating-point environment access and modification is only
meaningful when "#pragma STD FENV_ACCESS" is set to "ON"[1]. Otherwise
implementation is free to assume that floating-point control modes are
always the default. So it would be a good idea to address the rounding
ambiguity between "99.9" and "100.0" to become compiler agnostic.

Kumar da653f8148 Process: Show only integer value when CPU% more than 99.9%
When we run a process which utilizes CPU between 100.0% and 999.9%, htop
shows an unnecessary decimal character at the end of the value. For
example, '100.x' and '247.x' become '100.' and '247.' respectively.

When CPU utilization is less than and equal to '99.9%', show the result
with single digit precision and if result is less than four characters,
pad it with the blank space. When CPU utilization is greater than
'99.9%', show only integral part of the result and if it's less than
four characters, pad it with the blank space.

Closes: #946

Charlie Vieth d35db47c9a darwin: lazily set process TTY name
Fetching the TTY name of a process is extremely expensive on darwin and
the call to devname accounts for 95% of htop's CPU usage when there is
high process turnover (this is mostly due to devname calling lstat,
which is incredibly slow). This can make htop unresponsive.

To mitigate this only set the process TTY name if the it is being
actively displayed (PROCESS_FLAG_TTY), which by default it is not
on darwin.

Denis Lisov fa3e0d06c2 ProcessList_buildTree: produce sorted tree
ProcessList_buildTree does not need any particular sort order for

sort unnecessary.

Denis Lisov 82dce5cf8e ProcessList_buildTree: sort by parent for fast search
ProcessList_buildTreeBranch used to search for children with a linear

process count. Pre-sorting the list by parent PID (if known) makes it
possible to select the correct slice by bisection much faster.

build: use AC_CANONICAL_HOST, not AC_CANONICAL_TARGET
htop is a program which will be run on CHOST after cross-compilation;
CTARGET is only for a small number of cases where a program itself outputs
code (so you might cross-compile a compiler which spits out code for a third
architecture/platform).

We want to use AC_CANONICAL_HOST to check CHOST for the platform currently
being used to build htop.

The confusion around this issue was compounded by a mistake in autoconf-archive
which has since been fixed (AX_PTHREAD pulled it in incorrectly).

Jessica Clarke 9512fd7930 FreeBSD: Add support for showing process emulation
This displays the same output as ps's -o emul, which is the system call
emulation environment, or ABI, in use. This will typically be FreeBSD
ELF32 or ELF64, but can also be Linux ELF32 or Linux ELF64 when running
Linux binaries under FreeBSD's Linuxulator binary compatibility layer.
The column width of 16 is chosen to match KI_EMULNAMELEN's value of 16,
most of which is normally used up as FreeBSD ELF32/64 is 13 characters.
