Silke Hofstra 696f79fe50 Dynamically scale the ST_UID size to support 32-bit UIDs 
While most Unix-like systems use 16-bit user IDs,
Linux supports 32-bit UIDs since version 2.6.
UIDs above 65535 are used for UID namespacing of containers,
where a container has its own set of 16-bit user IDs.
Processes in such containers will have (much) larger UIDs than 65535.

Because the current format strings for `ST_UID` and `USER`
are `%5d` and `%9d` respectively, processes with such UIDs
lead to misaligned columns.

Dynamically scale the `ST_UID` column and increase the size of `USER`
to 10 characters (length of UINT32_MAX) to ensure that the user ID always fits.

Additionally: clean up how the titlebuffer size calculation and ensure
the PID column has a minimum size of 5.

Christian Göttsche 2844429f15 NetBSD: scale CPU frequencies 
Use a value type of 'long int' to avoid ENOMEM failures of sysctl(3).

Also check for "machdep.tsc_freq", scaled in MHz.

Benny Baumann b42c441ee0 Use proper metric to detect kernel threads 
Querying kernel threads with `ps -o pid,lid,flags,state,lname -sp 0`
gives that kernel threads have state `K` and flags have mask `0x20000` set.
This corresponds to `LW_SYSTEM` in kernel which is mapped as `L_SYSTEM`/`P_SYSTEM` for userspace.

Sohaib Mohamed 6f2021f3d9 PCP: support for 'dynamic columns' added at runtime 
Implements support for arbitrary Performance Co-Pilot
metrics with per-process instance domains to form new
htop columns.  The column-to-metric mappings are setup
using configuration files which will be documented via
man pages as part of a follow-up commit.

We provide an initial set of column configurations so
as to provide new capabilities to pcp-htop: including
configs for containers, open fd counts, scheduler run
queue time, tcp/udp bytes/calls sent/recv, delay acct,
virtual machine guests, detailed virtual memory, swap.

Note there is a change to the configuration file path
resolution algorithm introduced for 'dynamic meters'.
First, look in any custom PCP_HTOP_DIR location.  Then
iterate, in priority order, users home directory, then
local sysadmins files in /etc/pcp/htop, then readonly
configuration files below /usr/share/pcp/htop.  This
final location becomes the preferred place for our own
shipped meter and column files.

The Settings file (htoprc) writing code is updated to
not using the numeric identifier for dynamic columns.
The same strategy used for dynamic meters is used here
where we write Dynamic(name) so the name can be setup
once more at start.  Regular (static) columns writing
to htoprc - i.e. numerically indexed - is unchanged.
