c14a45ba35 Add a platform for Performance Co-Pilot (PCP) metrics
This introduces an initial platform for extracting metrics
using the PCP performance metrics API - PMAPI(3).  It can
be used via the --enable-pcp=yes configure option.

So far I've added support for live localhost metrics only,
and only using pre-defined metrics already found in htop.
If available, all sampling is performed by pmcd(1) - else,
we fallback to htop doing the metric sampling itself (all
below the PMAPI).  When pmcd is used, it may be configured
to run children with elevated privileges, so htop does not
need to be setuid (authentication with pmcd is available).

Additionally, the PMAPI allows us to support archives (for
historical analysis and for automated regression tests in
htop).  We'll need platform-specific command line argument
additions, which isn't yet feasible in htop (not difficult
to add though).

The goal of this first version is minimal impact in terms
of modifying the htop codebase, to introduce key ideas in
PCP (metric namespace, metadata, APIs and so on) and give
us something to discuss, experiment with and build on.

c408add108 Linux: add reset to heuristic
On hard to parse command lines tokenStart might be computed to be bigger
than tokenEnd.
Reset both values in such cases.

550a141860 Add ELAPSED process column
Add process columns showing the elapsed time since the process was
started.
Similar to STARTTIME, but shows the time passed since the process start
instead of the fixed start time of the process.

Closes https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=782636

3d5b6d9282 Fix assert failure on short running thread
The following assert failure might happen on short running threads with
an empty comm value in /proc/${pid}/stat:

htop: Process.c:1159: void Process_updateCmdline(Process *, const char *, int, int): Assertion `(cmdline && basenameStart < (int)strlen(cmdline)) || (!cmdline && basenameStart == 0)' failed.

The specific task is:
    comm=''
    exe='(null)'
    cmdline='/usr/bin/ruby /usr/bin/how-can-i-help --apt'

So basenameStart is 0, while strlen(cmdline) is also 0.
