Nathan Scott 6f9b161b24 Use the PACKAGE macro rather than htop directly, for overriding 
Allow other projects (PCP) to be able to ship an htop binary

so that its clear which (if any!) binary failed.

Christian Göttsche df752dd189 Do not override Linux process library size 
The library size in statm is unused and always 0 since Linux 2.6.

Christian Göttsche 45ab05c56a Limit deleted library check 
Reading and parsing /proc/<pid>/maps is quite expensive.

Do not check for deleted libraries if the main binary has been deleted;
in this case the deleted binary takes precedence.

Do not check in threads.  The check is void for kernel threads and user-
land threads can just inherit the state from the main process structure.

Benny Baumann 7a8a6dd828 Do not install recommended packages by default for the CI 
This ensures, the minimal dependencies we specify are sufficient.
Also this reduces fallout from broken recommendations.

Christian Göttsche faabbaa71e Linux: drop O_PATH usage 
O_PATH is available since Linux 2.6.39, but we are using fstat(2) on the
returned file descriptor in LinuxProcessList_statProcessDir(), which
is only supported since Linux 3.6.

Fixes #534

using deleted shared libraries.

line wrangling (thanks BenBE!).  Add PCP platform support for a

CWD, and so on.

Nathan Scott 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.
