This implements the concept of 'dynamic screens' in htop, with a
first use-case of pcp-htop displaying things like top-filesystem
and top-cgroups under new screen tabs.
From the pcp-htop side of things, dynamic screens are configured
using text-based configuration files that define the mapping for
PCP metrics to columns (and metric instances to rows). Metrics
are defined either directly (via metric names) or indirectly via
PCP derived metric specifications. Value scaling and the units
displayed is automatic based on PCP metric units and data types.
This commit represents a collaborative effort of several months,
primarily between Sohaib, BenBE and myself.
