* Change variable types of time values from signed to unsigned.
* Change variable naming for consistency: `totalMinutes`, `totalHours`,
`totalDays` for total values and `minutes`, `hours`, `days`, etc. for
remainder values. (`years` remains an exception as there is no larger
unit than years)
* Use `unsigned long long` type for `years` value to prevent a
potential overflow.
* The time units are now evaluated from small to large, in the hopes
that small values would print faster. (There is no performance test
for this claim.)
* The days unit is now printed when `totalHours` is at least 24.
(Issue htop-dev#1317) There is room in the new code to revert to the
old threshold (totalHours < 2400).

This implements our 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. However the idea is more
general than use in pcp-htop and we've paved the way here for us
to collectively build mroe general tabular screens in core htop,
as well.
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 myself, Nathan and BenBE.

This commit refactors the Process and ProcessList structures such
they each have a new parent - Row and Table, respectively. These
new classes handle screen updates relating to anything that could
be represented in tabular format, e.g. cgroups, filesystems, etc,
without us having to reimplement the display logic repeatedly for
each new entity.
