Subject: Introduce Machine class for host-specific info (split from
 ProcessList)

First stage in sanitizing the process list structure so that htop
can support other types of lists too (cgroups, filesystems, ...),
in the not-too-distant future.

This introduces struct Machine for system-wide information while
keeping process-list information in ProcessList (now much less).
Next step is to propogate this separation into each platform, to
match these core changes.
