S1 #11: the System App: tasks, memory, network and system, live

Browse Source 
Five views, Tab between them: Overview (each core's load, memory,
traffic, battery, two minutes of load), Tasks (share of a core over the
last second, lowest free stack, flagged under 512 bytes; `s` sorts),
Memory (free heap against the floors of Q86), Network (bytes per
service, and what's moving now), System (what `info` prints, plus
battery, card, radio, GNSS). It samples once a second and keeps history
only while open.

The arithmetic is host-tested, including the trap found on the device: a
task's run-time counter only moves when it's switched out, so the task
that samples (the main loop, alone on its core) gets what's left of its
core. `tasks` now samples across a second of normal running instead of
inside its own wait. The main loop uses 100 % of core 1 at rest (#40).
