feat: log timings for slow work, socket clients and boot crashes

Add Timing.h and use it to log what holds up the main loop, how long a
new socket client's setup takes, slow socket sends, and how long each
web request took and from which client. Socket connects and disconnects
are logged with how long the client stayed, and late pings as warnings.
Routine sends and pings are not logged, as each line costs several ms
on a 115200 baud console.

Report a stored crash once with the crashed and running build IDs, then
erase it, since it was reported on every boot and its backtrace only
decodes against the build that crashed. Mount the file system once.
