d9e5a47058 Introduce new flag to speed up shutdown of the Online plumbing in the iOS app
Spent hours on trying to cleverly use the existing TerminationFlag
(with minor modifications to the code that checks it, and some
additional code to set and reset it), but could not get it to work.
This is simpler, but sure, using a global variable is ugly of course.
At least the new MobileTerminationFlag is very specific in semantics
and only used in the mobile apps.

e9acbe175d ShutdownRequestFlag can be a constant false in the mobile app
We don't have any user-generated signals to handle by shutting down in
an app.

One less thing to worry about. Now it's just the global
TerminationFlag that is problematic when the code runs in just one
process.

333f8994e9 Cleanup shutdown flag handling.
Pull the notification pieces out of SigUtil.cpp - not signal safe,
and invoked only from LOOLWSD anyway.

In a non-blocking world, the socket close notification sends are
instant - so more work required to count-down / timeout remaining
clients.

fa6b756346 signal handling: keep track of all socket poll wakeups & wakeup.
Instead of waiting for polls to timeout; wake them up.
