7f25109f72 tdf#128502: Chunk of work to enable "multi-tasking" in the iOS app
Seems to not cause any serious regressions in the iOS app or in "make
run", but of course I am not able to run a comprehensive check of all
functionality.

42c8417e34 admin fuzzer: improve this further, so it can find interesting paths faster
1) Don't actually kill anything with the kill command, otherwise kill(0,
SIGKILL) will kill the fuzzer itself.

2) Don't require a valid signature when authenticating with JWT, since
the private key is generated on each process startup.

3) Log when the JWT would be invalid due to an expired timestamp.

9290981013 wsd: debug: add env variable "PAUSEFORDEBUGGER" to attach debugger
It is painful to check and search manually the PID to attach the LOKit
process when exists several pre-spawned waiting to load a document.

This patch helps to attach the debugger when the LOKit process is about
to load a document then send the "signal SIGUSR1" to resume it.

3ebbc6213b wsd: avoid malloc in signal handler
malloc is not signal safe, and must not be called
from signal-safe functions. If malloc itself signals,
calling it in the signal handler can deadlock.

Luckily, we only needed malloc for getting the
backtrace strings. Now we just write directly to
stderr, which is faster, cleaner, and safer.

b74306acd5 wsd: replace mutex in signal handler

This replaces the logic with a simple counter that
serves the purpose just as well.

If we get a double signal, we log and ignore.

7a976488f0 wsd: cleanup the global flag accessors
The following flags are affected:
ShutdownRequestFlag
TerminationFlag
DumpGlobalState

Since it's common to grep for all places
that set or reset these global flags, it
makes more sense to have explicit functions
for each operation. Now we have set and reset
accessors where appropriate and get is reserved
for read-only access.

This changes the getters to only return
the boolean value of these flags rather than
a reference to the atomic object, now that
they are read-only.

Also, a few Mobile-specific cases were folded
either with other Mobile-specific sections, or
they were now identical to the non-Mobile case
and therefore deduplicated, making the code
cleaner and more readable.

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.
