Log data to std::cerr - so it goes to the log files.
Dump PSS / Dirty per child process for comparison.
Copy the child socket array before operating on it to fix a crash.
Add debug to ensure we are getting each child's true size.
Instead of trying to inform the sysadmin (which we did not yet try to
do in any meaningful way), inform all connected clients (even those
editing other documents).
We use 'error: cmd=internal kind=diskfull' as the message to the
clients. The loleaflet code needs to be updated to handle that
carefully by displaying a very prominent message that tells the user
that all bets are off.
Also add a unit test for the functionality.
Document the new protocol details.
The code for this alert functionalty became a bit less elegant than I
like because of the way we include Util.cpp in the unit test 'test'
program.
Still need to add code to check for disk full in more places, not just
when saving a cached tile or font. Probably we should even actually
check for disk space on the file system(s) we use getting alarmingly
low, not just check for file writing operations that fail. Later.
Tile queue was used to process canceltiles commands.
Since those are handled by TileCache, there is no need
for queues and the threads that pump them.
But because these queues were also used to buffer between
WSD internals and clients, such that a slow client wouldn't
block WSD while sending back tiles, it is necessary
to reword that logic.
In subsequent commits that will change as well.
With this change not only do we save a thread per client,
but we also reduce latency of tile, and improve typing
responsiveness, by almost 3x or more! Latencies are
down to ~15ms from almost 50ms.

If TDOC is not defined, this is broken. Defining it as "" in that case
won't fix anything. Use abs_top_srcdir to be less dependent on what
the cwd is when the code runs.

Indeed, tests are built when invoking make in loolwsd
directory, thereby helping catch build errors in test
before committing.
