The bulk of this commit just changes std::vector<std::string> to
StringVector when we deal with tokens from a websocket message.
The less boring part of it is the new StringVector class, which is a
wrapper around std::vector<std::string>, and provides the same API,
except that operator[] returns a string, not a string&, and this allows
returning an empty string in case that prevents reading past the end of
the underlying array.
This means in case client code forgets to check size() before invoking
operator[], we don't crash. (See the ~3 previous commits which fixed
such crashes.)
Later the ctor could be changed to take a single underlying string to
avoid lots of tiny allocations, that's not yet done in this commit.

Termination flag is a very harsh way of exiting.
It works in most cases, but not when we have a
modified document. What happens is the following:
Unit-test flags for termination.
During session cleanup we have to save the modified doc.
Because save is in progress we don't 'disconnect' the view.
This leaves the view in loaded state until saving is done.
But because of the termination flag we don't wait for saving.
DocBroker sends 'exit' to child to forcefully exit.
This causes at least one assertion due to active LOKWindows (Sidebar).
Instead of the above, we flag for graceful shutdown from unittests,
and after we wait to cleanup all DocBrokers, we flag for termination.
This way, we get clean shutdown and all assertions/validations
pass, while we guarantee never to deadlock the unittests,
in case we end up waiting forever for shutdown to complete.

- target ClientSession::_handleInput(), since crashing there would bring
down the whole loolwsd (not just a kit process), and it deals with
input from untrusted users (browsers)
- add a --enable-fuzzers configure switch to build with
-fsanitize=fuzzer (compared to normal sanitizers build, this is the only
special flag needed)
- configuring other sanitizers is not done automatically, either use
--with-sanitizer=... or the environment variables from LODE's sanitizer
config
- run the actual fuzzer like this:
./clientsession_fuzzer -max_len=16384 fuzzer/data/
- note that at least openSUSE Leap 15.1 sadly ships with a clang with
libfuzzer static libs removed from the package, so you need a
self-built clang to run the fuzzer (either manual build or one from
LODE)
- <https://chromium.googlesource.com/chromium/src/testing/libfuzzer/+/refs/heads/master/efficient_fuzzing.md#execution-speed>
suggests that "You should aim for at least 1,000 exec/s from your fuzz
target locally" (i.e. one run should not take more than 1 ms), so try
this minimal approach first. The alternative would be to start from the
existing loolwsd_fuzzer binary, then step by step cut it down to not
fork(), not do any network traffic, etc -- till it's fast enough that
the fuzzer can find interesting input
- the various configurations start to be really complex (the matrix is
just very large), so try to use Util::isFuzzing() for fuzzer-specific
changes (this is what core.git does as well), and only resort to ifdefs
for the Util::isFuzzing() itself

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

The initial child spawning takes significantly longer
than subsequent ones (for obvious reasons) and this
lead to unit-tests being sensitive to the timeout
we use for child spawning. Too short, and we
spawn more than we want on startup, too long
and crash-recovery tests fail (we don't
recover fast enough, as we wait too long before
spawning new children).
Dynamically setting the timeout allows us to give
longer timeout at startup, and reduce it afterwards.

It is is complicated enough to build the iOS app. Requiring GNU
libtool brings with it the risk of polluting the command environment
as there already is a completely different command in macOS with the
same name, /usr/bin/libtool. And as GNU libtool was used only to build
the unit tests for the "normal" server-based Online that are built and
run only on Linux anyway, we don't really need any of the
"portability" that GNU libtool brings.
Without GNU libtool, we compile all the $(wsd_sources) (see
test/Makefile.am) that the unit-* tests use into a single object file,
WsdSources.o. (Because they need to be compiled as PIC we can't use
the already compiled object files for the Online server programs.)
This required some additional minor changes to a few source files.

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.

Reduce the number of different kinds of identifiers for threads that
are displayed in various places. Use the number that you get with
pthread_threadid_np(), in hex, which is the same that Xcode (i.e.
lldb) displays in its "thread list" command. It also is the same
number that osl_getThreadIdentifier() returns.

The default deflate level of 6 is quite slow
and the benefits are hardly worth the high
latency that users experience.
Tested on a writer document with some small
images and a few pages of text:
Level 4 gives virtually identical compression
ratio to level 6, but is between 5-10% faster.
Level 3 runs almost twice as fast as level 6,
but the output is typically 2-3x larger.
Perhaps this should be exposed via config
so it would be possible to reduce latency
due to compression when CPU is scarce but
network bandwidth ample, and vice versa.

(What we cache is also the textual data: URLs even if we store them
using .png file names.)
This avoids the current back-and-forth-encoding: First we
base64-encode the complete binary "tile:" message (one text line
followed by a newline and the binary PNG) to pass to WebKit, then in
the JavaScript snippet passed to WebKit we decode the base64 and turn
it into an ArrayBuffer, and then we unpack the ArrayBuffer and encode
the PNG part to use as a data: URL.
Also fix unexpected concatenation error in Poco::URI::encode generating
eg. authorid=localhost0 xauthorid=localhost0localhost0 in the output.
