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.

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.

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.

(cherry picked from commit ad7964393eadb68873b820e0a620fb40f1e1b06a)

The async-signal-safe functions to get thread-id
and thread-name, which cache the results, are
faster, cleaner, and signal-safe. No reason why
we shouldn't always use them.
Especially since it appears the logic was
inverted in Log::prefix, such that the signal
un-safe calls were made during signal-handling,
and the safe ones were called otherwise!
Instead of passing the signal-safe flag to
Log::prefix, we pass the buffer size, for
improved security.
Furthermore, reduce header dependencies
and reduce clutter.

Re-think the plumbing between the different parts of the C++ Online
code. Do try to have it work more like in real Online on all but the
lowest socket level. Except that we don't have multiple processes, but
threads inside the same process. And instead of using actual system
sockets for WebSocket traffic between the threads, we use our own
FakeSocket things, with no WebSocket framing of messages.
Reduce the amount of #ifdef MOBILEAPP a bit also by compiling in the
UnitFoo things. Hardcode that so that no unit testing is ever
attempted, though. We don't try to dlopen any library.
Corresponding changes in the app Objective-C code. Plus fixes and
functionality improvements.
Now it gets so far that the JavaScript code thinks it has the document
tiles presented, and doesn't crash. But it hangs occasionally. And all
tiles show up blank.
Anyway, progress.

Re-think Linux vs mobile ifdefs a bit. Use #ifdef __linux only to
surround code that actually is Linux-specific. Use #ifdef MOBILEAPP
for code that is for a mobile version (with no separste wsd, forkit,
and kit processes, and with no WebSocket protocol used).
Bypass UnitFoo for mobile. Possibly we do want the UnitFoo stuff after
all on mobile, to run in some special testing mode? Hard to say, let's
skipt it for now.
Also gets rid of a potentially problematic strncpy() use that causes a
gcc warning: specified bound 256 equals destination size
[-Werror=stringop-truncation].
(Whether that would have caused a problem or not depends on how
LogPrefix would have been used, and whether it ever would have been
filled completely, without any terminating nul character, by that
strncpy().)

Now all logging is done after checking if the
level in question is enabled or not (thanks to
the macros LOG_XXX), which saves unnecessary
conversions and stringification when said level
is disabled.
