Most of the synchronization was too deep in the implementation so that it did not guard everything it needed.
Now each song has precisely one mutex which must be locked for all access to its internals - this is done in the public ZMusic interface
Do not access various global objects at early stage of initialization and late stage of shutdown

The main exits are initiated from code that cannot filter this back to D_DoomMain easily so the exception is the only way to get there.
The 3 main points of exit are:
* quit/exit CCMD
* quitting the menu through ST_Endoom
* receiving a quit message on the main window.

These ones were particularly bad examples of misusing the exit handlers by temporarily installing one themselves and then calling exit to clean stuff up.
Now they just return an error code to D_DoomMain to perform a regular exit.
The main catch is now in D_DoomMain, only calling platform specific functions to handle the output for the error.
As a nice side effect, -norun can now be done without an exception, just by exiting D_DoomMain with a special exit code.

FluidSynth 1.x: these functions return 1 on success and 0 otherwise

DYN_SNDFILE=NO and DYN_MPG123=NO were ignored while DYN_FLUIDSYNTH=NO broke compilation
These options should be applied to ZMusic target instead of the main executable
As a bonus, it's now possible to build GZDoom without FluidSynth
Since this made heavy use of Windows type, those were duplicated to avoid rewriting the entire interface.
This split at least reduces the amount of code needed to refactor for making the screens work on other platforms than Windows.

Now there is only one single entry point for both, instead of previously 2 entry and 4 exit points.
This also eliminates the explicit shutdown of ZMusic. Timidity++'s two buffers have been put in containers that self-destruct on shutdown and calling dumb_exit is not necessary because the only feature requiring it is not used by any code in the music library.
Instead of trying a homegrown way to avoid recursive exceptions, let's do it with the defined procedure C++ has for this case: call std::terminate.
This allowed removing some old hackery inherited from Boom and will now hopefully allow sanitizing the exit procedure to the point that it can be done without depending on exit handlers.

The only difference here were the size values on Windows but for this initial call they have been useless for a long time. When this code was written the console buffer still had a fixed width that needed to be set before adding any text.
