This includes loading a level and busy-waiting for a sound to play.
Also block these loops and the sounds they wait for in network games to avoid problems from longer delays here.
The problem seems to be directly inherited from ZDoom which shows the same issue with screen wipes.
Fixes#297
* Remove fix16.h/cpp and utilise library from m_fixed.h.
* Extend m_fixed.h with two inline functions for int to/from float operations.
* Replace fix16_floor operations with those from xs_Float.h
* Replace multiple Q16.16 conversions from 0 to just be 0.
* Replaced all found in-game bit-shifts and multiplications/divisions with inline functions from m_fixed.h
* Replaced many casts of FRACUNIT as double in SW's panel.cpp as it is converted to double by way of type promotion.
* Fixed missed precision fixes in SW's panel.cpp where some types weren't declared correctly.
* Replaced 100+ `Cos()/Sin() >> 16` operations for Blood with inline functions `CosScale16()/SinScale16()`.
This is because 'classic' aim mode will reset the view if the mouseaim key is not pressed.
The problem with this is that an empty input packet will trigger a view reset. If the meaning is inverted the default aim mode is free mouse view which doesn't try to alter any view state and is therefore preferable for an empty packet.
Fixes#292
This avoids crashing on LEV20, but the whole thing is simply too poorly implemented to actually work - this needs to be redone so that the map transition does not occur in the middle of the game ticker.
Since this status bar depends on explicit updates, this data needs to be restored after loading, and just saving it out is the easiest way to ensure that.

In particular this means to remove the option to disable widescreen aspect ratios. The way this was handled makes no sense with the current render backend.
The aspect ratio code will have to be redone entirely to properly obey the backend's settings.
None of this was really working anymore, but will have to be rethought once a network stream exists again.
But even then, this is better sent as a separate command, and in MP only.
* ambient sounds were constantly restarted resulting in garbled sound.
* sound priorities were not checked. This was used to limit some sounds to one instance per actor or to allow terminating other sounds playing on the same actor.
* Player movement is close, but not exactly as it was. Requires more work if it is to be considered.

Currently the bit fields are still separate and they have to be merged, but for now the added memory does not matter.
Having this structure in the common parts will allow work on consolidating the input code, though.
This needs to be called unconditionally for every frame being rendered, not all of the game modules did that.
Placing this call here ensures that it is independent of anything the games do.
