* 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 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.
* removed the timer callback stuff that came back through the backdoor.
* do not use gameclock in the UI code - use the underlying timer directly.
* UpdateSounds must still use totalclock, until this can be refactored in its entirety.

Revert "SW: Remove ScrollMode2D extern boolean and move into PLAYERp struct."
This reverts commit 31eb55c1fa.
For ambient sounds that can be cleanly restarted a new 'transient' flag was added so that these do not get written out.
Tested on SW so far, other games yet to do.
After merging the CD enabling CVAR they had the same default (off) as Blood which is wrong.
This also addresses other music related issues, like not properly cycling through the RR music.
* removed all cases of getting a sound handle and checking it later.
* In particular, refactor the cases where the handle is stored in a static local variable. These are fundamentally unsafe because nothing maintains these local variables.
* finished rewriting the PlaySound function. Let's hope this is what was intended, the entire coding here was not particularly good, mixing high and low level sound handling all on the same level.
* call the update routine each tic and not merely every 4th or 8th one, this kind of granularity was ok in 1997 but not with a modern sound engine.
