This had two different flags that were checked totally inconsistently, and one was not even saved.
Moved everything into a few subfunctions so that these checks do not have to be scattered all over the code.
This is what should be audible. To prevent other levels from playing sound, all entry points check whether the sound playing entity belongs to the current UI level.
- widened ttl variable in particle_t to short to allow longer living particles than 6 seconds.
- reordered fields in particle_t to reduce struct size a bit.
- cleaned out a lot the SafeDivScale stuff in m_fixed.h. The only SafeDivScale variant still in use was #16 for FixedDiv, so all the SafeDivScale stuff has been removed and the 16 variant renamed to FixedDiv because that's the only form in which it is still being used. (2x in R_DrawVoxel and 1x in ACS's FixedDiv PCode.)
- removed Build notice from m_fixed.h because aside from the inlines includes there is nothing here from Build anymore.
SPF_NOTIMEFREEZE processes particles with this flag regardless of time freeze. The endsize parameter changes the scale of the particle to that size throughout its lifetime linearly.
This required some changes to the Trace function because it turned out that the original was incapable of collecting the required information:
* actors are now also linked into blockmap blocks on both sides if they occupy the boundary of a sector portal.
* Trace will no longer set up parallel traces in all parts connected with sector portal, but only use one trace and relocate that on the actual boundary.
The only reason this even existed was that ZDoom's original VC projects used __fastcall. The CMake generated project do not, they stick to __cdecl.
Since no performance gain can be seen by using __fastcall the best course of action is to just remove all traces of it from the source and forget that it ever existed.
This code was ported from the 2005 floating point version, at one point it replaced 128 with 0.5, but 128 as a fixed point value needs to be 1/512. as a floating point value.
This is the last bit of play code that needed to be altered, what's left is the underlying data representations of vertices, linedefs and sectors.

- Converted P_MovePlayer and all associated variables to floating point because this wasn't working well with a mixture between float and fixed.
Like the angle commit this has just been patched up to compile, the bulk of work is yet to be done.
