Some fixes for portals
Specifically the following things are fixed in this branch:
* a memory leak resulting from not clearing away clipping-related arrays each tic you view a portal
* a very specific crash to do with portals sometimes (unintentionally) using a hack on drawsegs that don't actually belong to them ...which results in a crash if the drawsegs in question have midtextures. I reported it on the MB a year ago, with a test map included there: https://mb.srb2.org/showthread.php?t=38199&page=4#79
* another specific crash to do with mirrored (horizontally flipped) sprites that are scaled, particularly when you cover up the left edge of them via portals at the least. Needs more testing to be absolutely sure this is fixed, and is also reproducable in the test map linked in the post above
May be fine to merge changes into master too, I don't really know exactly

Camera fix
This fixes the third person camera being silly around intangible PolyObjects, particularly the fact they can affect the camera's floorz and ceilingz even though I see no reason why they should do so.
Also a good reminder that POF_SOLID is the same as POF_CLIPLINES and POF_CLIPPLANES combined, which is probably how this issue came about to begin with. Can't say that with certainty of course.

P_RandomChance is now a macro for something that should happen a
certain percentage of time.
P_SignedRandom was moved to a macro. Nobody cared.
# Conflicts:
# src/p_inter.c
This actually passes most diehard tests, as opposed to the old RNG.
It's also similarly fast.
Internally the PRNG generates a fixed point number from [0,1) now,
which makes P_RandomKey and P_RandomRange much easier to
calculate. P_Random is just a simple shift, as well.
Also, the lack of floating point math in P_RandomKey and
P_RandomRange now is probably for the best.
Also makes comptime.bat work with git if able.
Development builds will now show the branch and the SHA1 hash of the revision. Also been tested to work with subversion, where it displays "Subversion r####". You know, just in case.
There is a caveat to this: The first time EvalMath is used, a
deprecated function warning will be shown to the user that tells
them to use _G[] instead.
This reverts commit 9d36cf37bd.
This appears to fix a few holes that have been known to appear with FOF slopes sometimes, dunno how they actually came about exactly but this apparently sorts them out
Lua sector lines
Adds support for "sector.lines" in Lua, an array containing all the linedefs in a particular sector variable:
#sector.lines returns the number of lines in the sector.
sector.lines\[ _i_ \] (e.g. sector.lines[0], sector.lines[1], sector.lines[2], etc ....) gives you individual linedefs in the sector. If the number you supply is equal to or greater than #sector.lines, this returns nil.
Test script for your benefit: (see comments)
Type "luatest" in console in any level and you'll get a few print messages that tests these features for sectors[0]
See merge request !32
SOC_**** lump name support
Exactly what it says on the tin: lumps with "SOC_" prefix now are read as SOC lumps like with MAINCFG/OBJCTCFG. Go nuts.
As a bonus, I've changed things with SOC lump detection so MAINCFG, OBJCTCFG and the new SOC_**** lumps are loaded in the order you find them in WAD files (rather than an arbitrary load-MAINCFG-then-load-OBJCTCFG thing as before). All of these are still loaded after Lua scripts though, mind.

Lua video lib expansion
New video/drawer library functions for hud.add to use:
v.width() and v.height() return the screen width and height respectively (in other words you get the screen resolution), while v.renderer() returns the string for the renderer used ("software", "opengl", or "none").
Possibly add more stuff later, but for now these things at the least can be merged in next
See merge request !40
Add PlayerSpawn hook to Lua
I don't know how I did this but I did. Something about staring at code from 3AM till 5AM...
Here's a test script too:
```Lua
addHook("PlayerSpawn", function(player) player.health = 99 end)
```
See merge request !48
Version constants for Lua
Pretty simple thing. Allows scripters to use VERSION, SUBVERSION, and VERSIONSTRING to check the game's version and potentially futureproof scripts. Have tested and confirmed working on my end.
See merge request !55
BACKPORT: removal of music slots
Relevant commits cherry-picked. Basically everything except the internal music track name switches.
See merge request !43
The funny thing is you really can't see ANY change here unless you have a sloped FOF intersecting a sector floor/ceiling (and a second FOF on the other side), which has other problems anyway lol
BACKPORT: FF_ANIMATE simplistic state animations
this is a lot more complex due to the need to remove the dispoffset related code as well as a lot of the redefinitions; combined with the code changes due to the sprite2 system in internal master.
~~BEFORE ACCEPTING THIS: get sryder to look at and fix any possible brokenness with OpenGL MD2s~~
See merge request !45
Fof flag change hotfix
This fixes rendering issues caused by changing FOF flags mid-level via Lua or linedef type 445. Everything else that toggles FF_EXISTS already had this fix it turns out.
Not sure if this is safe for master too, could someone check that for me?
See merge request !53
This fixes how removing certain flags (such as FF_EXISTS) from FOFs can cause HOMs on walls bordering their target sectors. Also fixes how the force-FOF-to-vanish linedef special can leave behind the FOF's shadow
Fix chain launching
Basically you're not allowed to launch off a chain the frame you touch it anymore.
Coincidentally the changes here allow you to actually use PF_*STASIS in a Lua script now and have it work as you'd expect it to (it lasts for a tic).
See merge request !49
cpuaffinity/sdl_mixer changes
Hopefully this will alleviate SDL2 sound issues.
If not, hopefully this will give us info on what the hell is going on.
