Revert "Change angle_t handling in Lua."

a courtesy fuck you to gitlab for making me have to keep
the previous screwed up bullshit in this branch.

This reverts commit 4625118e.

This reverts commit 280e932f.

This partially reverts commit ef0e61fc.

Not when we have properly working ones!

This reverts commit 474ad01b.

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 9d36cf37.

Revert "MF2_PUSHED is now MFE_PUSHED, for the simple reason that it makes more sense as an eflags object flag than a flags2 object flag!"

This reverts commit c8c78780.

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.

See merge request !38

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

Crashfix Lua hook_NetVars

Argh, I knew I was forgetting something! archFunc is the argument to be passed to the hooks, not tables!

This function is intended to leave the stack in the same state it recieved it.

Fixes I_Assert failure crash due to hooks working differently now.

you have space for a null terminator there...

A test WAD for all possible use cases I can think of
can be found here:

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

BACKPORT: special stage fade

literally a straight cherry-pick of the old repository, this is a very simple change after all.

See merge request !44

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

Same as the commit in internal, minus toaster's name (by request, of course.)

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
