What changed in EDuke32, build by build

Add updatesectorneighbour() and updatesectorneighbourz() and make them accessible to CON to allow searching for nearby neighbouring sectors from a known sector.

Untie EVENT_ALTFIRE from the conditions required to trigger EVENT_FIRE

Add gamefunc_Alt_Weapon and EVENT_ALTWEAPON back in

Add EVENT_RESETGOTPICS which gives scripts the chance to reset gotpics (and similar effects trackers) for effects that run in EVENT_DISPLAYROOMS.

Allow CON-specified actions to override hardcoded tsprpicnum behavior of PLAYERONWATER, CAMERA1, and RAT

Gamevar system maintenance

Make CLIPMASK0 and CLIPMASK1 regular defined tokens instead of read-only gamevars

CON VM maintenance

Fix a potentially funny bug in the CON parser

Use function overloading to clean up some of the CON event execution function names

Add EDUKE32_PREDICT_FALSE to EVENT_ANIMATESPRITES check in G_SaveMapState() and G_RestoreMapState()

Fix potential OOB memory access if the player's curr_weapon member is set out of range from CON

Fix "findnearactor" family of CON functions

Fix CON issues introduced in r7357 and r7358

Free inthash tables used by the CON compiler using the contents of inttables[] instead of listing them explicitly in C_Compile()

Implement a new VM dispatch method using an explicit jump table

Macro-ize CON keyword tokens in gamedef.h and gameexec.cpp

Move five missed opcodeless keywords down in gamedef.h

#ifdef out deactivated stuff that should not be half-in, half-out

Use existing viewingrange and yxaspect for showview so it matches that of the main view

Remove read only bit from SPRITE_SECTNUM and SPRITE_STATNUM in m32script

Add mousebits gamevar to m32script for querying mouse button states

Fix issue where a useless error would be printed to the log and bad memory reads could occur when compiling a CON script with an invalid structure member passed as gamevar structure access shortcut shorthand

CON access to raw q16 values for player horiz and ang etc

Add EVENT_DISPLAYROOMSCAMERATILE

Fix CON commands leaving useless extra values in the bytecode. They were only valid outside of executable blocks so it was never noticed.

Fix CON compiler line number accounting problem introduced with the optimization that transforms CON_SETVARVAR -> CON_SETVAR if the second parameter is a constant

After some refactoring, several CON error checks done at runtime stood out as things that could be determined at script compile time. They have been moved.

Attempting to compile a CON with something stupid like "mul var 0" or "div var 0" in it now throws an error

Comment out actor and player versions of gamevar manipulation opcodes as they aren't performant with our current switch-based method of processing instructions. This also tweaks the beginning of VM_Execute() to gain a little more performance.

CON syntax extension: the empty "[]" shortcut for accessing a struct at index THISACTOR can now be omitted.

Misc CON fixups

Minor CON compiler cleanup

Direct struct access for tsprite, and break special gamevar access out of Gv_GetVar() and into a separate function like it already was with Gv_GetVarX()

gamedef.cpp and friends: use preprocessor defines instead of hard-coded values for gamevar IDs that are really constants or arrays or structs

CON structure member access readability cleanup

Add per-sound volume support to audiolib. This allows you to control the volume of sounds independently from the distance-based system exposed through CON. To use this, you must define your sounds via the .def syntax and set the "volume" property--default is 1.0.

Tweak gamevar struct shortcut error handling

Prevent OOB array access when EVENT_INVENTORYLEFT or EVENT_INVENTORYRIGHT returns a bad value

Remove compiled CON script from savegames in favor of storing a simple CRC32 value computed from the uncompiled CON text--this means that savegames can now only be loaded if the currently loaded CONs match what was in use when the game was saved.
