Cosa è cambiato in EDuke32, build per build

In those Clang versions, -fcatch-undefined-behavior was replaced by -fsanitize=<what>. For Clang 3.2, we enable the address sanitizer and for 3.3 also the miscellaneous undefined behavior one. Currently, there's no version auto-detection from the Makefiles, it's set to 3.3 and the others are commented out.

Numbers 0 and 1 mean 'no spread', but the latter does one krand() call. Negative numbers are reserved for potential future use.

grpinfo { name "YourGameName" scriptname "yourgame.con" defname "yourgame.def" size yourgrpsize dependency DUKE15_CRC flags GAMEFLAG_ADDON crc yourgrpcrc } The "flags" field can also take the value "GAMEFLAG_DUKE" to define a new base game. Since this is the first commit of a new feature, certain semantics of the implementation and syntax are liable to change as necessary.

Set it to >=0 to override the base palette (water, slime, ...) in 3D mode. This can be useful to navigate Lameduke's underwater sections, since its LOOKUP.DAT only contains 8 lookup tables, but no other *base* palettes. Consequently, base palettes >=1 will make the whole screen black when Lameduke's LOOKUP.DAT is loaded into EDuke32 or Mapster32.

Also remove the two instances of commented out code, but not the respective CON structure access code.

- In the A_MoveSprite() code that transports projectiles due to an SE7 (introduced in r1450 / legacy ROR), only report "success" if the transportation succeeded. - Clear newly introduced internal SPRITE_DIDNOSE7WATER flag after checking it.

Also, in two cases, don't assign A_IncurDamage() result to a variable if it's not needed.

- In S_PlaySound(), move the sound index bound check above an indexing. - For A_CheckHitSprite(), and A_FindPlayer(), allow NULL second arg. - In A_ShootWithZvel(), make some one-letter vars be int32_t, making storing safeldist() results in them meaningful. - In MaybeTrainKillEnemies(), remove two redundant checks and move another one further up. - Comment that SIDEBOLT1 will never be translucent as was probably intended. - In G_MoveFX(), fix an always-true comparison.

- Rewrite some sprites-of-{stat,sector} loops using the SPRITES_OF, SPRITES_OF_SECT and new SPRITES_OF_SECT_SAFE macros. - In passing, identify some problems and mark them with 'XXX', but don't attempt to fix them yet. - The usual readability improvements...

Actually, the tweaked code in VM_Move() is not specific to projectiles, so other sprites now may pass no-SE7 water boundaries too, but it's most noticeable with projectiles.

That is, if submerging, the lower sector MUST have lotag 2. If emerging, the upper sector MUST have lotag 1. (Previously, emersion happened from ST 2 sectors unconditionally.) This means that the area where submersion or emersion can happen is now the same for the top and bottom parts.
