Update from version 4.65 (2009) to latest 23.01 (2023).
LZMA is only used for pointcache "Heavy" compression option. With
updated SDK, testing in a 100k particle system point cache
(Windows/Ryzen5950X), average times to read or write a cached frame:
- Read a bit faster, 24.3 -> 23.2ms
- Write/bake about 2x faster, 237 -> 103ms

This mainly touches extern libraries and few debug-only places in intern.
Some summary:
- External libraries are not strict at all about missing declarations,
so we can rather safely remove such warning together with other strict
flags.
- Bullet has some static functions which are not used.
Those were commented out.
- Carve now has some unused debug-only functions commented out as well.
While we're on the way of getting rid of Carve, it makes sense to make
things a bit cleaner for the time being.
- In LZMA we have some parts disabled which gives some set but unused
variables which is rather correct.
- Elbeem had quite some variables set and never used because their usage
is inside of debug-only code which is commented out.
Note about patching upstream libraries: surely one might say that we
have to make local patchset against this, but own experience says it
only gives extra work trying to merge such tweaks to a new upstream
version and usually it's just faster to re-apply such fixes again after
bundling new upstream library.
* cache for low res (deactivating high res for now)
* new way of view3d rendering of smoke (no longer 3 axes) -using 3dtexture now (introduced into gpu/intern)
* introducing LZO and LZMA libs into extern (makefiles missing for now)
* reducing memory usage after simulating for the frame ended (freeing temporary buffers)
* splitting smoke into 2 modifier for the cache-sake (it cannot handle more than 1 cache on the same modifier-index)
* no color on gui anymore
* fixing non-power-of-2 resolutions (hopefully)
* fixing select-deselect of domain drawing bug
* fixing drawobject.c coding style (making Ton happy) ;-)
HINT #1: If scons doesn't work -> cmakefiles are up-to-date, couldn't test scons (but i tried to mantain them, too)
CODERS HINT #1: we really need a way to disable adding all modifiers through "Add Modifiers" dropdown!
WARNING #1: before applying this commit, deactivate your SMOKE DOMAIN in your old files and save them then. You can open them then savely after that.
WARNING #2: File and cache format of smoke can be changed, this is not final!
