8b477463d1 Fix #33411: Smoke simulator using uninitialized noise tile 
If loading an existing FFT noise tile failed the tile in memory was left uninitialized.

2b962212c8 Fix #33411: crash baking smoke with FFT high resolution. 
CMake had FFTW disabled by default, and when FFTW was not enabled it lead to
uninitialized memory usage. Now it falls back to wavelet if there is no FFTW,
and I've enabled it by default in CMake. If it's not found on Linux it will get
disabled automatically.

1e13168183 Smoke: 
a) Another boundary fix. Resulted in smoke getting "sucked" back into the domain
b) Disabling substeps (internal thing). Fixes arbitrary explosions/instabilities.

f883d12e0c Smoke: Start fixing scaling issues which happen with non cube-shaped domains. 
Detail: Smoke solver and Blender side of smoke now share the same cell length.

First reported by the Sintel artists long ago, again reported by MiikaH.

8bf8a128c2 Smoke: Support for moving obstacles. (Merge from Smoke2 branch) 
Sponsored by the Blender Development Fund.
http://www.blender.org/blenderorg/blender-foundation/development-fund/

Remarks:
The original code was not designed to support moving obstacles so I had to introduce some velocity constraints into the code to prevent smoke from exploding. If this causes problems with "fire" emulation, please let me know.

ccd31900ab Fix #27855: crash on enabling high resolution smoke. 
Wavelet tile generation code was reading outside of array bounds, and as a
result could give a noise.wavelets file with nan values. Now that problem
is fixed, and existing files with nan are ignored.

1bd0db59f4 use cmake defined names for jpeg, png, zlib and python libs, building on *nix with non-standard libjpeg/png/zlib locations was broken. 
in the case of python this makes it easier to move to find_package(PythonLibs) when 3.x is supported.

e8397e6193 include headers in cmake source, added a script to check for consistency, reporting missing headers & C files. 
this is important so IDE's using CMake integration always get blender headers. - QtCreator & MSVC for eg, probably others too.

78cd971bac - smoke wasn't closing the file of loading a tile had the wrong length. 
- missing break in operator context switch meant RGN_TYPE_CHANNELS was always being overwritten with RGN_TYPE_PREVIEW when calling operators (from r26692)
