This patch aims at providing multiple compression modes for TIFF output,
particularly uncompressed mode.
At this moment have None, Deflate, LZW and Pack Bits modes been integrated,
mimicking The GIMP export modes (except JPEG mode, which returned encoding
errors).
More modes could be added if needed.
Default remains Deflate.

Screenshot ignored errors, some render code printed 'Saved' without checking for failure.
note: errno is now cleared from IMB_saveiff so all callers don't need to.

While SCons building system was serving us really good for ages it's no longer
having much attention by the developers and started to become quite a difficult
task to maintain.
What's even worse -- there started to be quite serious divergence between SCons
and CMake which was only accumulating over the releases now. The fact that none
of the active developers are really using SCons and that our main studio is also
using CMake spotting bugs in the SCons builds became quite a difficult task and
we aren't always spotting them in time.
Meanwhile CMake became really mature building system which is available on every
platform we support and arguably it's also easier and more robust to use.
This commit includes:
- Removal of actual SCons building system
- Removal of SCons git submodule
- Removal of documentation which is stored in the sources and covers SCons
- Tweaks to the buildbot master to stop using SCons submodule
(this change requires deploying to the server)
- Tweaks to the install dependencies script to skip installing or mentioning
SCons building system
- Tweaks to various helper scripts to avoid mention of SCons folders/files
as well

The issue was caused by the image save operator ignoring Z-Buf if the input
buffer due to the way how IMB_dupImBuf() worked. There's no reason to to
ignore z-buf on imbuf duplication, it only asks for issues in the future.

image data
If the node output had only one layer, it would be detected as singlelayer, and it would miss the blender exr header string
|

`size_t` is useful for memory sizes or offsets,
the number of views wont realistically exceed an int.

This is a feature unique to jpeg that would store the quality it was saved.
- Use struct instead of bit-shifting.
- No longer store the 'flag'.

mode (fonts, images...).
Windows-only bug, mmap & co are not threadsafe by default on this platform, so we have to add a dedicated
spinlock for them in win32.
Note that we may try to get rid of those mmap later, but not for 2.76!
To be backported to final 2.76...

In fact, any user of IMB_scalefastImBuf() is now robust against working
with really hires images.

them when reading in background mode.
Primary goal of this commit is to fix an annoying issue - when processing and saving .blend
files in background mode you lose their thumbnails, since it can only be generated with
an OpenGL context.
Solution to that is to read .blend thumbnail while reading .blend file (only done in background
mode currently), and store it in Main struct.
Also, this lead to removing .blend file reading code from thumb_blend (no need to have doublons).
We now have a small interface in regular reading code area, which keeps it reasonbaly light
by only reading/parsing header info, and first few BHead blocks.
This makes code reading .blend thumbnail about 3 to 4 times slower than previous highly specialized
one in blend_thumb.c, but overall thumbnail generation of a big .blend files folder only grows
of about 1%, think we can bare with it.
Finally, since thumbnail is now optionally stored in Main struct, it makes it easy to allow user
to define their own custom one (instead of auto-generated one). RNA API for this was not added though,
accessing that kind of .blend meta-data has to be rethought a bit on a bigger level first.

.blend file.
Notes:
* Not yet used, this is the last piece of 'side changes' before the big filebrowser commit.
* We can probably be more effective here (like e.g. reading and storing all previews for a given
group in thumbnails cache at once, instead of re-opening and parsing the whole file each time),
but will do this later.

General idea is that, if several threads are handling thumbnails at the same time,
they can end working on the same file at some point, which will generate conflict.
To avoid this, threads can now lock a given filepath.
Note that locking data is allocated on a ref-count basis, to avoid keeping the GSet
in memory when not needed. Also, we are using global LOCK_IMAGE mutex for now.
Needed for upcomming filebrowser rework.

- Add blentranslation `BLT_*` module.
- moved & split `BLF_translation.h` into (`BLT_translation.h`, `BLT_lang.h`).
- moved `BLF_*_unifont` functions from `blf_translation.c` to new source file `blf_font_i18n.c`.

- Fixed crash loading multilayer EXR
- Fixed another memory leak loading multilayer EXR

Issue was that with those files, Blender generate a float image by default, not a byte one...
Now, we ensure in two places we only get a byte imbuf for our thumbnails!

ImBuf types were getting stored as bitflags in a 32bit integer which had
already run out of space. Solved the problem by separating file type to
an ftype enum, and file specific options to foptions.
Reviewed by Campbell, thanks a lot!

Older libpng library does not use const pointer to a memory.
The exact version is a bit of a guess here, maybe needs tweaks to it tho.

PNG_COLOR_TYPE_GRAY colortype can have some values for alpha, in the same way as
PNG_COLOR_TYPE_PALETTE colortype.
In this case, we need two channels (grayscale and alpha), not one.
