More use of bool type, necessitating adding inclusion of BLI_utildefines.h, or moving it up in the inclusion order if it was already included, in various places
- storage.c: make some variables only used in bli_builddir local to that
- storage.c: BLI_file_descriptor_size should allow 0 as a valid file descriptor
- path_util.c: make pointers to non-reentrant storage returned from folder routines const, necessitating making variables holding these returned pointers const elsewhere as well
- path_util.c: BLI_string_to_utf8 closes iconv context in case of conversion error
- blf_lang.c: fill_locales routine now has its own "languages" local variable to construct paths (was stealing internal storage belonging to BLI_get_folder before)
The problem is that, when HAVE__BOOL is not defined (as it is the case in scons currently), BLI_utildefines.h defines bool as a standard type. Was using signed char, which makes eg "bool foo = 1024" be false (overflow)! Especially nasty when using bitflags (think we have been lucky to not have worse bugs because of that)!
So changed fallback bool type to unsigned int.
Looks like _Bool is also a type in std (at least with msvc), so the 'typdef bool _Bool;' generates a name collision... Now using _BLI_Bool as placeholder instead.

so BKE_utildefines.h allows use of C99's bool type and true/false.
currently scons wont try to use stdbool.h, and works as if its never found.
- use unsigned ints only (where mixing signed/unsigned)
- turn heap_swap into an inline function, add SWAP_TVAL macro to swap values using a temp value as storage.
- added type checking SHIFT3/4 macros
also style cleanup for CTR_Map

Its unlikely you want to do short -> int, int -> float etc, conversion during swapping (if its needed we could have a non type checking macro).
Double that the optimized assembler outbut using SWAP() remains unchanged from before.
This exposed quite a few places where redundant type conversion was going on.
Also remove curve.c's swapdata() and replace its use with swap_v3_v3()
made some small edits
- removed changes to AVI reading since the data types are apart of the format spec.
- absf -> abs for a double value in render code.
* Accelerated sRGB <=> linear conversion using lookup table, this can speed up
loading of images in the compositor and simple renders quite a bit.
* Dithering now uses the Floyd-Steinberg algorithm. Previously it would simply
randomize each pixel slightly, adding noise, now that should be reduced.
Patch #29309 by David M.
- removed AVG2, was only used once.
- remove unused LONGCOPY define.
- removed BLI_STRUCT_OFFSET, was only used once, replce with offsetof
- formatting edits, split some macros over multiple lines.
- rename define DISABLE_SDL --> WITH_SDL (which was already used in some places)
- blenders interation preset was using orbit rather then turntable 3d view preference (different from factory defaults).
- tagged some unused rna args.
- define __BIG_ENDIAN__ or __LITTLE_ENDIAN__ with cmake & scons.
- ENDIAN_ORDER is now a define rather than a global short.
- replace checks like this with single ifdef: #if defined(__sgi) || defined (__sparc) || defined (__sparc__) || defined (__PPC__) || defined (__ppc__) || defined (__hppa__) || defined (__BIG_ENDIAN__)
- remove BKE_endian.h which isn't used
This fix also allows for partial update of the image, speeding up painting.
The different code path implemented will be used to upload high resolution images to OpenGL when onion branch is merged.
Due to conversion of float textures to/from sRGB, corrections made to brush color sampling to take account of the image profile. This is not 100% correct yet as texture images used for projection painting strokes are not converted to/from sRGB yet(This has been decided due to loss of precision for 8-bit formats). It will have to do for now, though.
last-minute update, exr image loading is broken, will fix asap
