the distance checks could get into a feedback loop so that the result depended on the order of verts/edges.
now you can randomize vert/edge/faces and get exactly the same results.
also made some internal improvements,
- used fixed sized arrays (no need to realloc).
- use vertex tag flags rather then a visit-hash.
- remove 'tots' array that did nothing (not sure why it was added).

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.
