There's one thing we didn't foresee from the beginning,
which is apparently TLS is only available in OSX starting
from version 10.7, and we still do support of 10.6.
After recent Brecht's changes about locked viewport
while initializing BI render this TLS is not needed
in trunk anymore. So reverting this chunk of base
iteration to use static variable. But leaving all the
other static variables warped into context still, it
should help a bit in the future refactor.
Real fix would be to have some kind of graph context
evaluation structure which would be passing to update
routines (which will solve threaded mballs update) and
making depsgraph responsible for getting a motherball.
But this is all for GSoC project.

This time issue was caused by static variables used in
BKE_scene_base_iter_next function.
Change is not so much ultimate actually, but didn't
find more clear solution for now. So the changes are:
- Wrap almost all the static variables into own context-
like structure, which is owned by the callee function
and getting passed to the iteration function.
- Recursion detection wasn't possible with such approach,
so recursion detection still uses static in_next_object
variable, but which is now stored in thread local
storage (TLS, or thread variable if this names are more
clear for you).
This makes code thread-safe, but for sure final solution
shall be completely different. Ideally, dependency graph
shall be possible to answer on question "which object is
a motherball for this metaball". This will avoid iterating
via all the bases, objects and duplis just to get needed
motherball.
Further, metaball evaluation ideally will use the same
kind of depsgraph filtering, which will get result for
question like "which objects belongs to this group of
metaballs".
But this ideal things are to be solved in Joshua's and
mind GSoC projects.
Tested on linux (gcc and clang) and windows (msvc2008),
hopefully no compilation error will happen.
Thanks to Brecht for reviewing the change and getting
feedback for other possible ways we've dicussed!

the way Curve.len is used at the moment is really stupid, calculate string size on save for now, but should really store the length in bytes and total number of characters.

data.
Now the viewport rendering thread will lock the main thread while it is exporting
objects to render data. This is not ideal if you have big scenes that might block
the UI, but Cycles does the same, and it's fairly quick because the same evaluated
mesh can be used as for viewport drawing. It's the only way to get things stable
until the thread safe dependency graph is here.
This adds a mechanism to the job system for jobs to lock the main thread, using a
new 'ticket mutex lock' which is a mutex lock that gives priority to the first
thread that tries to lock the mutex.
Still to solve: undo/redo crashes.

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).

also change define checks in BLI_sys_types.h (was warning a lot in linux about unused defines).

VS 2010 and 2012 have stdint.h so we should use them for consistency instead of defining the inttypes ourselves.
Added if condition for for stdint.h include for >= VS 2010
P.S.: Compiled and tested on VS2008-2012 and MinGW with scons and CMake ;)

There were an issues with data structures defined in headers
and being used by both C and C++ on systems with stdbool
unavailable.
This happened because bool in this case will be defined as
unsigned int, which is 4 bytes. But C++'s bool is only 1
byte and this lead to alignment issues.
Now bool is always 1 byte, also made sure there's no situation
like bool foo = BitField & BitFlag, which could give overflow
issues. Use (BitField & BitFlag) != 0 instead.
