This makes it possible to include it multiple times in a single
translation unit, and/or multiple times in a single dynamic
library (and without excess code bloat, too).
Newer versions of FFmpeg deprecate returning 0 to indicate
EOF, and instead request use of AVERROR_EOF.
The oldest supported versions of FFmpeg/libav will treat any
error code the same as returning 0.
Fixes#315
This comes up when building with DEBUG_THREADS; there is a PipelineCycler created at static init time, and the type tracking in Pipeline won't work properly if the CData's parent's TypeHandle has not yet been initialized.
There is a bug in clang versions before 3.2 (including the one shipped with Xcode) that makes it give a "conflicting types" compile error when there is a static constexpr function defined outside the class. The way to work around this is either to remove one of the "static" or "constexpr" keywords, or to simply put the definition inline.

I would try and upgrade Xcode to version 5 to see if the problem is fixed, but the buildbot still runs OS X Lion (10.7) and the last version of Xcode that works on Lion is 4.6.3, so it seems easier to just apply these workarounds for now.
This renames acquire/release to lock/unlock in order to be compatible with std::lock_guard and std::unique_lock (which will eventually replace the *MutexHolder classes). It will also allow us to typedef MutexImpl to std::mutex later on.
To access a WeakPointerTo in a thread-safe way, use something like this:
if (auto ptr = weak_ptr.lock()) {
..use ptr as regular PointerTo
}
The new implementation no longer needs a reference to be stored to all weak pointers on the WeakReferenceList; a mere count of weak pointers is sufficient. Therefore, callbacks theoretically no longer require a WeakPointerTo to be constructed.
The WeakPointerTo class is not actually atomic; it could be made so, but I don't believe it's worth it at this time.
This allows using a coroutine to build up a more complex sequence including transitions (eg. scripted cutscene), as well as provide a standard way to register callbacks upon completion of the transition.
We don't guarantee a specific order in this case, especially because they can be run in either order if there is more than one thread, but it is still useful to have a defined order for single-threaded task chains. To that end, tasks
are now run in the order in which they were added to taskMgr.add (in absence of any other ordering constraints).
Fixes#309
These were removed by 88dbb31daa02779405ef5326677eefb5cf93f3c8 under the assumption that they were not used, but it has recently come to my attention that there is still code out there that uses these.
PriorityCallbacks has been updated to be compatible with Python 3 by only comparing the priority, rather than the (priority, callback) tuple. This also has the side-effect of ditching the bisect dependency.
Also moves testing code from the source to the unit tests.
- Release the global lock during the user tick callback
and allow interactions with bullet world
- Acquire the lock again after the callback

I have no idea why this error happens, but it does not seem worth the effort to investigate further, so I'm just reverting the previous change to this file.
