This reverts commit 0bfff783088f35a2962f7c955b4818a45c396b2a.
[TEXTURE_CACHE] *incompatible* Isolate texture cache queue and push/pop EAGLContext in sync operations
[TEXTURE] Fix compiler warning
[ASSERT] Fix crappy side-effects in the volatile NSAssert macro
[DEVICE] Remove pessimistic synchronization in fenceSync (legacy of debugging some synchronization issues)
[BINDABLE] Macro version of binding block syntax, depends on GCC extension
[TEXTURE] Macro version of block syntax for mapped buffer, depends on GCC extension
[BUILD] Prefer macro version of block syntax. Fix some compiler warnings in release mode
[DEVICE] Now I doubt strongly glFence* API is thread-safe, at least in iOS6. Lock the object again. Performance penalty is negligible anyway
[PODSPEC] v0.2.0
Merge branch 'texture_cache_context'
