This effectively ends support for 32-bit Intel Macs. It switches the standard library to libc++, allowing us to use features from C++11.
There are some known bugs with older versions of libc++ (such as the istream::eof() bug); we may end up raising the minimum further (eg. to 10.9) soon if the situation becomes untenable.
Fixes#300
This back-end has been deprecated by Apple for a while, and has not been used in Panda. As we will no longer be supporting 32-bit macs going forward, and the Carbon windowing API is not available for 64-bit mac, there's no point in keeping it.
Apparently eof() in older versions of libc++ returns true if the last character has just been read, whereas the proper behavior is only to return true when attempting to read past the end of the stream. Since failbit is reliably set in all cases when reading past the length of the stream, we should only trust the result of eof() if fail() also returns true.

Specifically, this happens if you have a custom ShaderGenerator that assigns shader inputs via the ShaderAttrib. If two objects then both have the auto-shader turned on, and the shader generator generates ShaderAttribs with the same shaders but different inputs, the inputs will not be updated properly for one of the objects.
Generators can no longer raise StopIteration, and we are supposed to use "return" instead. But, return with value inside generator is a syntax error in Python 2.
Fixes#513
SimpleHashMap has a constexpr default constructor, so there is no static init ordering issue that requires us to allocate the states maps on the heap and then to leak them.
Also moves panda3d.dist-info directory to /Developer/Panda3D/ so that deleting /Developer/Panda3D makes it possible to install panda3d via pip again.
Fixes#502
