Simplify ctx->_NumColorDrawBuffers, _ColorDrawBuffers and fix bug 13835.
These fields are no longer indexed by shader output. Now, we just have
a simple array of renderbuffer pointers.
If the shader writes to gl_FragData[i], send those colors to the N
_ColorDrawBuffers. Otherwise, replicate the single gl_FragColor (or
the fixed-function color) to the N _ColorDrawBuffers.
A few more changes and simplifications can follow from this...
