This makes the null platform behave more like an actual stub. More
queryable state is tracked and there is even a fake monitor with one
whole fake video mode.
Inclusion of internal headers is already both centralized and follows
strict rules. Inclusion guards are both an unneccessary maintenance
burden and may hide inclusion order bugs.
Fixes formatting, semantics and documentation. Adds
glfwGetOSMesaContext. Adds support for OSMesa context attributes.
Updates changelog and credits. Adds license and copyright headers.
Removes superfluous code (the shared code provides many conveniences).
Removes loading of unused OSMesa functions. Removes empty platform
structs. Fixes version string format. Removes build dependency on
the OSMesa header and library (only the library is needed and only at
runtime).
Closes#850.
