mesa: change ctx->Driver.ProgramStringNotify() to return GLboolean
GL_TRUE indicates that the driver accepts the program.
GL_FALSE indicates the program can't be compiled/translated by the
driver for some reason (too many resources used, etc).
Propogate this result up to the GL API: set GL_INVALID_OPERATION
error if glProgramString() was called. Set shader program link
status to GL_FALSE if glLinkProgram() was called.
At this point, drivers still don't do any program checking and
always return GL_TRUE.
