Support both DSA and SSO variants of glProgramUniform*(). Also added (currently disabled) ES implementation (provided by EXT_separate_shader_objects). Unfortunately it's not possible to reduce the function count, because ARB_separate_shader_objects and EXT_direct_state_access are completely independent. Also double uniforms are supported since GL 4.0 and SSO are since 4.1, so we can't omit old glUniform*() calls for doubles either.
