ARB prog: Change handling of program parameter limits
Several changes are made to program parameter limits. Several of the non-NATIVE limits are set higher. All of the NATIVE limits are set to zero in the core Mesa code. Each driver must set the actual value in its context creation routine. If the NATIVE value remains zero, this indicates that hardware shaders may not be supported. Each of the preceeding changes matches the bahavior of Apple's shader assembler, so it seems safe. Finally, we limit the value of MaxEnvParams to be no greater than MaxNativeAttribs. At least one case has been found where an application does the wrong thing if MaxNativeAttribs < MaxEnvParams. See also bugzilla #23490.
