Changes:

• Reverted the changes to MenuEvents.inc done in r492 since they broke the F1 key function in XTIDECFG.
• Added a tail-call optimized variant of the CALL_DISPLAY_LIBRARY macro (JMP_DISPLAY_LIBRARY).
• Put a block size limit in AH1Eh_ChangeXTCFmodeBasedOnControlRegisterInAL. I think it's needed but if not, it's easy to remove.
• Other optimizations and fixes.
