If East Asian people were unable to see the Latin characters, it becomes a barrier to mutual understanding. FontLink will break that barrier. JIRA issue: CORE-9616 JIRA issue: CORE-15480 - Modify font substitutes. - Unify the lock variables. - Add FONTLINK and FONTLINK_CHAIN structures. - Add FontLink_Create and FontLink_Destroy functions. - Add FontLink_Chain_Init, FontLink_Chain_Free, FontLink_Chain_LoadReg, FontLink_Chain_Populate, and FontLink_Chain_FindGlyph functions. - Implement FontLink. - Add font file DroidSansFallback.ttf for LiveCD.
