  * src/otlayout/otcommn.c: Use OTL_CHECK everywhere. (otl_coverage_validate): Initialize `p', s/count/num_glyphs/. s/start_cover/start_coverage/. (otl_coverage_get_index): Return OTL_Long, not OTL_Int. Remove unused variables. (otl_class_definition_validate): s/count/num_glyphs/. Remove unused variables. (otl_class_definition_get_value, otl_device_table_get_start, otl_device_table_get_end, otl_device_table_get_delta, otl_lookup_get_table, otl_lookup_list_get_count, otl_lookup_list_get_lookup, otl_lookup_list_get_table, otl_feature_get_lookups, otl_feature_list_get_count, otl_feature_list_get_feature, otl_lang_get_count, otl_lang_get_req_feature, otl_lang_get_features): Commented out temporarily until we really need it. (otl_lookup_validate): Removed. (otl_lookup_table_validate): Renamed to ... (otl_lookup_validate): This. Update callers. (otl_lookup_list_validate): Remove already commented out definition and move the other definition up. (otl_feature_validate): Add parameter to pass number of lookups. Update callers. Check lookup indices. (otl_feature_list_validate): Add parameter to pass lookup table. Update callers. (otl_lang_validate): Add parameter to pass number of features. Update callers. Handle req_feature and check feature indices. (otl_script_validate): Add parameter to pass number of features. Update callers. (otl_script_list_validate): Add parameter to pass feature table. Update callers. * src/otlayout/otcommn.h: s/LOCALDEF/LOCAL/. Comment out the same functions as in otcommn.c. (otl_script_list_get_script): Removed. * src/otlayout/otlgsub.c (otl_gsub_lookup1_apply): Change `index' to type OTL_Long. (otl_gsub_lookup2_apply, otl_gsub_lookup3_apply): Change `index' to type OTL_Long. Fix test. (otl_gsub_validate): Fix order of validation. * src/otlayout/otlgpos.c (otl_gpos_validate): Fix order of validation.
