+ Remove nested functions from script reading and parsing.
+
+ * grub-core/kern/parser.c (grub_parser_split_cmdline): Add
+ getline_data argument, passed to getline.
+ * grub-core/kern/rescue_parser.c (grub_rescue_parse_line): Add
+ getline_data argument, passed to grub_parser_split_cmdline.
+ * grub-core/script/lexer.c (grub_script_lexer_yywrap): Pass
+ lexerstate->getline_data to lexerstate->getline.
+ (grub_script_lexer_init): Add getline_data argument, saved in
+ lexerstate->getline_data.
+ * grub-core/script/main.c (grub_normal_parse_line): Add getline_data
+ argument, passed to grub_script_parse.
+ * grub-core/script/script.c (grub_script_parse): Add getline_data
+ argument, passed to grub_script_lexer_init.
+ * include/grub/parser.h (grub_parser_split_cmdline): Update
+ prototype. Update all callers to pass appropriate getline data.
+ (struct grub_parser.parse_line): Likewise.
+ (grub_rescue_parse_line): Likewise.
+ * include/grub/reader.h (grub_reader_getline_t): Add void *
+ argument.
+ * include/grub/script_sh.h (struct grub_lexer_param): Add
+ getline_data member.
+ (grub_script_parse): Update prototype. Update all callers to pass
+ appropriate getline data.

+
+ * grub-core/commands/legacycfg.c (legacy_file_getline): Add unused
+ data argument.
+ * grub-core/kern/parser.c (grub_parser_execute: getline): Make
+ static instead of nested. Rename to ...
+ (grub_parser_execute_getline): ... this.
+ * grub-core/kern/rescue_reader.c (grub_rescue_read_line): Add unused
+ data argument.
+ * grub-core/normal/main.c (read_config_file: getline): Make static
+ instead of nested. Rename to ...
+ (read_config_file_getline): ... this.
