* c-exp.y, m2-exp.y (yyreds, yytoks): Remap like other yy* names.

	* c-exp.y, m2-exp.y (YYDEBUG):  Define if MAINTENANCE_CMDS is defined
	and YYDEBUG is not already defined.
	* c-exp.y (strncmp):  Replace throughout with STREQN, missed
	them during the previous replacements.
	* printcmd.c (_initialize_printcmd):  Update internal documentation
	for "set" command to note that the assignment syntax is language
	dependent.
	**** start-sanitize-chill ****
	* ch-exp.y (yyreds, yytoks):  Remap like other yy* names.
	* ch-exp.y (YYDEBUG):  Define if MAINTENANCE_CMDS is defined
	and YYDEBUG is not already defined.
	* ch-exp.y (GDB_REGNAME, GDB_LAST, GDB_VARIABLE, GDB_ASSIGNMENT,
	single_assignment_action): New terminals and nonterminal for gdb
	extensions to chill expression grammer.
	* ch-exp.y (match_dollar_tokens):  Lexer routine to match all
	tokens that start with '$' (register names, convenience vars, etc).
	* ch-exp.y (tokentab2):  Add GDB_ASSIGNMENT.
	* ch-exp.y (yylex):  Call match_dollar_tokens.
