	* c-lang.c: Set case sensitivity on for c_language_defn,
	cplus_language_defn, and asm_language_defn.
	* ch-lang.c: Set case sensitivity on for chill_language_defn.
	* f-lang.c: Set case sensivitity off for f_language_defn.
	* jv-lang.c: Set case sensitivity on for java_language_defn.
	* language.h: Add enum case_mode, case_sensitivity.
	* language.c: Define case_mode, case_sensitivity.  Set case
	sensitivity on for unknown_language_defn, auto_language_defn,
	and local_language_defn.
	(show_case_command,set_case_command,set_case_str): New static func.
	(set_type_range_case): New static func, replaces set_type_range ().
	(set_language_command,set_type_command,set_range_command,set_language):
	Call set_type_range_case ().
	(language_info): Print case sensitivity setting.
	(_initialize_language): Add set/show commands for 'case-sensitive'.
	Set default case mode 'auto'.  Set default language 'auto'.
	* m2-lang.c: Set case sensitivity on for m2_language_defn.
	* p-lang.c: Set case sensitivity on for pascal_language_defn.
	* scm-lang.c: Set case sensitivity off for scm_language_defn.
	* symtab.c (lookup_symbol): Downcase symbol name if case sensivitity
	is off.
