* c-exp.y (exp:STRING): Convert C strings into array-of-char

Browse Source 
constants with an explicit null byte terminator.  OP_STRING is
	now used for real string types.
	* c-lang.c (builtin_type_*):  Move declarations to lang.c since
	they are used by all languages.
	* c-lang.c (_initialize_c_language):  Move initializations of
	builtin_type_* to lang.c.
	* c-typeprint.c (c_type_print_varspec_prefix,
	c_type_print_varspec_suffix):  TYPE_CODE_PASCAL_ARRAY renamed
	to TYPE_CODE_STRING.
	* c-valprint.c (c_val_print):  Change the way character arrays
	are printed as strings to be consistent with the way strings
	are printed when pointer-to-char types are dereferenced.
	Remove test of print_max before calling val_print_string, which
	now does it's own test.
	* eval.c (evaluate_subexp):  Add case for OP_ARRAY.
	* expprint.c (print_subexp, dump_expression):  Add case for OP_ARRAY.
	* expression.h (enum exp_opcode):  Add OP_ARRAY and document.
	* gdbtypes.c (builtin_type_*):  Add declarations moved from
	c-lang.c.
	* gdbtypes.c (create_string_type):  New function to create real
	string types.
	* gdbtypes.c (recursive_dump_type):  TYPE_CODE_PASCAL_ARRAY
	renamed to TYPE_CODE_STRING.
	* gdbtypes.c (_initialize_gdbtypes):  Add initializations of
	builtin_type_* types moved from c-lang.c.
	* gdbtypes.h (enum type_code):  TYPE_CODE_PASCAL_ARRAY renamed
	to TYPE_CODE_STRING.
	* gdbtypes.h (builtin_type_string):  Add extern declaration.
	* gdbtypes.h (create_string_type):  Add prototype.
	* m2-lang.c (m2_create_fundamental_type):  TYPE_CODE_PASCAL_ARRAY
	renamed to TYPE_CODE_STRING.
	* m88k-tdep.c (pushed_size):  TYPE_CODE_PASCAL_ARRAY renamed to
	TYPE_CODE_STRING.
	* mipsread.c (_initialize_mipsread):  TYPE_CODE_PASCAL_ARRAY
	renamed to TYPE_CODE_STRING.
	* parse.c (length_of_subexp, prefixify_subexp):  Add case for
	OP_ARRAY.
	* printcmd.c (print_formatted):  Recognize TYPE_CODE_STRING.
	* typeprint.c (print_type_scalar):  TYPE_CODE_PASCAL_ARRAY renamed
	to TYPE_CODE_STRING.
	* valops.c (allocate_space_in_inferior):  New function and
	prototype, using code ripped out of value_string.
	* valops.c (value_string):  Rewritten to use new function
	allocate_space_in_inferior, but temporarily disabled until some
	other support is in place.
	* valops.c (value_array):  New function to create array constants.
	* valprint.c (val_print_string):  Add comment to document use,
	complete rewrite to fix several small buglets.
	* value.h (value_array):  Add prototype.
	* value.h (val_print_string):  Change prototype to match rewrite.
	**** start-sanitize-chill ****
	* ch-valprint.c (chill_val_print):  Add case for TYPE_CODE_STRING.
	* ch-exp.y (match_character_literal):  Disable recognition of
	control sequence form of character literals and document why.
	**** end-sanitize-chill ****
