lex.c (java_new_lexer): Initialize new fields.

	* lex.c (java_new_lexer): Initialize new fields.  Work around
	broken iconv() implementations.
	(java_read_char): Swap bytes if required.  Use fallback decoder if
	required.
	(byteswap_init, need_byteswap): New globals.
	(java_destroy_lexer): Only close iconv handle if it is in use.
	* lex.h (java_lexer): New fields read_anything, byte_swap,
	use_fallback.
	Made out_buffer unsigned.
