libsframe: fix cosmetic issues and typos

include/
	* sframe-api.h (sframe_decoder_get_num_fidx): Use extern.
libsframe/
	* sframe-dump.c (dump_sframe_func_with_fres): Fix line length.
	* sframe.c (sframe_frame_row_entry_copy): Likewise.
	(sframe_decode_fre_start_address): Use the intended type uint32_t.
