Fix access violation when parsing a corrupt IEEE binary.
PR binutils/21612
* libieee.h (struct common_header_type): Add end_p field.
* ieee.c (this_byte_and_next): Do not advance input_p beyond

(read_id): Check for a length that exceeds the remaining bytes in
the input buffer.
(ieee_seek): Initialise end_p.
(ieee_archive_p): Likewise.
