* vms-alpha.c (parse_module): Make length param bfd_size_type.
Delete length == -1 checks.  Sanity check record_length.
Sanity check DST__K_MODBEG, DST__K_RTNBEG, DST__K_RTNEND lengths.
Sanity check DST__K_SOURCE and DST__K_LINE_NUM elements
before accessing.
(build_module_list): Pass dst_section size to parse_module.
