Check file size before getting section contents
Don't check the section size in bfd_get_full_section_contents since the size of a decompressed section may be larger than the file size. Instead, check file size in _bfd_generic_get_section_contents. PR binutils/21665 * compress.c (bfd_get_full_section_contents): Don't check the file size here. * libbfd.c (_bfd_generic_get_section_contents): Check for and reject a section whoes size + offset is greater than the size of the entire file. (_bfd_generic_get_section_contents_in_window): Likewise.
