Don't add the zlib header to SHF_COMPRESSED section
In a SHF_COMPRESSED compressed section, the raw compressed data should
begin immediately after the compression header. This patch removes the
extra zlib header from the SHF_COMPRESSED section.
bfd/
* bfd.c (bfd_update_compression_header): Also write the zlib
header if the SHF_COMPRESSED bit cleared..
(bfd_check_compression_header): Return the uncompressed size.
* compress.c (decompress_contents): Don't skip the zlib header.
(bfd_compress_section_contents): Properly handle ELFCOMPRESS_ZLIB,
which doesn't have the zlib header.
(bfd_init_section_decompress_status): Likewise.
(bfd_get_full_section_contents): Updated.
(bfd_is_section_compressed): Likewise.
(bfd_is_section_compressed_with_header): Return the uncompressed
size.
* elf.c (_bfd_elf_make_section_from_shdr): Updated.
* bfd-in2.h: Regenerated.
binutils/
* readelf.c (uncompress_section_contents): Add a parameter for
uncompressed size. Don't check the zlib header.
(load_specific_debug_section): Updated.
binutils/testsuite/
* binutils-all/compress.exp: Replace "$OBJDUMP -s -j .debug_info"
with "$OBJDUMP -W".
* binutils-all/libdw2-compressedgabi.out: Updated.

* write.c (compress_debug): Don't write the zlib header, which
is handled by bfd_update_compression_header.
