readelf: Handle compressed sections and extend -z to cover -x and -p.
When printing a (non-string, non-data) section use uncompressed data when possible. For dumping hex and string sections (-x and -p) -z will dump the uncompressed data (otherwise the compressed data is dumped). -z, --decompress Show compression information for compressed sections (when used with -S); decompress section before dumping data (when used with -p or -x) Includes test cases for ET_REL files using compressed relocation (target) debug sections to test libdwfl transparent uncompression of sections.
