    libpayload: allow compression at file header level
    
    Decompression is handled transparently within cbfs_get_file_content:
    
    	const char *name = "foo.bmp";
    	void *dst = cbfs_get_file_content(media, name, type, NULL);
    
    To keep things consistent, a couple of API changes were necessary:
    - cbfs_get_file_content always returns a copy of the data, even for
      uncompressed files. It's the callers responsibility to free the
      memory.
    - same for cbfs_load_payload and cbfs_find_file.
    - cbfs_load_optionrom doesn't take a "dest" argument anymore but always
      returns a copy of the data, for compressed and uncompressed files.
      Like with cbfs_get_file_content, the caller is responsible to free it.
      It also decompresses based on extended file attributes instead of the
      cbfs_optionrom subheader that libpayload specified but that (AFAIK)
      nobody ever used, given that there's not even tooling for that.
