    cbfstool: allow compression at file header level
    
    Currently, compression is only allowed at subheader level (e.g. cbfs_stage,
    cbfs_payload_segment). This change adds compression field to each file's
    header so that any cbfs file can be compressed.
    
    With the necessary additions in coreboot and libpayload, the following sample
    code can load a compressed file:
    
    	const char *name = "foo.bmp";
    	struct cbfs_file *file = cbfs_get_file(media, name);
    	void *dst = malloc(ntohl(file->uncompressed_size));
    	dst = cbfs_get_file_content(media, name, type, file, dst);
    
    cbfs_stage and cbfs_payload_segment continue to support compression at
    subheader level because stages and payloads have to be decompressed to the load
    address, which is stored in the subheader. For these, file level compression
    should be turned off.
