Regarding the fixed encoding of a (sub)packet length I suggest the
following approach (AFAIK it's used by most OpenPGP implementations):

	if (len < 192)
	{
		// one-octet length format
	}
	else if (len < 8384)
	{
		// two-octet length format
	}
	else
	{
		// four-octet length format with 0xFF prefix
	}

Recently, I the length encoding in LibTMCG/DKGPG for subpackets, where
it was previously a four-octet length format with 0xFF prefix.
