Added Message Stream Encryption(MSE) support.
	Currently, aria2 accepts incoming connections with Obfuscation Header
	and legacy BitTorrent Header and establishes connections with
	Obfuscation Header first and if failed then retry with legacy
	BitTorrent header. If plain text and ARC4 is provided, aria2 always
	choose ARC4. The new option to change the default behavior is planned.
	For tracker extension, "supportcrypto=1" is added statically.
