ClientHello Padding for Fast Radio Opening in 3G.

The ClientHello record is padded to 1024 bytes when
fastradio_padding is enabled. As a result, the 3G cellular radio
is fast forwarded to DCH (high data rate) state. This mechanism
leads to a substantial redunction in terms of TLS handshake
latency, and benefits mobile apps that are running on top of TLS.
