Fix ssl to decode http packets in the same way as gen_tcp

[Rory Byrne]

Hi,

   git fetch git://github.com/jinsky/otp.git ssl_decode_http_packet_fix

This updates ssl to behave in the same way as gen_tcp when it's given
the {packet,http} option. It will now automatically switch to expect 
HTTP headers after it receives a HTTP Request or HTTP Response line.

Cheers,

Rory
