MEDIUM: connection: add new bit in Proxy Protocol V2
There are two sample commands to get information about the presence of a
client certificate.
ssl_fc_has_crt is true if there is a certificate present in the current
connection
ssl_c_used is true if there is a certificate present in the session.
If a session has stopped and resumed, then ssl_c_used could be true, while
ssl_fc_has_crt is false.
In the client byte of the TLS TLV of Proxy Protocol V2, there is only one
bit to indicate whether a certificate is present on the connection. The
attached patch adds a second bit to indicate the presence for the session.
This maintains backward compatibility.
[wt: this should be backported to 1.5 to help maintain compatibility
between versions]
