Parse Signature Algorithm ext when renegotiating

Browse Source 
Signature algorithm extension was skipped when renegotiation was in
progress, causing the signature algorithm not to be known when
renegotiating, and failing the handshake. Fix removes the renegotiation
step check before parsing the extension.

Bugfix
* Parse signature algorithm extension when renegotiating. Previously,
renegotiated handshakes would only accept signatures using SHA-1
regardless of the peer's preferences, or fail if SHA-1 was disabled.
