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.

* Fix memory leak in mbedtls_ssl_set_hostname() when called multiple times.
Found by projectgus and jethrogb, #836.
* Fix usage help in ssl_server2 example. Found and fixed by Bei Lin.
* 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.
