Andy Green 224149ab58 fix ssl reject path for freeing header allocation 
If the SSL connection failed before the headers came, we were not
dealing with deallocating the header malloc.  This takes care of it.

Using CyaSSL, we are then valgrind-clean for ssl client and server.

With OpenSSL, there is 88 bytes lost at init that never changes or
gets recovered.  AFAIK there's nothing to do about that.

OpenSSL also blows these during operation

However googling around

https://bugs.launchpad.net/ubuntu/+source/openssl/+bug/60021
http://www.openssl.org/support/faq.html#PROG13
(also the next FAQ down)

it seems OpenSSL have a relaxed attitude to this and it's expected.
It's interesting CyaSSL works fine but doesn't have that problem...
