in src/client_side.cc:

* Please use "TLS" in debugs messages instead of "SSL".

* Please use "Tls" instead of "Ssl" in new symbol names such as the
handleIdleClientPinned***Read() method being added.

* Missing whitespace; "if(!ssl)" should be "if (!ssl)"

* Please use nullptr instead of NULL on new and altered lines.

* Please debug output the full pinning.serverConnection instead of just
the FD on debugs with levels higher than 1 / IMPORTANT.

in src/client_side.h:

* Please use "\returns" instead if "Returns" in the doxygen comment.

Since those are all cosmetic I dont think it needs another audit.

+1. Please apply once the polishing edits are done.
