l_tls_set_auth_data/l_tls_set_cacert both expected file paths to be
passed in, and the certs/keys would be loaded internally. This prevents
the caller from loading certs any way but from files. This makes
loading certs/keys from data impossible if using TLS. For example,
a certificate may be embedded inside a file which has additional data.
To handle both file/data cases its now up to the caller to load the
cert/key as an l_cert/l_certchain/l_key/l_queue and pass that structure
in directly.
The structure being passed in will now be owned by l_tls, and will be
freed on l_tls_free.

l_pem_load_certificate_list returns a queue of l_certchains and
cleaning up this queue requires l_certchain_free to be wrapped
in a queue destroy function.
This patch changes l_certchain_free to take a void * so it can
be used directly in l_queue_destroy.
