* ssl-verify-host: fix verifying ip addresses containing zero's
If the subject alternate name contained an ip address with an zero
(like 10.42.0.1) it could not successfully verify.
It is because in c++ strings are null-terminated
and therefore strlen(name) would return a wrong result.
As I can not see why we can not trust the length returned by openssl,
lets drop this check.
* ssl-verify-host: add test case
lets try to validate against 127.0.0.1

In case we want to send a lot of data,
and the receiver is slower than the sender.
This will first fill up the receivers queues and after this
eventually also the senders queues,
until the socket is temporarily unable to accept more data to send.
select_write is done with an timeout of zero,
which makes the select call used always return immediately:
(see http://man7.org/linux/man-pages/man2/select.2.html)
This means that every marginal unavailability will make it return false
for is_writable and therefore httplib will immediately abort the transfer.
Therefore make this values configurable in the same way
as the read timeout already is.
Set the default write timeout to 5 seconds,
the same default value used for the read timeout.
According to RFC 3493 the socket option IPV6_V6ONLY
should be off by default, see
https://tools.ietf.org/html/rfc3493#page-22 (chapter 5.3).
However this does not seem to be the case on all systems.
For instance on any Windows OS, the option is on by default.
Therefore clear this option in order to allow
an server socket which can support IPv6 and IPv4 at the same time.
* SSLServer: add constructor to pass ssl-certificates and key from memory
* SSLClient: add constructor to pass ssl-certificates and key from memory
* add TestCase for passing certificates from memory to SSLClient/SSLServer
