AmiSSL's approach to replacing 90% of OpenSSL calls with assembly
means that the official way to pop_free a stack type won't work.
As such, we open-code it here.

This simplifies the poll loops a little more and makes me less worried
that some other corner case will bite us in the future.

Because cURL can do connection caching behind the scenes, we
need to have a cache for the SSL certificate chains which we
send onward on first header back from cURL.
This uses the new hashmap implementation to mean that we cache
chains on a hostname:port basis.

Instead of extracting information from the X509 certificate chain in
the fetcher the entire chain is propagated in Distinguished Encoding
Rules (DER) format.
This allows all the information contained in a certificate chain to be
retained which can subsequently be presented to the user
* Changed ETag storage to be time_t, rather than int.
* Changed `If-None-Match` value parsing to use proper
time_t parsing, rather than `atoi`.
We emit FETCH_NOTMODIFIED if the resource hasn't changed.
Any errors from the fetch which are not already handled are
reported with an internal query page instead of a modal
dialog.
This is much less invasive for the user and much more in
keeping with how this is handled by other browsers.
The handler is similar to the timeout handler but the
functionality is kept separate as it is intended timeout
handling be extended in future.
cURL will prevent channel reuse if NTLM auth is enabled because
NTLM authenticates a channel not a request. As such we were
unable to reuse curl handles since we handed off connection
reuse to curl instead of our own handle cache. This mitigates
the effect, though curl authors are looking at fixing it upstream
too.

The curl fetcher can operate without openssl library being
available, additionaly curl itself may be compiled with a
different TLS library.
In either case this will simply cause the "unknown" error to be
reported for all TLS failiures and page information to lack any
certificate information.
Since OpenSSL 1.0.2 there has been hostname verification support
which cURL doesn't turn on for some reason. Turn it on so that
we get better hostname verification handling.
