This adds Csock::ConvertAddress() which produces printable addresses. We use
this function in CZNCSock to strip away 4in6 prefixes (e.g. ::ffff:127.0.0.1).

WebModules use CHTTPSock for the HTTP server. That class requires a CModule
instance for working since it's based on CSocket. This was solved by creating a
fake module instance which is destroyed when the socket is destroyed.
The problem here was that CSocket's destructor tried to access that module
instance which was already destroyed resulting in a use-after-free.

This one is partly due to cppcheck, too, because it warned that one of CModule's
constructors didn't initialize m_bGlobal.

This removes all of znc's c-ares code and instead enables Csocket's built-in
version. That code is newer than ZNC's, but should hopefully work just as good.
Let's wait for the bug reports....

CSocket sometimes calls our select() wrapper with writeds == NULL and we didn't
handle this case at all which lead to a NULL pointer dereference.

Everything which isn't a CClient with a successful login counts as an
unidentified connection in this context. Modules who don't want this kind of
limit on their listening sockets can override CSocket::ConnectionFrom(), but
their sockets will still count towards this limit.

Every socket which is based on CZNCSock will now use c-ares for its name
resolving. This is possible thanks to CSocket's Csock::GetAddrInfo() which
lets one override the DNS lookup.
This can be disabled with --disable-c-ares.
If IPv6 is enabled and Csocket didn't specify which kind of lookup (ipv4/ipv6)
it wants, we first do an ipv4 lookup. If that lookup doesn't yield any useful
result, we try again with an ipv6 lookup. If one wants to force ipv6 usage on a
domain which also resolves to an ipv4 address, he has to set an ipv6 vhost.
