The old algorithm limited the length of a bucket chain by purging the
last 50% or the entries. Thus the first domains entered into the
cache were never purged. The new algorithm is a bit better: It also
limits the chain length on overflow to 50% but tries to keep the
entries indicating that a WKD is available in the cache. If there is
still space to keep more, those which clearly do not support WKD are
also kept.

We append the raw non-canonicalized local address part to the hash.
Servers who serve the requests from static files will ignore the
parameters and a test with posteo shows that also services using a
database ignore the parameter. The general idea is that service
providers may use their own canonicalization rules. The problem is
that we currently filter the returned key for the full mail address
and thus we will never see a key if the service did a different
canonicalization than we. So consider this to be an experiment.

There is no good reason to bind local port aggressively. It might be
some reason to do so, then, a user can specify it in /etc/resolv.conf
by the second argument of "interface" directive.
At least, it causes a problem on Windows. Binding a specified port in
user space can trigger the Firewall dialog on Windows. Since it can
be considered valid question, it is better not to bind with an
ephemeral port which is selected in user space, by default.

The old code simply did not use https for downloading of CRLS.
Instead it rewrote https to http under the assumption that the CRL
service was also available without encryption. Note that a CRL is
self-standing and thus it does not need to have extra authenticity as
provided by TLS. These days we should not use any unencrypted content
and thus this patch.
Be aware that cacert.org give a https CRL DP but that currently
redirects to to http! This is a downgrade attack which we detect and
don't allow. The outcome is that it is right now not possible to use
CAcert certificates.

This fixes a potential overflow if LFs are passed to the status

because neither the truncating in libassuan or our escaping is not the
Right Thing. In any case the functions need to be more robust and
comply to the promised interface. Thus the code has been factored out
to a helper function and N has been bumped up correctly and checked in
all cases.
For some uses this changes the behaviour in the error case (i.e. CR or
LF passed): It will now always be C-escaped and not passed to
libassuan which would truncate the line at the first LF.

This finalizes the feature to efficiently cache WKD checks. If a
standard WKD query returns no data, we queue a test to be run after
the end of the session (so that we do not delay the calling client).
This check tests whether the server responsible for the queried
address has WKD at all enabled. The test is done by checking whether
the "policy" file exists. We do not check the "submission-address"
file because that is not necessary for the web key operation. The
policy file is now required.

If a key has a http or https URL as preferred keyserver, fetch the key
from there. Previously, dirmngr unconditionally interpreted these
URLs as hkp servers.

* dirmngr/ks-engine-hkp.c (enum ks_protocol): New type.
(struct hostinfo_s): New flags indicating whether we already did a
A lookup, or a SRV lookup per protocol. Turn 'port' into an array.
(create_new_hostinfo): Initialize new fields.
(add_host): Update the port for the given protocol.
(map_host): Simplify hosttable lookup misses. Check the SRV records
for both protocols on demand, do the A lookup just once. Return the
correct port.
--
Previously, if a host had both a SRV record for hkp and hkps, the
wrong port was used for the protocol that was used second, because the
hostinfo did not store a port per protocol, and the hosttable does not
discriminate between hosts using the protocol.
Fix this by querying the SRV records on demand, storing a port per
protocol, and returning the right port.

* dirmngr/ks-engine-hkp.c (struct hostinfo_s): Add explicit length and
size fields.
(MAX_POOL_SIZE): New macro.
(create_new_hostinfo): Initialize new fields.
(host_in_pool_p): Adapt.
(select_random_host): Likewise.
(add_host): Likewise. Move the resizing logic here.
(hostinfo_sort_pool): New function.
(map_host): Simplify. Move the resizing logic away from here.
(ks_hkp_mark_host): Adapt.
(ks_hkp_print_hosttable): Likewise.
--
The current code assumes that the pool array is only filled when the
hostinfo object is created. This patch removes that limitation.

* dirmngr/dns.c (dns_so_check): Reinitialize sockets on address family
mismatch.
(enum dns_res_state): New states for querying over IPv6.
(dns_res_exec): Implement the new states by copying and modifying the
IPv4 variants. Branch to their respective counterparts if the current
list of resolvers using the current address family is exhausted.
--
This allows dirmngr to resolve names on systems where the nameservers
are only reachable via IPv6.

(DEFAULT_CONNECT_TIMEOUT): New.
(DEFAULT_CONNECT_QUICK_TIMEOUT): New.
(parse_rereadable_options): Handle new options.
(post_option_parsing): New. Use instead of direct calls to
set_debug() and set_tor_mode ().

(dirmngr_init_default_ctrl): Set standard connect timeout.
* dirmngr/dirmngr.h (opt): New fields connect_timeout and
connect_quick_timeout.

* dirmngr/server.c (cmd_wkd_get, cmd_ks_search, cmd_ks_get)
(cmd_ks_fetch): Implement --quick option.
--
The standard connect timeouts are way to long so we add a timeout to
the connect calls. Also implement the --quick option which is already
used by gpg for non-important requests (e.g. looking up a key for
verification).

* dirmngr/http.c: Include fcntl.h.
(http_session_s): Add field 'connect_timeout'.

(my_wsagetlasterror) [W32]: New.
(connect_with_timeout): New function.
(connect_server): Add arg 'timeout' and call connect_with_timeout.
(send_request): Add arg 'timeout' and pass it to connect_server.
(http_raw_connect): Add arg 'timeout'.
(http_open): Pass TIMEOUT from the session to connect_server.
--
Note that the non-blocking connect we implement is traditional a
pretty non-portable thing due to slighly different semantics. The
code uses the strategy W. Richard Stevens suggested in 1998.
Hopefully current OS versions got it all right.
The code has not been tested on Windows.

Using a single buffer pos for reading and writing caused the read
to return 0 as it read from the end of the buffer. Now we use
a seperate reader position.
