Due to our switch to Libdns getsrv didn't worked correctly because it
returned -1 for an NXDOMAIN. However, it is perfectly okay to have no
SRV record and thus we change the way this function is called to be
aligned with the other functions and also map NXDOMAIN to a zero SRV
record count.

This option allows for runtime switching to the system's standard
resolver. This is mainly useful to work around possible bugs in the
optional resolver libraries (as of now ADNS). Note that on Windows
there is no code to use systems's resolver and thus for full
functionality dirmngr must be build with a separate resolver.
This patch also does way with configure options to disable the use of
CERT and SRV records.

--
Previously, if a keyserver was given using its IP address
(e.g. 'hkp://127.0.0.1'), 'map_host' would create two entries in the
'hosttable', one with the name '127.0.0.1', and the second one with
the name 'localhost' and 'v4addr' being set to '127.0.0.1'. But the
first entry is the one being used for lookups, and since the 'v4' flag
is not set, the 'HTTP_FLAG_IGNORE_IPv4' is used when doing the http
request, making it fail.

Only report support for the hkps scheme when GnuPG / dirmngr

This helps debuging and enable the user to detect whether support
for hkps is included by doing a

Currently hkps will be listed as a supported scheme but trying to
add a keyserver using it will silently fail.
As a digression, https is never listed as a valid scheme.

Also removed the warning that the widnows part has not yet been done.
AFAICS, the current mingw supports the all used socket functions.
The asymmetric quotes used by GNU in the past (`...') don't render
nicely on modern systems. We now use two \x27 characters ('...').
The proper solution would be to use the correct Unicode symmetric
quotes here. However this has the disadvantage that the system
requires Unicode support. We don't want that today. If Unicode is
available a generated po file can be used to output proper quotes. A
simple sed script like the one used for en@quote is sufficient to
change them.
The changes have been done by applying
sed -i "s/\`\([^'\`]*\)'/'\1'/g"
to most files and fixing obvious problems by hand. The msgid strings in
the po files were fixed with a similar command.
We had some debug code here which prevented it from working.

Since 2009-12-08 gpg was not able to find email addresses indicated
by a leading '<'. This happened when I merged the user id
classification code of gpgsm and gpg.
To better cope with round robin pooled A records like keys.gnupg.net
we need to keep some information on unresponsive hosts etc. What we
do now is to resolve the hostnames, remember them and select a random
one. If a host is dead it will be marked and a different one
selected. This is intended to solve the problem of long timeouts due
to unresponsive hosts.
The code is not yet finished but selection works.
We better do this once and for all instead of cluttering all future
commits with diffs of trailing white spaces. In the majority of cases
blank or single lines are affected and thus this change won't disturb
a git blame too much. For future commits the pre-commit scripts
checks that this won't happen again.
