* dirmngr/ks-engine-hkp.c (map_host): Fix setting of r_poolname.

map_host is intended to return the name of the pool as an additional

only retrained if the pool name was retrieved from a DNS CNAME.

Ship the certificate for the sks-keyservers hkps pool. If the user
has specified that they want to use
hkps://hkps.pool.sks-keyservers.net, and they have not specified any
hkp-cacert explicitly, then initialize the trust path with this
specific trust anchor.

--
This feature is independent of --use-tor and automagically uses Tor if
available. The dirmngr.conf file needs to specify two keyservers to
make this work. For new installations this is done using the skeleton
file. This feature requires the Libassuan 2.4.2 to work.
This patch also fixes a memory leak of opt.keyserver en passant.

* dirmngr/ks-engine-hkp.c (map_host): Update the original 'hosttable'
entry instead of creating another one.
--
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.

At least the getaddrinfo implementation in glibc 2.19-13 from Debian
returns EAI_NONAME if the CNAME points to a too long list of A/AAAA
addresses. Looking at the wire the data is correctly returned from
the server but getaddrinfo seems to get confused by truncation and
retry. To fix this we resolve the CNAME again and call getaddrinfo
again with the canonical name.
