The new options for the keyserver command are useful for debugging.
For example:

  $ tools/gpg-connect-agent -S /usr/local/var/run/gnupg/S.dirmngr \
          'keyserver hkp://keys.gnupg.net' \
          'keyserver http://http-keys.gnupg.net' \
          'keyserver --resolve --hosttable' /bye

yields:

Werner Koch 231d27e0fe Make HKP keyserver engine work again.
We had some debug code here which prevented it from working.
The host selection code still needs a review!

	* ks-engine-http.c (ks_http_help): Do not print help for hkp.
	* ks-engine-hkp.c (ks_hkp_help): Print help only for hkp.
	(send_request): Remove test code.
	(map_host): Use xtrymalloc.

	* certcache.c (classify_pattern): Remove unused variable and make
	explicit substring search work.

Werner Koch f1e9f510ec Add code for explicit selection of pooled A records.
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.

Werner Koch f02d972aec Support key fetching using HTTP.
A simple test case is:

  gpg2 --fetch-key http://werner.eifelkommune.de/mykey.asc

Werner Koch 2c79a2832c Add finger support to dirmngr.
The basic network code from http.c is used for finger.  This keeps the
network related code at one place and we are able to use the somewhat
matured code form http.c.  Unfortunately I had to enhance the http
code for more robustness and probably introduced new bugs.

Test this code using

  gpg --fetch-key finger:wk@g10code.com

(I might be the last user of finger ;-)

Werner Koch b008274afd Nuked almost all trailing white space.
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.
