* common/http.c (http_open): Add arg httphost.

SERVER.  Use https with a proxy if requested.

message.

ea0f5481f0 http: Add reference counting to the session object. 
* common/http.c (http_session_t): Add field "refcount".
(_my_socket_new, _my_socket_ref, _my_socket_unref): Add debug code.
(send_request, my_npth_read, my_npth_write): Use SOCK object for the
transport ptr.
(http_session_release): Factor all code out to ...
(session_unref): here.  Deref SOCK.
(http_session_new): Init refcount and transport ptr.
(http_session_ref): New.  Ref and unref all assignments.
--

Having the reference counted session objects makes it easier for the
application to pass around only an estream.  Without that the
application would need to implement an es_onclose machinery for the
session object.

37df3d5f59 Change license for some files in common to LGPLv3+/GPLv2+. 
Having the LGPL on the common GnuPG code helps to share code
between GnuPG and related projects (like GPGME and Libassuan).  This
is good for interoperability and to reduces bugs.

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 ;-)

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.

a7205a080c * http.h, http.c (send_request): Pass in srvtag and make its presence 
sufficient to turn the feature on.  (http_open): From here.
(http_document): And here.

hostname to a real hostname.  (main): Call it from here for the
HAVE_LIBCURL case (without libcurl is handled via the curl-shim).

* curl-shim.h, curl-shim.c (curl_easy_setopt, curl_easy_perform): Add
a CURLOPT_SRVTAG_GPG_HACK (passed through the the http engine).
