* configure.ac: Check for inet_ntop.
* m4/libcurl.m4: Provide a #define for the version of the curl
library.
* keyserver/gpgkeys_hkp.c (main, srv_replace): Call getaddrinfo() on
each target. Once we find one that resolves to an address (whether
IPv4 or IPv6), pass it into libcurl via CURLOPT_RESOLVE using the
SRV name as the "host". Force the HTTP Host header to be the same.
* common/http.c (send_request, connect_server, http_open): Use a
struct srv instead of a single srvtag so we can pass the chosen host
and port back to the caller.
(connect_server): Use the proper port in the HAVE_GETADDRINFO case.
* keyserver/curl-shim.c (curl_easy_perform): Use struct srv and log
chosen host and port.
* keyserver/gpgkeys_hkp.c (main): Properly take the port given by SRV.
* scripts/gitlog-to-changelog: New script. Taken from gnulib.
* scripts/git-log-fix: New file.
* scripts/git-log-footer: New file.
* scripts/git-hooks/commit-msg: New script.
* autogen.sh: Install commit-msg hook for git.
* doc/HACKING: Describe the ChangeLog policy.
* ChangeLog: New file.
* Makefile.am (EXTRA_DIST): Add new files.
(gen-ChangeLog): New.
(dist-hook): Run gen-ChangeLog.
Rename all ChangeLog files to ChangeLog-2011.
sufficient to turn the feature on. (http_open): From here.
(http_document): And here.
* gpgkeys_hkp.c (srv_replace): New function to transform a SRV
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).
* curl-shim.h (curl_version): No need to provide a version for
curl-shim as it always matches the GnuPG version.
* gpgkeys_curl.c, gpgkeys_hkp.c (main): Show which version of curl
we're using as part of --version.
* gpgkeys_curl.c, gpgkeys_finger.c, gpgkeys_hkp.c, gpgkeys_ldap.c
(show_help): Document --version.
number options are passed as long.
* curl-shim.c (curl_easy_setopt): Minor tweak to match the real curl
better - libcurl uses 'long', not 'unsigned int'.
* gpgkeys_curl.c (main): Use curl_version_info to verify that the
protocol we're about to use is actually available.
* curl-shim.h, curl-shim.c (curl_free): Make into a macro.
(curl_version_info): New. Only advertises "http" for our shim, of
course.
