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).
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.
