* curl-shim.h, curl-shim.c (curl_free): Make into a macro.
(curl_version_info): New. Only advertises "http" for our shim, of
course.
curl_writer_finalize): New functionality to handle binary format keys by
armoring them for input to GPG.
* gpgkeys_curl.c (get_key), gpgkeys_hkp.c (get_key): Call it here.
protocols we handle. Directly pass them to curl or fake-curl and see if
an error comes back.
* curl-shim.h, curl-shim.c (handle_error), ksutil.c (curl_err_to_gpg_err):
Add support for CURLE_UNSUPPORTED_PROTOCOL in fake curl.
* Makefile.am: Don't need -DFAKE_CURL any longer since it's in config.h.

* gpgkeys_http.c: Don't need to define HTTP_PROXY_ENV here since it's
in ksutil.h.
* gpgkeys_curl.c (get_key, main), gpgkeys_hkp.c (main): Pass AUTH
values to curl or curl-shim.
* curl-shim.c (curl_easy_perform), gpgkeys_curl.c (main),
gpgkeys_hkp.c (main): Use curl-style proxy semantics.

* ksutil.h, ksutil.c (curl_err_to_gpg_err, curl_writer): Copy from
gpgkeys_curl.c.
* gpgkeys_oldhkp.c: Copy from gpgkeys_hkp.c.

* gpgkeys_curl.c (writer): Discard everything outside the BEGIN and
END lines when retrieving keys. Canonicalize line endings. (main):
Accept FTPS.

* gpgkeys_curl.c (main): Add "debug" option to match the LDAP helper.
Add "check-cert" option to disable SSL certificate checking (which is
on by default).

(there is natural support in libcurl for the http_proxy environment
variable).
* Makefile.am: Remove the conditional since this is all handled in
autoconf now.

gpgkeys_http.c (main), gpgkeys_ldap.c (main): Make sure that a "timeout"
option passed with no arguments is properly handled.
