dirmngr: Add per-session verify callback to http.c

* dirmngr/http.h (http_verify_cb_t): New type.
* dirmngr/http.c (http_session_s): Add fields flags, verify_cb, and
verify_cb_value.
(http_session_new): Remove arg tls_priority.  Add args verify_cb and
verify-cb_value.  Store them in the session object.
(send_request): Use per-session verify callback.
(http_verify_server_credentials) [HTTP_USE_NTBTLS]: Return
GPG_ERR_NOT_IMPLEMENTED.
* dirmngr/ks-engine-hkp.c (send_request): Adjust for changed
http_session_new.
* dirmngr/ks-engine-http.c (ks_http_fetch): Ditto.
* dirmngr/t-http.c (main): Ditto.

* dirmngr/server.c (do_get_cert_local): Replace xmalloc by malloc.
