Missing features:
=================
-- MHD_get_daemon_info is not implemented
+- MHD_get_daemon_info is not implemented (always returns NULL)
+- SSL support does not work with SELECT-based threading modes
+ (issue is that the gnutls state machine does not like EAGAIN/EINTR
+ return values from send/recv, despite having tons of
+ branches on those values).
- SSL code is still too large:
* libgcrypt is used, and is also bloated
=> integrate required portions of libgcrypt into our tree
