Update the rpctlscd in several areas.

This patch updates/fixes the rpctlscd in the following areas:

• Fix handling of the CRL file and add code to reload it when a SIGHUP is posted to the daemon.
• Move the creation of the SSL_CTX * to before the program daemonizes. This was done so that it can prompt for a passphrase for the case where the client has a certificate with an encrypted key.
• Fix up options.
• Make the handling of the server hostname in the certificate not accept a wildcard, as recommended by RFC6125.
