Commit client-side enhancements contributed by DDvO.  This includes the ability to specify a pre-generated CSR when using estclient.
Commit the server-side changes contributed by DDvO.  This includes some bug fixes with how the verbose output is handled in estserver.  Added support to not require HTTP authentication when TLS client auth succeeds (enable using estserver -o option).  Unlike the original patch contributed by DDvO, the -n option is retained in case HTTP authentication should be completely disabled.
