Prevents that the client crashes if the peer does not specify
the 'realm' and/or 'nonce' values. These pointers are
dereferenced in DigestCalcHA1() and DigestCalcResponse();
hence, if not set, a null-pointer dereference would occur.

The problem is located in the file proxy.c within
"establish_http_proxy_passthru": To keep buffers small long
base64-encoded NTLM-Strings are truncated.
But the truncating is done on a wrong place: base 64 strings can be
cut every 4 chars. the buffer is 128 bytes - including the terminating
\0, so the usable data is only 127 bytes. And decoding a 127 char
base64 string fails... this is why the ntlm authentication fails in
certain cases (long strings)...

easier for OpenVPN client UIs to start a pre-existing client config file with
proxy options, or to adaptively fall back to a proxy connection if a direct
connection fails.

the auth method required by the proxy.
Added http-auth "auto-nct" flag to reject weak proxy auth methods.
Added HTTP proxy digest authentication method.
Removed extraneous openvpn_sleep calls from proxy.c.

as well as a failure of the code to check the return value from
base64_decode.
Fixed compiler warnings in the new NTLM phase 3 code about implicit
casting between signed and unsigned char *.
