384642f95f core: Fix sending incorrect GUID in RDSTLS auth request
The spec states that the GUID must be sent as a Base64-encoded GUID in
Unicode format. However in the redirection code we read the (correctly
formatted) GUID and convert it to a binary BLOB.

This PR removes the unnecessary conversion which now results in a
correct RDSTLS auth request.

It also removes some dead code in `rdstls_write_data`.

5bcc5326d0 [core,rdstls] fix rdstls_parse_pdu
When this function returns <= 0 the caller was considering it a pduLength
creating a bug.

Also fixed length calculation on some rdstls pdu types.

7c24da917e Add RDSTLS security protocol
The client tries to connect using RDSTLS only when it has received a
server redirection PDU with LB_PASSWORD_IS_ENCRYPTED flag.

The server exposes RDSTLS on negotiation if it has been configured on settings.
Then authenticates a client using configured credentials from settings:
RedirectionGuid, Username, Domain, Password.
