Title: rdp_client_establish_keys() simplifications.

- Rename rdp_establish_keys() to rdp_client_establish_keys() as it is only
responsible for establishing keys on the client side.
- Simplify rdp_client_establish_keys() by using rdp_write_header() and
rdp_write_security_header() function instead of reimplementing them
and by using existing defines instead of magic values.
