Drdynvc needs love (#8059)

* winpr: add lock operation on HashTables

* drdynvc: change the listeners array for a hashtable and other micro cleanups

* logonInfo: drop warning that is shown at every connection

Let's avoid this log, we can't do anything if at Microsoft they don't respect
their own specs.

* rdpei: fix terminate of rdpei

* drdynvc: implement the channel list with a hashtable by channelId
