msi: Store the number of types we queried. We were leaking these types because we didn't have the correct count.

This change also fixes weird 8-space indenting in free_merge_tables.

msi: Make sure we don't access pcchValueBuf when szBuffer is NULL, as pcchValueBuf is not required to be initialized in this case.

rpcrt4: Override inquire_auth_client for ncalrpc transport to always indicate that the connection is authenticated.

The protocol is local only and therefore encryption/decryption isn't
necessary to keep the data private, and methods are built into the
protocol for impersonating the user of the calling thread.

rpcrt4: Process control packets in the server synchronously to avoid races when using 3-factor authentication.

The client has nothing to wait for after sending the AUTH3 packet
before sending the first request packet. Therefore, we must ensure
that the AUTH3 packet has finished being processed before we start
processing any request packets.
