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.

On Windows, GdipCreateBitmapFromHBITMAP creates a copy of the bitmap, not
a reference. Currently, we match this behavior, but this is only because
we cannot yet create bitmap objects that reference existing memory. If
GdipCreateBitmapFromScan0 were fixed to do this, FromHBITMAP would break.

Therefore, we always pass NULL to FromScan0 so that it allocates new memory
for the bitmap.

If we are passed SHGFI_PIDL, szFullPath is not initialized. If we're passed
the flags PIDL, USEFILEATTRIBUTES, and an icon flag, we will try to use the
uninitialized filename to get the icon. Since the test claims that the
function should return an icon in this case, and we cannot always convert
a pidl to a path, we should just use the pidl.

Opening a storage when it has already been opened now fails with
STG_E_ACCESSDENIED. If we attempt to copy a storage to its own child, this
will happen during the copy.

Spotted by valgrind.

+/- aren't affected by customdraw settings, only per control
set colors used.
