Our in-house parfait 1.1 code analysis tool complained that every exit
path from xf86ValidateModes() in hw/xfree86/common/xf86Mode.c leaks the
storeClockRanges allocation made at line 1501 with XNFalloc.
Investigating, it seems that this code to copy the clock range list to
the clockRanges list in the screen pointer is just plain insane, and
according to git, has been since we first imported it from XFree86.
We start at line 1495 by walking the linked list from scrp->clockRanges
until we find the end. But that was just a diversion, since we've found
the end and immediately forgotten it, and thus at 1499 we know that
storeClockRanges is NULL, but that's not a problem since we're going to
immediately overwrite that value as the first thing in the loop.
So we move on through this loop at 1499, which takes us through the
linked list from the clockRanges variable, and for every entry in
that list allocates a new structure and copies cp to it. If we've
not filled in the screen's clockRanges pointer yet, we set it to
the first storeClockRanges we copied from cp. Otherwise, as best
I can tell, we just drop it into memory and let it leak away, as
parfait warned.
And then we hit the loop action, which if we haven't hit the end of
the cp list, advances cp to the next item in the list, and then just
for the fun of it, also sets storeClockRanges to the ->next pointer it
has just copied from cp as well, even though it's going to overwrite
it as the very first instruction in the loop body.

DGA only handles master devices but it does intercept slave device events as
well (since the event handlers are per event type, not per device).
The DGA code must thus call into UpdateDeviceState to reset the button/key
state on the slave device before it discards the remainder of the event.
Test case:
- Passive GrabModeSync on VCP
- Press button
- Enable DGA after ButtonPress
- AllowEvents(SyncPointer)
- Release button
The button release is handled by DGAProcessPointerEvent but the device state
is never updated, so the slave ends up with the button permanently down.
And since the master's button state is the union of the slave states, the
master has the button permanently down.

This is a really awkward interface, since we're calling it well before
the driver knows what device it's going to drive. Drivers with both KMS
and UMS support therefore don't know whether to say they need I/O port
access or not, and have to assume they do.
With this change we now call it only to query whether port access might
be needed; we don't use that to determine whether to call a driver's
probe function or not, instead we call them unconditionally. If the
driver doesn't check whether port access was enabled, they might crash
ungracefully. To accomodate this, we move xorgHWAccess to be explicitly
intentionally exported (sigh xf86Priv.h) so that drivers can check that
before they attempt port access.
