Some more cleanups for vblank code on Intel.
...
The Intel 2d driver calls modeset before reinstalling the handler on
a vt switch. This means that vblank status ends up getting cleared
after it has been setup. Restore saved values for the pipestat registers
rather than just wiping them out.

Use the vbl_lock when maniputlating the refcount. Eventually I want to

Rework the management of vblank interrupts a bit.
...
When a vt switch occurs the irq handler is uninstalled. Interrupts
and the state tracking of what was enabled/disabled wasn't working
properly. This should resolve the reports of "slow windows" after a
vt switch, among other things. The radeon 2d driver seems to work a
bit more correctly than the Intel driver. With the Intel driver,
vblank interrupts will be enabled at system startup and will only
be disabled after an additional modeset (vt switch, dpms, randr event).
With this patch, I am able to run glxgears synced to vblank and
vt switch while it is running without ill effects.
