    Use wsi_rel_to_abs_time helper function to convert relative
    timeouts to absolute timeouts without causing overflow.

Suggested-by: Jason Ekstrand <jason.ekstrand@intel.com>
v6:
    Change WSI fence wait function to return VkResult instead of
    bool. This makes the meaning of the return value easier to
    understand, and allows for the indication of failure.

    Also change the WSI fence wait function to take only absolute
    timeouts and not provide an option for a relative timeout. No
    users wanted relative timeouts, and it's simpler if that option
    isn't available.

    Terminate the DPMS property loop once we've found the property.

    Assert that the fence hasn't already been destroyed in
    wsi_display_fence_destroy.

    Rearrange the event handler function order in the file to place
    routines in an easier to find order.

Suggested-by: Jason Ekstrand <jason.ekstrand@intel.com>
v7:
    Adapt to API changes for surface_get_capabilities

v8:
    Use wsi->alloc in register_display_event so that callers
    don't have to dig out an allocator for us.

v9:
    Fix a few minor formatting issues

Suggested-by: Jason Ekstrand <jason.ekstrand@intel.com>
v10:
    Use wsi->alloc if none provided in wsi_display_fence_alloc.

    Now that drivers are expected to pass the allocator argument
    straight through from the application, we need to check those
    for NULL everywhere.

anv: Support wait for heterogeneous list of fences [v3]

Handle the case where the set of fences to wait for is not all of the
same type by either waiting for them sequentially (waitAll), or
polling them until the timer has expired (!waitAll). We hope the
latter case is not common.

While the current code makes sure that it always has fences of only
one type, that will not be true when we add WSI fences. Split out this
refactoring to make merging that clearer.

v2: Adopt Jason Ekstrand's coding conventions

    Declare variables at first use, eliminate extra whitespace between
    types and names. Wrap lines to 80 columns.

v2:

    Make anv_wait_for_fences with !waitAll check all fences at least
    once, even if the requested timeout has already passed.
