Appends Z to timestamp to force ISO8601 datetime parsing as UTC.
Without Z, some browsers (Chrome) interpret the timestamp as
localtime and others (Firefox) interpret it as UTC.

Newer versions of OS X use the blocks extension in VDA-related headers.
Some compilers, like current gcc, do not support the blocks extension
and fail to compile code using those headers.
If we only have a target compiler but no host compiler, the $type
variable will be empty once.
(Currently we fail to do a cross build if no host compiler is available
due to using the host compiler for processing option lists though.
But despite that, this comparison in configure needs quotes.)

The current condition can trigger in cases where it shouldn't, with
unexpected results.
Make sure that:
- container cropping is really based on the original dimensions from the
caller
- those dimenions are discarded on size change
The code is still quite hacky and eventually should be deprecated and
removed, with the decision about which cropping is used delegated to the
caller.
Introducing enforced sync points in arbitrary places is bad for
performance. Since the vast majority of receiving code (QSV VPP or
encoders, retrieving frames through hwcontext) will do the syncing, this
change should not be visible to most callers. But bumping micro just in
case.
This is also consistent with what VAAPI hwaccel does.
We can pick the correct slice index directly from the ID3D11VideoDecoderOutputView
casted from data[3].

No need to loop through the known surfaces, we'll use the requested surface
anyway.
The loop is only done for DXVA2.

Before this change, it was possible to overflow pic_order_cnt_lsb and
generate a stream with invalid POC numbering. This makes sure that
the field is large enough that a single IDR B* P sequence uses fewer
than half the available POC lsb values.
This change makes the configured GOP size be respected exactly -
previously the value could be exceeded slightly due to flaws in the
frame type selection logic.
