08311c51be winks: Fix RGB frame flipping and postprocessing
Uncompressed RGB frames can be (usually are) bottom-up
layout in DirectShow, and the code to flip them wasn't
properly ported from 0.10. Fix it.

Fix post-processing of RGB buffers. We need a writable
buffer, but the requests pool is holding an extra ref.
This could use more fixing to use a buffer pool

a31855d618 GstDeviceProvider implementation for WIN Kernel Streaming plugin
gst_ks_device_provider_probe() is a no-braier, just runs ks_enumerate_devices()
and reports the results.

Monitoring is a bit more tricky. We have to create a dummy message-processing
window and register device change notifications for it.

As kernel streaming can (and should) be used for audio capture and audio
playback, this change also has certain placeholders for such.

91853015b7 winks: Reset DTS to GST_CLOCK_TIME_NONE
Otherwise we might get a previous DTS set from a recycled buffer that we get
back from a buffer pool, which then confuses synchronization.

bd5e9a5442 ksvideosrc: Fix buffer handling
The pseudo buffer pool code was using gst_buffer_is_writable()
alone to try and figure-out if cached buffer could be reused.
It needs to check for memory writability too. Also check map
result and fix map flags.

32ba17cd0f Use gst_element_class_set_static_metadata()
where possible. Avoids some string copies. Also re-indent
some stuff. Also some indent fixes here and there.

d282a1d380 winks: improve error-handling
Most important part here is special-casing "device busy" so the application
is able to provide better feedback when another application is using the
device.

cddfa50d92 winks: performance improvements
* Make the driver write directly into each GstBuffer to avoid memcpy().
* Don't memset() the buffer before reusing it.
* Recycle memory by keeping two spare buffers. Two because the sink
  downstream may keep a ref to the previous buffer.

Note that we align buffers on highest possible byte boundary (4096) so we
don't have to take into account what kind of alignment the driver requires.

61dee51291 sys/winks/gstksclock.c (gst_ks_clock_worker_thread_func, gst_ks_clock_start):
Original commit message from CVS:
* sys/winks/gstksclock.c (gst_ks_clock_worker_thread_func,
gst_ks_clock_start):
Synchronize KS clock as a single-shot operation for now, there's not
much point in doing it periodically until we're actually using the
KS timestamps for anything else than just discarding old frames.
* sys/winks/gstksvideosrc.c (gst_ks_video_src_open_device):
Provide the GstClock when opening the device if we already have one.

Guard against capturing old frames by keeping track of the last
timestamp and also zero-fill the buffers before each capture.
Only assign a master clock if the pin hasn't already got one.
Actually free buffers on the way down to avoid a huge memory leak,
as this was previously done when changing state to ACQUIRE downwards
and we now skip that state on the way down.
Add some debug.

gst_ks_video_src_create):
Remove ENABLE_CLOCK_DEBUG define, it's GST_LEVEL_DEBUG after all.
Get rid of PROP_ENSLAVE_KSCLOCK and always slave the ks clock to the
GStreamer clock, it doesn't seem to hurt and matches DirectShow's
behavior. As an added bonus we usually get PresentationTime set for
each frame, so we can expand on this later for smarter latency
reporting (by looking at the diff between the timestamp from the
driver and the time according to the GStreamer clock).
Use an internal worker thread for opening the device, setting caps,
changing its state and closing it. This way we're a lot more
compatible with drivers that rely on hacks to do video-effects
between the low-level NT API and the application. Ick.
Start the ks clock and set the pin to KSSTATE_RUN on the first
create() so that we'll hopefully get hold of the GStreamer clock
from the very beginning. This way there's no chance that the
timestamps will make a sudden jump in the beginning of the stream
when we're running with a clock.
* sys/winks/kshelpers.c (CHECK_OPTIONS_FLAG,
ks_options_flags_to_string):
Reorder the flags to match the headerfile order, and make the string
a bit more compact.
* sys/winks/ksvideohelpers.c (ks_video_probe_filter_for_caps):
Avoid leaking KSPROPERTY_PIN_DATARANGES.
