e4a308a545 fix caps to avoid videoconvert bug in 1.8 which corrupts data 
Previous way of creating caps left invalid colorimetry field 0:0:0:0,
which combined with a bug present in GStreamer 1.8 led to GRAY16_LE data
being corrupted when converted to GRAY16_BE (or vice versa). Current
method will properly initialize colorimetry field, avoiding this problem
in 1.8.

61288388c5 niimaqsrc: improve timestamping 
_create often locks the mutex before the start_frame_callback, resulting
in bad timestamps. Also an estimated duration causes d3dvideosink to give
poor display, so comment this out for now.

1033aea633 niimaqsrc: another attempt at robust date-timestamping

a9cfe6062d niimaqsrc: use simpler method of correlating buffers with timestamps 
Drop the mutexes and special struct, just create ring buffer of
GstClockTimes. Also rely on callbacks for start/stop of acquisition.

The absolute date-timestamps need to be corrected for the first buffer
timestamp.

d6fe385cb9 niimaqsrc: add avoid copy mode 
Unfortunately IMAQ only lets you examine one buffer at a time, and elements
like queue store up multiple buffers, so avoid-copy=TRUE can only be used in
pipelines without queues or other such elements.

Also, make property strings static.

9002eb1f70 niimaq: handle byte alignment during copying 
Previously if the row stride wasn't a multiple of 4, display would not work
correctly. Rely on NI-IMAQ to fix the byte alignment for us. This hasn't
been thoroughly tested yet however.

7c251fa83a niimaq: use standard video caps 
Even though NI-IMAQ can specify 10-, 12-, or 14-bit images, no other standard
element supports it, and in 0.11/1.0 caps are simplified to be gray8/gray16.
We can always add back custom caps if there is a real need for it.

fa883c1ca1 niimaq: make sure timelist exists before modifying it 
Caused seg fault unless delay was introduced (e.g. with debugging messages
on). Still need to investigate why we don't get a timestamp before the
first frame.
