Too many crashes observed. Can't be helped until the autocorrelation

With this, user applications which use custom IO and have set a IO context will not have
their already opened IO context ignored and glob/seq being interpreted
Comments and tests from maintainers of user apps are welcome!

Updates libkvazaar to pass the exact frame rate to Kvazaar by setting
the numerator and denominator separately instead of a single floating
point number. The exact frame rate is needed for writing timing info to
the bitstream.
Requires Kvazaar version 0.8.1.

This feature is mostly only used by NLE software, and is
both of dubious value being enabled by default, and a
possible security risk.

Currently scale filter accepts expressions in its width and height
parameters but evaluates them only once at init and replaces them with
their actual values. Later on, if any parameter of incoming frames
changes - ie those were used in the original size expressions - then
they new values will not have any affect for width and heigth values.
They remain the same. This patch makes possible that width and height
expressions be evaluated frame-by-frame basis if width/height/sar/format
properties of incoming frame would change. To retain the current
behaviour and not to break any earlier app, a new config parameter has
been introduced. Its name is "eval" and it has two distinct values:
"init" and "frame". The default value is "init".
This feature is very usefull in case of DVBT mpeg-ts streams where SAR
may change time-by-time from 4/3 to 16/9 and vica-versa and the size
remains the same and you want to create a variable sized output with 1/1
SAR.

vf_overlay video filter accepts expressions in its parameters. In
'frame-by-frame' evaluation mode it recalculates them regularly, but
incoming video frame size changes did not reflect in their values. So if
you used width or height of any source videos in expressions as
parameters, they stayed on their initial values. This patch corrects
this bug.

Now that the seek only happens with the right mouse button, it makes
sense to toggle full screen when double-clicking with the left mouse

Seeking by clicking on the video window can be annoying, because
the user might click on it accidentally while eg. trying to get
focus on it, and ffplay seeks instead.
This commit changes that behaviour to seek only when the right
mouse button is used to click and drag on the window.

Adding mastering display metadata struct to avutil. The mastering display metadata contains information
about the mastering display color volume (SMPTE 2086:2014).
This info comes from HEVC in the SEI_TYPE_MASTERING_DISPLAY_INFO and is soon to be included in MKV:
https://mailarchive.ietf.org/arch/search/?email_list=cellar&gbt=1&index=sZyfPTM-QY69P-0omfOIiTN622o
so it is similar to SEI FPA / stereo_mode in MKV and as such this patch follows how AVStereo3D is implemented.
I'll add support to HEVC in a follow-up (and MKV when spec is approved).

Match the use of AV_PIX_FMT_PAL8 for 1-bit QuickTime Animation in
lavc/qtrle. To reiterate, 1-bit video is not necessary black & white in
QuickTime, merely bi-level. The two colors can be any color. The palette,
either included in the sample description, or the default Macintosh
palette (black & white for 1-bit video) will be set in lavf/qtpalette.
See the QuickTime File Format Specification for details.
