The same members between QSVVPPContext and VPPContext are removed from
VPPContext, and async_depth is moved from QSVVPPParam to QSVVPPContext
so that all QSV filters using QSVVPPContext may support async depth.
In addition, we may use QSVVPPContext as base context in other QSV
filters in the future so that we may re-use functions defined in
qsvvpp.c for other QSV filters.
This commit shouldn't change the functionality of vpp_qsv / overlay_qsv.

This is in preparation for reusing the code for other QSV filters. E.g.
deinterlacing_qsv may have an option array without format option

QSV filters may set this flag in preinit callback to turn on / off pass
through mode
This is in preparation for reusing the code for other QSV filters. E.g.
scale_qsv filter doesn't support pass through mode.

Set the expected default value for options in this callback, hence we
have the right values even if these options are not included in the
option arrray.

0 = original width/height
-1 = keep original aspect

This ensures all defined types are supported, even if only to report
their presence and print their size if a custom implementation is
not added.

The current code will apply them if the options string does not contain
a 'flags' substring, and will do so by appending the graph-level option
string to the filter option string (with the standard ':' separator).
This is flawed in at least the following ways:
- naive substring matching without actually parsing the options string
may lead to false positives (e.g. flags are specified by shorthand)
and false negatives (e.g. the 'flags' substring is not actually the
option name)
- graph-level sws options are not limited to flags, but may set
arbitrary sws options
This commit simply applies the graph-level options with
av_set_options_string() and lets them be overridden as desired by the
user-specified filter options (if any). This is also shorter and avoids
extra string handling.
This function currently treats AVFilterContext options and
filter-private options differently: the former are immediately applied,
while the latter are stored in a dictionary to be applied later.
There is no good reason for having two branches - storing all options in
the dictionary is simpler and achieves the same effect (since it is
later applied with av_opt_set_dict()).
This will also be useful in future commits.
Current code first sets AVFilterContext-level options, then aplies the
leftover on the filter's private data. This is unnecessary, applying the
options to AVFilterContext with the AV_OPT_SEARCH_CHILDREN flag
accomplishes the same effect.
It appears faster than the iterative method on my machine (1.06x
faster), so I'm guessing compilers improved over time (the iterative
version was slightly faster in the past).
Currently, in case of equality on the first color channel, the order of
the ref colors is defined by the hashing function. This commit makes the
sorting deterministic and improve the hierarchical ordering.
