When using AV_NOPTS_VALUE (which expands to INT64_C(0x8000000000000000))
as union initializer for a double field, the c99 converter needs to
interpret this constant when filling the union initializer, and it is
interpreted as a positive value.

When converting AV_NOPTS_VALUE to a double, MSVC 2010 ends up with
the same positive value as the c99 converter, while MSVC 2012 gets
a negative value.

This results in an infite loop in various FATE tests on MSVC 2012.

c99wrap choked on initialization of .dbl start_time option with
AV_NOPTS_VALUE: Unable to parse int64_t as expression primary

This allows for dropping or duplication to match a particular start time.

It should not be reinitialized if the link properties change.

Deprecate AVFilterBuffer/AVFilterBufferRef and everything related to it
and use AVFrame instead.

Any alleged performance benefits gained from the split are purely
mythological and do not justify added code complexity.

By default, fps selects frames near PTS 0, 0.5, 1.5, 2.5, etc.
With round=down, it selects the frames near PTS 0, 1, 2, 3, etc.

A number of compilers, for example those from TI and IBM, choke on
these initialisers.  The current style is also quite ugly.

This allows the iteration callbacks to discover the internal class and
options, and show them when required.

Signed-off-by: Martin Storsjö <martin@martin.st>

This reduces code duplication and prevents stale pointers from remaining
on the link.

It is not used in any filters currently and is inherently evil. If
passing binary data to filters is required in the future, it should be
done with some AVOptions-based system.

The macro can be used to define consistently the internal class of a
filter, save some typing and factorize.

While here:
    - add missing .version and .category,
    - make .class_name consistent across filters,
    - align declarations.

They are only useful inside filters and we don't allow user filters for
now.

avfilter_default_filter_name() is supposed to access an AVFilterContext
struct, if used with a private struct it will cause a crash since it will
access fields which are non defined in the private struct.

The function is modelled after av_default_item_name(), and will print the
name of the instance filter if defined, otherwise the name of the filter.

This allows to show the instance name in the log, which is useful when
debugging complex filter graphs.
