We do not support using filters without AVFilterGraph in practice
anyway, so there is no point in pretending we do.

This is more consistent with the naming in the rest of Libav.

This is required for letting applications to create and destroy
AVFilterInOut structs in a convenient way.

Unlike avfilter_graph_parse(), it returns unlinked inputs and outputs
to the caller, which allows parsing of graphs where inputs/outputs are
not known in advance.

It will be used for logging, possibly also AVOptions.

Require "void *" rather than "AVClass *" for the log context type.

Add missing multiple inclusion guards; clean up #endif comments;
add missing library prefixes; keep guard names consistent.

Make avfilter_graph_free() free not only the internal structures, but
also the allocated graph, and set the graph pointer to NULL for
increased safety.

Simplify usage.

and move their declaration to internal.h. These functions are never
used in application code, so it is better to consider them internal
functions, this can be changed later if necessary. Simplify API.

Simplify, and less confusing for the user.

Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.'  to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".
