avfilter/formats: Remove unused functions

Browse Source 
This commit removes ff_parse_sample_format(), ff_parse_time_base() and
ff_query_formats_all_layouts() from libavfilter/formats.c. All of these
functions were completely unused. ff_parse_time_base() has not been used
at all since it had been added in 3448404a707b6e236a2ffa7b0453b3300de41b7b;
the last caller of ff_parse_sample_format has been removed in commit
d1c49bcae9. And the one and only caller of
ff_query_formats_all_layouts() (the asyncts filter) has been removed in
commit a8fe8d6b4a.
