Integer writing is impossible here as the first branch was dead code,
so remove it completely.

This would make the goto dead code and also would not properly
call avtext_context_close.

Setting print_graphs_format (in case no -print_graphs_format
option was specified) is racy, as is using av_strtok()
to split it. Both have been removed.
Notice that using av_strtok() was destructive: In the absence
of races the options would only have been applied for the
first initialization.

- add set_str() function to free before overwriting
- fix some other leaks

The key benefits are:
- Different to other graph printing methods, this is outputting:
- all graphs with runtime state
(including auto-inserted filters)
- each graph with its inputs and outputs
- all filters with their in- and output pads
- all connections between all input- and output pads
- for each connection:
- the runtime-negotiated format and media type
- the hw context
- if video hw context, both: hw pixfmt + sw pixfmt
- Output can either be printed to stdout or written to specified file
- Output is machine-readable
- Use the same output implementation as ffprobe, supporting multiple
formats

Also change writer_printf signature in AVTextWriter to use va_list,
so that it can be called by the new function writer_printf()
in tf_internal.h.

changes to the signature of avtext_context_open().

Instead of initializing a new BPrint in case of UTF decode error,
re-use the same BPrint struct and just clear it
for each iteration.

avtext_context_close() calls av_opt_free() on an AVTextFormatContext
as well as av_bprint_finalize() on the containing section_pbuf
AvBPrints, yet it can happen that the AVBPrints have not been
initialized (only zeroed) and that av_opt_set_defaults() has
not been called. This works, but it is not really documented to do so.
So ensure that the options and the AVBPrints have been initialized
when avtext_context_close() is called.

avtextwriter_create_file() creates an AVIOContext whose pointer
resides in its private context. If it were not always closed on
uninit, the AVIOContext would leak, so it makes no sense
to have this parameter.
