    fftools/textformat/avtextformat: Make close functions return void

Just like normal close functions.

  • fftools/textformat/avtextformat : Initialize stuff earlier

    fftools/textformat/avtextformat: Initialize stuff earlier

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.

    fftools/textformat/avtextformat: Fix segfault upon allocation error

Would happen if an AVTextFormatContext's private context
could not be allocated.
