  Port r17546 from Tremor; although pieces had made it over to libvorbis, a comprehensive
  port and verification was called for.  This patch provided some additional floor0
  hardening:
  
    floor0 code could potentially use a book where the number of vals it
    needed to decode was not an integer number of dims wide.  This caused
    it to overflow the output vector as the termination condition was in
    the outer loop of vorbis_book_decodev_set.
  
    None of the various vorbis_book_decodeXXXX calls internally guard
    against this case either, but in every other use the calling code does
    properly guard (and avoids putting more checks in the tight inner
    decode loop).
  
    For floor0, move the checks into the inner loop as there's little
    penalty for doing so.
  
  [an equivalent change was already in libvorbis, but I've
  harmonized the code with tremor]
  
    For floor0, move the checks into the inner loop as there's little
    penalty for doing so.  Add commentary indicating where guarding is
    done for each call variant.

  Add a clarification to the floor1 decode spec, since I had to re-determine some of what
  it says for myself after not thinking about it for 15-ish years.
  
  Also, fix an indentation bug that occurred due to TABs sneaking in
