mdct comment change (correct the vorbis window function description)

Roll a libvorbis fix into tremor (if audio stream has only one page
and that page is a short page)

Latest improvements from Nicolas Pitre. Reviewed by Monty

From Nicolas's notes:

 - Includes my previous patch with interpolation code for correct accuracy
   with all block sizes.
 - Interlaces sin and cos values in the lookup table to reduce register
   pressure since only one pointer is required to walk the table instead of
   two.  This also accounts for better cache locality.
 - Split the lookup table into two tables since half of it (one value every
   two) is only used in separate section of the code and only with large
   block sizes.  Therefore the table size used for the common case is reduced
   by 2 accounting for yet better cache usage.
 - Abstracted all cross products throughout the code so they can be easily
   optimized.  First this prevents redundant register reloads on ARM due to
   the implicit memory access ordering, next this allowed for the
   opportunity to hook some inline assembly to perform the actual operation.
 - Fix layout of current assembly in asm_arm.h to match GCC's output (more
   enjoyable to read when inspecting the final assembly) plus some
   constraint correctness issues.
 - Added a memory barrier macro to force the compiler not to cache values
   into registers or on the stack in some cases.
 - Reordered some code for better ARM assembly generation by
   the compiler.

Nicolas Pitre's newer, more polished MDCT.  From his summary:


  - All redundant lookup tables eliminated;
  - mdct_init removed;
  - negative operands factorized out;
  - loop layout to allow the compiler to nicely use the ARM's
    dereference with preincrement and write back addressing mode for
    the T and V pointers;
  - miscelaneous code optimisations and uniformisation.
