This reverts commit 05e6de86461b4ab0c55880db0c83d7a7bd6c5bc1 which
broke audio decoding for PURE One Elite receivers, but fixed
slideshow and DLS decoding on PURE Sensia receivers.
Slides and DLS are now not working on PURE Sensia, but at least
audio is working again.

It's the patch from commit
e969ea8 AAC960 works now. All modes: LC/SBR/PS. Only for DAB+, not DRM.
without the copyright headers that create a ton of merge conficts

This allows callers to conditionally use new API features without
breaking compatibility with the earlier versions of the library.

This reverts commit 226601a8d9bce81455e161a0e26051d2f22c5d7a.
This change doesn't seem to be necessary any longer, a proper
fix seems to be included upstream now in
60a27b7fe5bf2c3b07ae7f679ca67c0c5cba3b00.

AAC Encoder: Saturate quantizer shift value to prevent
undefined behaviour.
In very rare cases the shift value 'totalShift = (16-4)-(3*(totalShift>>2))'
can be greater than accu data width. If you apply a shift with more then
31 bit the result depends on the architecture and is not defined in C.
For certain platforms zeros are shifted in. That would be our desired behaviour.
On other platforms the shift will be applied as modulo. For example >>34
would be applied as >>2. To prevent this discrepancy the shift value
is limited/saturated to DFRACT_BITS-1. 'accu >>= fixMin(totalShift,DFRACT_BITS-1)'.

This makes sure we read the right array element, corresponding
to all other array accesses in the same function, and all other
use of the isBook array elsewhere in the library.
This makes the fix in the previous commit ("Avoid too big changes
in isScale") work as intended, fixing other samples that triggered
assertions.

These values are delta encoded, but only steps [-60,60] are
possible to encode. If the difference between two values are
bigger than that, we end up with a sequence we are unable to
encode.
This fixes crashes on certain stereo samples at higher
bitrates.

Shifting by more than (or equal to) the variable length is
undefined in C.
This caused the quantized spectrum values to remain unshifted,
causing loud beeps in some samples.
The exact same change was originally applied in
657456949 (for AOSP) and in 24021f190 (in the separate fdk-aac
repo), but was overwritten and silently reverted by the new
upstream code drop for Android 4.2 in 381d69840a. After the code
drop, I chose not to reapply this change since the crashes that
it fixed had been fixed in other ways upstream and I was unable to
reproduce them after the new code drop.

This reverts commit 839ae290c1f5a263613bea1a5fde863e757a8849.
This change is no longer necessary on top of the new upstream,
I cannot reproduce the crash that this fixed with the new upstream.
