The AAC_PCM_OUTPUT_CHANNELS option no longer exists under the
same name nor enum value any longer, and the AUDIO_CHANNEL_TYPE
enum has been changed in a way which may break users.
This is a bug fix patch from Fraunhofer, amending/replacing/extending
the previous commit which only extended the table to 55 elements.
(In my previous fix, 55 seemed to be enough for the issue at hand at
least. A few of the coefficients had slightly different rounding than
what Fraunhofer had used though).
This will show up in AOSP in the next code drop as well.
For sample rates >= 64 kHz with short blocks, the largest sfb
width is 36, which after grouping can be multiplied with 3,
ending up as 108. GetInvInt needs to be able to support
the largest grouped sfb width, divided by two (3 * 36 / 2 = 54).
This fixes VBR encoding with sample rates >= 64 kHz.
fseek(SEEK_CUR) doesn't work for nonseekable streams (such
as pipes).
Only do this for skipping past small chunks; don't use it for
skipping past the actual data for non-streamed input.
Fix AIX build failure with IBM xlC compiler due to conflicting
definition of M_PI. The libSYS/include/genericStds.h definition is
guarded with #ifndef M_PI, but was included before <math.h> which
defines M_PI with more significant digits.
Revise decoder output delay determination. The output delay consisted of
concealment and limiter delay. SBR delay was not covered but must be
considered for gapless playback delay compensation.

Improve flushing and seeking.
Add field to the API stream info structure signaling the additional output
delay for flushing and delay compensation.

Introduce time domain limiter. The module is per default enabled for all
AAC-LC and HE-AAC v1/2 streams. For all ER-AAC-LD and ER-AAC-ELD streams
the limiter is disabled per default. The feature can be en- or disabled
via dynamic API parameter. Note that the limiter introduces an additional
output delay which depends on the module parameters and the streams
sampling rate.

The libSYS/include/machine_type.h header file states LONG should be
"Data type representing 4 byte signed integer on all supported
platforms" but only provided for defining LONG as INT and ULONG as
UINT when __x86_64__ was defined. This has been changed to when
__LP64__ is defined, so that it also applies to AArch64. The change
to libFDK/include/common_fix.h is then needed to get the project to
compile.

The enum only contains the constant values 0, 1 and 2. This produces
the warning "comparison of constant 6 with expression of type
'PS_RESOLUTION' is always false" in clang for the first check
in the getNoBands function (but apparently not for the second one
even though mode>=3 shouldn't ever happen for a valid PS_RESOLUTION
value either). This could allow the compiler to completely remove
the conditions that shouldn't be able to occur even though they
actually are used and are necessary.
By passing the value as UINT instead, it is clear to the compiler
that all the checks are necessary.
