- Fix for the spectral misalignment issue observed between HF and LF for 4:1 eSBR
- Delay synchronization between SBR encoder and the core coder
- Delay handling for the decoded files using pre-roll frames on encoder
- Bug fixes
Testing: Smoke-test

Significance:
--------------
- Fixes all the the warnings observed for libxaac decoder library when compiled with clang-16 (x86_64).
- Adjusts the conditional check to validate the 4:1 system's SBR range start frequency border.
Testing:
---------
- All previous fuzzer crashes are tested. No crash observed.
- CTS and Conformance for x86, x86_64, armv7 and armv8 are passing.
- The bit-writing logic had to be skipped when no bits were to be written. Updated the existing check for the same.
- This change also resolves an issue identified by oss-fuzz.

Significance:
--------------
- Possibility of accessing uninitialized access to structure members of a local scratch structure uncovered with fuzzer testing.
- The changes in this commit handle such cases.

Significance:
========
[x] Aligned buffer access for scratch memory and scratch memory optimization.
Testing:
=====
[x] MSVS Conformance and CTS are passing.
[x] All previous fuzzer crashes are tested. No crash observed.
[x] For platforms, Conformance tested with different combinations.
[x] Tested Conformance with gcc builds for x86, x86_64, armv7 and armv8.
[x] Tested Conformance with clang builds with address and memory sanitizer flags for x86_64 and armv8.
There hasn't been a non-neon platform build in years. Even the NDK hasn't supported non-neon for two years now.

These changes handle the Heap-buffer-overflow WRITE 8 runtime error reported
due to unsupported channel configuration for USAC.
Bug: ossFuzz:64960
Test: poc in bug
This change handles the error reported while processing
individual bitstream element in case of multi-channel streams.
Bug: ossFuzz: 64022
Test: poc in bug
These changes handle the index-out-of-bounds runtime error reported
when the value of arbitrary downmix residual bands is greater than or equal
to the number of parameter bands.
Bug: ossFuzz:63564
Test: poc in bug
These changes handle the divide-by-zero runtime error reported
while calculating the downmix coefficients because
base channel count was coming zero.
Bug: ossFuzz:63420
Test: poc in bug
These changes handle the nested bug in the same thread, aborting issue
reported by disabling some code checks which are related to EC.
Bug: ossFuzz:62003
Test: poc in bug
These changes handle the divide-by-zero runtime error
reported when the active lines become zero in
quantization. The issue is reported with AAC and the
same changes are extended to USAC.
Bug: ossFuzz: 62977
Test: poc in bug
These changes handle the index-out-of-bounds runtime error
reported when the bit consumption exceeds the bit reservoir
and global gain reaches the maximum value. The issue is
reported with USAC and the same changes are extended to AAC.

were coming same.
