Collection of fixes in EVS part

This issue is intended to organize possible fixes/CRs to EVS based on changes done on the EVS part of the IVAS floating point code. Related fixes with links to issues and/or merge requests should be added to the list below.

Note that the list of BASOP-only fixes can be found sa4/audio/ivas-basop#1292.

• #1328 (closed)
• #1279 (closed) - fixed both in EVS and IVAS formats (it is a non-BE change that pops up in very long test files only)
• #1277 (closed) - related to FLP only; fixed in IVAS formats
• #1244
• #1180 - fixed in IVAS formats
• #1130 (closed) - fixed in IVAS formats
• #1118 (closed)
• #1038 (closed) - already fixed in IVAS code with !1485 (merged). Not strictly necessary to port to EVS.
• #1037 (closed) - !1498 (merged) pending review
• #1036 - Not strictly necessary to port to EVS.
• #1027 (closed)
• #970 (closed) - !1497 (merged) pending review/decision
• #575
• #548 - already fixed in IVAS but not in EVS.
• #517 - fixed in IVAS formats
• #23
• #1132 (closed) - !1670 (merged) (the issue is present only in the floating-point code and not in the fixed-point code. While it might be possible to adopt the fix from the fixed-point code, it was deemed too risky as it leads to several hundreds of non-bit-exact cases. Therefore, a different fix has been implemented.)

There is also a list of currently suppressed USAN errors in #630 - all of them are in the EVS part of IVAS.
