When building the library with NDEBUG, asserts are eliminated so it's better to always check that the number of coefficients is inside the array range. This fixes the 00191-audiofile-indexoob issue in mpruett#41
Check for multiplication overflow (using __builtin_mul_overflow if available) in MSADPCM.cpp decodeSample and return an empty decoded block if an error occurs. This fixes the 00193-audiofile-signintoverflow-MSADPCM case of mpruett#41
Checks that a multiplication doesn't overflow when calculating the buffer size, and if it overflows, reduce the buffer size instead of failing. This fixes the 00192-audiofile-signintoverflow-sfconvert case in mpruett#41

Why is the assert statement still needed in this case?

Well, in case the code is built with DEBUG defined (as I guess @mpruett does) the assert would fail and I didn't want to change that behavior for the main developer. Also, in the general case (when DEBUG is not defined, as most distributions build this code), the assert is already a NOP.
