bf3c98815f AUDIO: Add some padding to the QDM2 decoder input buffer 
Fixes out of bounds reads in the Myst ME intro videos.

OOB reads may happen because:
- The bitstream implementation reads 4 bytes at a time, and the buffer
  size is not guaranteed to be a multiple of 4.
- The huffman parsing code reads a fixed amount of bits when it
  sometimes needs not all of them.

Also fixed bits vs bytes mismatch for the size parameter of the calls to
the bitstream constructor, and removed a few unnecessary heap
allocations.

Fixes #10220.

dde259f068 COMMON: Remove BitStream base class to allow inlining calls 
All users of BitStream were in fact using a specific, hardcoded variant,
so we can hardcode that variant, removing the need for virtual calls,
and enabling inlining.

8a5b08341e AUDIO: Remove now unused Sin/Cos table and FFT code from QDM2 Codec. 
This was only used by the RDFT code, now replaced by Common::RDFT.

ce1f805212 AUDIO: Fixes to restore QDM2 Codec function. 
The Bitstream format is changed to 32LELSB and an error in the getVlc2()
function bitstream reading needed to be corrected to fix operation.

50a9c6429d AUDIO: Update to QDM2 codec fixing pointer to stream buffer usage. 
This should allow the QDM2 codec to work again with Common::Bitstream
instead of the older getBits() reader, but this aborts with a reading
past end of stream error...

b5f5cbe5fa AUDIO: Removed qdm2_decode_sub_packet_header() function from QDM2. 
This is to allow modification of the code which needs to assign the
data member of the sub_packet structure to an offset in the input
byte readStream.

845812f12e AUDIO: Fix skipping in QDM2 BitStream usage. 
getBits(n) would cause a runtime error if n is greater than 32,
but using getBits() to skip is no longer necessary as the newer
BitStream class has a skip method, which is used instead.

fa44707028 AUDIO: Initial Refactoring of QDM2 to use Common::BitStream. 
This removes the internal getBitContext bitwise reading code and
replaces with Common::BitStream.

However, this breaks the codec as in one location, the internal buffer
of getBitContext reader is used and this can't be directly replaced.
This will need to be understood and rewritten.

a4798602d7 JANITORIAL: Fix missing whitespace in pointer cast 
find -name '*.h' -or -name '*.cpp' | xargs sed -r -i 's@\(([A-Za-z0-9]+)\*\)@(\1 *)@g'

This seems to have caught some params as well which is not undesirable IMO.
It also caught some strings containing this which is undesirable so I
excluded them manually. (engines/sci/engine/kernel_tables.h)

54f25aa843 COMMON: Renamed Integer Log2 function from log2 to intLog2. 
This avoids naming collisions with system libraries on some platforms
i.e. DS, DC where the log2 is realised by macro.
