Function name: jpegd_show_bits
Functional description:
Reads 32 bits from stream and returns the bits, does not update
stream pointers. If there are not enough bits in data buffer it
reads the rest of the data buffer bits and fills the lsb of return
value with zero bits.
Note! This function will skip the byte valued 0x00 if the previous
byte value was 0xFF!!!
Inputs:
StreamStorage *pStream Pointer to structure
Outputs:
Returns 32 bit value
