aac project forces the system not to include sys/types.h by defining
_SYS_TYPES_H_. This is a workaround for broken android toolchain.
This is no longer needed in latest android version and can be safely
removed. This will also lead to more errors if changes in bionic
headers are needed.

Shifting by more than (or equal to) the variable length is
undefined in C.
This caused the quantized spectrum values to go out of range,
triggering asserts later.
