RingBuffer: initial commit
Implements a ring buffer class for LMMS, which is designed to be flexible, efficient and thread-safe.
Due to flexible design, it supports various methods of operation:
- set delays/sizes in absolute frame values, ignoring samplerate
- set delays/sizes in milliseconds with samplerate-awareness
- multiple inputs -> single output
- single input -> multiple outputs
Efficiency is achieved by working in buffers and using memcpy/memset for audio operations, except when additive mixing is needed: then MixHelpers are used
Thread-safety is guaranteed with QMutex
