This commit provides an interface for interacting with a QUIC integration TLS functionality. The interface is designed in such a way that allows multiple QUIC integration APIs co-exist in one codebase. It is modelled after the QUIC integration API found in BoringSSL/LibreSSL/QuicTLS and thus makes it easy to make an implementation of the interface for these libraries. Two implementations are planned: 1. A "native" one that uses the QUIC integration API provided by crypto libraries (LibreSSL/QuicTLS). 2. A portable compatibility layer. An API that allows switching between the two at runtime is meant to aid in unit and interoperability testing.
