SRS-Dolphin is a multiple process solution for SRS.

It's a TCP proxy over ST, which is deprecated. Recommend to use:

1. GO-Oryx, support multiple processes, SRS++.
2. SO_REUSEPORT, directly start multiple SRS to listen at the same port.

For users who want to get srs-dophin code, please checkout to branch feature/deprecated.
