For ossrs#2532: Windows: Support CYGWIN64 for SRS

1. Support cygwin by '--cygwin64=on' 2. Detect cygwin automatically. 3. Disalbe sanitizer, srt and srtp with openssl. 4. Disable multiple threads, use single threads. 5. Support utest for cygwin64. 6. Query features for windows by API. 7. Disable stat APIs for cygwin. 8. Use ST select event driver.
