I tested all fingerprints and confirmed that Chrome and Firefox are
working as intended.
Android fingerprints were grossly unpopular, which could a result of
incorrect merge, but either way we'll remove them for now.
The root cause of races is that global variables supportedSignatureAlgorithms and
cipherSuites are used both to form handshake and to check whether or not
peer responded with supported algorithm.
In this patch I create separate variables for this purpose.
Updated tests for kicks.
Finally, go fmt.
