Recursively tries to establish chain from pool of certs starting from certToVerify until a self-signed cert is found, and fill the certs found into chain. Each cert in the chain signs the next one. This method is able to recover from an error, say, if certToVerify is signed by certA but certA has no issuer in certs and itself is not self-signed, the method can try another certB that also signs certToVerify and look for signer of certB, etc, etc. Each cert in chain comes with a label showing its origin.

Params:
