Motivation:
Some SSLEngine implementations violate the contract and raises an
exception when SslHandler feeds an input buffer that contains multiple
SSL records to SSLEngine.unwrap(), while the expected behavior is to
decode the first record and return.
Modification:
- Modify SslHandler.decode() to keep the lengths of each record and feed
SSLEngine.unwrap() record by record to work around the forementioned
issue.
- Rename unwrap() to unwrapMultiple() and unwrapNonApp()
- Rename unwrap0() to unwrapSingle()
Result:
SslHandler now works OpenSSLEngine from finagle-native. Performance
impact remains unnoticeable. Slightly better readability. Fixes#2116.
