* Implement AES-GCM cipher support
Fixes#217.
A port of AES-GCM cipher support from Apache MINA-SSHD, based on https://github.com/apache/mina-sshd/pull/132.
Included tests for decoding SSH packets sent from Apache MINA-SSHD and OpenSSH (Version 7.9p1 as used by Debian 10).
Manual tests also done on OpenSSH server 7.9p1 running Debian 10 with its available ciphers, including 3des-cbc, aes128-cbc, aes192-cbc, aes256-cbc, aes128-ctr, aes192-ctr, aes256-ctr, aes128-gcm@openssh.com and aes256-gcm@openssh.com.
* Changes per PR feedback
- Fixed variable/statement whitespaces and add back missing braces per coding standard requirement
- Moved Buffer.putLong() and Buffer.getLong() into GcmCipher.CounterGCMParameterSpec since it's the only user
- Moved BaseCipher.authSize into GcmCipher since it is the only cipher that would return a non-zero. BaseCipher will keep return 0 instead
- Made BaseCipher.cipher protected instead of making it publicly accessible
- Combined the three decoding modes in Decoder.decode() into one single method, to reduce code duplication
- Added integration test for the ciphers, along with the newly implemented AES-GCM ciphers
* Fix RSA certificate key determination.
Fixes#599.
* Correct serialization of RSA certificates with unlimited dates.
* The test for connecting with RSA certificate.
* Remove redundant change in TransportImpl.java
* Add forgotten test keys.
* Make net.schmizz.sshj.common.KeyType.CertUtils.epochFromDate readable.

* Fix matching of pubkeys to key algorithms
Allow all configured key algorithms for pubkey authentication, even if
these algorithms are not supported as host key algorithms by the
server.
Preference is given to the modern rsa-sha2-* signature algorithms if
the server indicates support for them as host keys signature
algorithms.
* Replace Boolean with primitive boolean
* Add integration tests for ecdsa-sha2-nistp384/521
* Remove redundant import
* Clean up Transport interface

* Added support for RSA to openssh-key-v1 keyfile
* Fixed exception
* Added ECDSA support to openssh-key-v1
* Added integration tests for different keytypes
