Add encrypted ed25519 keys in the tests; sshd 2.2.0 can finally
decrypt encrypted new-style OpenSSH key files. (Needs the "unlimited
strength" JCE, which is the default since Java 8u161. On older JREs,
users should install the policy files available from Oracle.)
The "expensive" key added has been generated with OpenSSH's
ssh-keygen -t ed25519 -a 256, i.e., with 256 bcrypt KDF rounds
instead of the default 16. On my machine it takes about 2sec to
decrypt.

Update target platforms, maven and bazel builds to use sshd 2.2.0.
Adapt internal classes to changed sshd interfaces and remove previous
work-arounds for asking repeatedly for key passwords and for loading
keys lazily; both are now done by sshd.

The message delaying for the initial SSH messages (client
identification followed by the initial key exchange request)
was broken. sendKexInit() is _also_ called when a new key exchange
is requested. We inadvertently also re-sent the client identification
at that point, which is wrong and makes the server terminate the
connection.
Re-keying occurs from time to time during an SSH connection depending
on time, the number of messages (packets/blocks) exchanged, or the
amount of data exchanged. The net result was that for large
repositories data-intensive operations failed on the first re-keying.
Change the initial message delay such that the two messages for the
client identification and the initial key exchange can be buffered
individually while the proxy protocol is still in progress. The
AbstractClientProxyConnector can now buffer several commands, which
should also resolve bug 544715.

Provide a mechanism for a subclass to provide its own set
of default identities from anywhere as an Iterable<KeyPair>.
The default implementation is functionally unchanged and uses
the known default identity files in the ~/.ssh directory. A subclass
can override the getDefaultKeys() function and return whatever keys
are appropriate.

Don't use the ~/.ssh directory as cache key for the key provider
but the configured paths of the default keys. Otherwise changes
in that list of paths are not picked up.
This is in particular a problem for EGit, where the user can modify
this list of keys interactively in the preferences. Without this
change, Eclipse needs to be restarted to pick up such changes.

In the original contribution of this bundle, japicmp was disabled
as no previous version to compare against existed. Enable it now.
Update the version to compare against to 5.2.0.201812061821-r.

Include the net.i2p.crypto.eddsa bundle via a hard dependency.
Add tests for dealing with ed25519 host keys and user key files.
Manual tests: fetching from git.eclipse.org with an ed25519 user key,
and pushing this change itself using the same ed25519 key.
Note that sshd 2.0.0 does not yet support encrypted ed25519 private
keys.
