Name bouncy castle libraries consistently. This also allows to use
local jgit tree as dependency in gerrit.

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.

This also includes a change to generating the jgit CLI jar. Shading is
no longer possible because it breaks the signature of BouncyCastle.
Instead, the Spring Boot Loader Maven plug-in is now used to generate an
executable jar.

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.

Create the bundle and move the SshTestGitServer there. Verified that
the Eclipse build still works and ran JSchSshTest and ApacheSshTest as
junit tests inside Eclipse.

Update maven build and features to account for that. Verified by
running full maven build including packaging.

Update bazel build files to account for that. Verified by a
clean-slate bazel build :all, followed by running the JSchSshTest
and the ApacheSshTest via bazel.

Add a new ssh client implementation based on Apach MINA sshd 2.0.0.

This implementation uses JGit's own config file parser and host entry
resolver. Code inspection of the Apache MINA implementation revealed
a few bugs or idiosyncrasies that immediately would re-introduce bugs
already fixed in the past in JGit.

Apache MINA sshd is not without quirks either, and I had to configure
and override more than I had expected. But at least it was all doable
in clean ways.

Apache MINA boasts support for Bouncy Castle, so in theory this should
open the way to using more ssh key algorithms, such as ed25519.

The implementation is in a separate bundle and is still not used in
the core org.eclipse.jgit bundle. The tests re-use the ssh tests from
the core test bundle.

Add a simple ssh git server based on Apache MINA sshd, and use it
in new tests that verify ssh operations and in particular a number
of bugs that had cropped up over time in JSch.

The git server supports fetching only, and sftp access.

The tests are all in an abstract base class; the concrete JschSshTest
class only provides ssh-specific test setup. So the same tests could
be run easily also with some other ssh client.

Recent Bazel versions support the hyphen character in external
repository names. On the Gerrit project, the repository names
were harmonized to consistently use hyphen.

As a side effect, it is no longer possible to build jgit from source
in the gerrit tree, due to the different repository names.

Rename the dependencies to use hyphens, consistent with gerrit.

Only testonly targets (such as tests) need to use junit.

In particular this involves making the toplevel :all rule testonly.
It's not clear to me what that rule is for --- "bazel build //..."
already works to build all targets.  In any case it appears to be for
testing, so marking it as testonly shouldn't be harmful.

This provides a place to declare visibility restrictions and
transitive dependencies for each library.

Other targets should only declare dependencies on what they directly
use, making dependencies easier to maintain.

Trim the dependencies of org.eclipse.jgit:jgit to follow that rule.
It declares dependencies on Apache httpcomponents and the servlet
API but doesn't use them.

Tested:
* 'bazel build //...' succeeds
* applying the change https://gerrit-review.googlesource.com/90843
  to a copy of Gerrit, following the instructions there, and running
  'bazel test //...' in that copy of Gerrit still succeeds
