We currently cannot use hamcrest 2.2 and assertj 3.20.2 (which requires
hamcrest 2.2) in egit tests since other Eclipse dependencies (e.g.
swtbot) require hamcrest 1.1.
Hence relax version range for these components in jgit so that jgit
tests also work when using the egit target platform.

and update
- assertj to 3.20.2.v20210706-1104
- hamcrest to 2.2.0.v20210711-0821
- classes which were in org.hamcrest.core 1.3 and org.hamcrest.library
1.3 were all moved to org.hamcrest in 2.2
- the annotation org.hamcrest.Factory was removed and is no longer
needed
- junit 4.13 requires hamcrest-core and hamcrest-library 1.3 therefore
keep them in the target platform

Make the used KEX algorithms configurable via the ssh config. Also
implement adding algorithms not in the default set: since sshd 2.6.0
deprecated SHA1-based algorithms, it is possible that the default set
has not all available algorithms, so adding algorithms makes sense.
This enables users who have to use a git server that only supports
old SHA1-based key exchange methods to enable those methods in the
ssh config:
KexAlgorithms +diffie-hellman-group1-sha1
There are two more SHA1 algorithms that are not enabled by default:
diffie-hellman-group14-sha1 and diffie-hellman-group-exchange-sha1.
KeyAlgorithms accepts a comma-separated list of algorithm names.
Since adding algorithms is now supported, adapt the handling of
signature algorithms, too. Make sure that definitions for the KEX
exchange signature (HostKeyAlgorithms) don't conflict with the
definition for signatures for pubkey auth (PubkeyAcceptedAlgorithms).
HostKeyAlgorithms updates the signature factories set on the session
to include the default factories plus any that might have been added
via the SSH config. Move the handling of PubkeyAcceptedAlgorithms
from the client to the JGitPubkeyAuthentication, where it can be done
only if pubkey auth is attempted at all and where it can store its
adapted list of factories locally.

Apache MINA sshd 2.6.0 appears to use only the first appropriate
public key signature algorithm for a particular key. See [1]. For
RSA keys, that is rsa-sha2-512. This breaks authentication at servers
that only know the older (and deprecated) ssh-rsa algorithm.
With PubkeyAcceptedAlgorithms, users can re-order algorithms in
the ssh config file per host, if needed. Setting
PubkeyAcceptedAlgorithms ^ssh-rsa
will put "ssh-rsa" at the front of the list of algorithms, and then
authentication at such servers with RSA keys works again.

Re-enable DSA, DSA_CERT, and RSA_CERT public key authentication.
DSA is discouraged for a long time already, but it might still be
way too disruptive to completely drop it. RSA is discouraged for
far less long, and dropping that would be really disruptive.
Adapt to the changed property handling. Remove work-arounds for
shortcomings of earlier sshd versions.
Use Orbit I20210203173513, which includes sshd 2.6.0. This also bumps
apache.httpclient to 4.5.13 and apache.httpcore to 4.4.14.

This is useful to access git repositories behind a bastion server
(jump host).
Add a constant for the config; rewrite the whole connection initiation
to parse the value and (recursively) set up the chain of hops. Add
tests for a single hop and two different ways to configure a two-hop
chain.
The connection timeout applies to each hop in the chain individually.

Motivation: JSch serves as 'default' implementations of the SSH
transport. If a client application does not use it then there is no need
to pull in this dependency.
Move the classes depending on JSch to an OSGi fragment extending the
org.eclipse.jgit bundle and keep them in the same package as before
since moving them to another package would break API. Defer moving them
to a separate package to the next major release.
Add a new feature org.eclipse.jgit.ssh.jsch feature to enable
installation. With that users can now decide which of the ssh client
integrations (JCraft JSch or Apache Mina SSHD) they want to install.
We will remove the JCraft JSch integration in a later step due to the
reasons discussed in bug 520927.

RFC 4253 section 4.2 allows an ssh server to send additional lines
before its server identification string. Apache MINA sshd enforces
for these lines the constraints specified for the server identification
line, too: no NUL characters and not longer than 255 characters. That
is too strict. RFC 4253 doesn't mandate this, and it also doesn't
make sense given the rationale for these lines in RFC 4253: a TCP
wrapper may not be aware of SSH restrictions, and may not adhere to
these constraints.
Be more lenient when parsing the server's protocol version. Allow
NULs and longer lines in the preamble, and also handle line endings
more leniently. Only enforce the restrictions for the actual server
identification line.
