[sshd] Correct signature for RSA keys from an SSH agent
Ensure that there is always a list of signature factories in public key
authentication. For keys loaded directly, Apache MINA sshd will use the
(always set) list from the SSH session by default, but for keys from an
SSH agent it won't and instead consider the list set locally on the
UserAuthPublicKey instance. Only that one is null by default, and then
Apache MINA sshd just uses the key type as signature type. Which for
RSA keys from an agent is the "ssh-rsa" signature, i.e., the deprecated
SHA1 signature.
Fix this by explicitly propagating the list from the session to the
UserAuthPublicKey instance if not set already.

When bitmaps are not enabled the RevWalk is expensive. AllowFilter

HTTP Smart: set correct HTTP status on error
Previous behavior was that status code was automatically set to 200

respond with 200 OK response. A server SHOULD respond with

HttpConnection does not expose HttpURLConnection#getErrorStream) the

[sshd] Better user feedback on authentication failure
When authentication fails, JGit produces an exception with an error
message telling the user that it could not log in (including the host
name). The causal chain has an SshException from Apache MINA sshd with
message "No more authentication methods available".
This is not very helpful. The user was left without any indication why
authentication failed.
Include in the exception message a log of all attempted authentications.
That way, the user can see which keys were tried, in which order and
with which signature algorithms. The log also reports authentication
attempts for gssapi-with-mic or password authentication. For
keyboard-interactive Apache MINA sshd is lacking a callback interface.
The way Apache MINA sshd loads keys from files, the file names are lost
in higher layers. Add a mechanism to record on the session for each
key fingerprint the file it was loaded from, if any. That way the
exception message can refer to keys by file name, which is easier to
understand by users than the rather cryptic key fingerprints.

[push, lfs] Tell the pre-push hook whether the push is a dry run
This is a feature that does not exist in C git: an external pre-push
hook doesn't know whether the push is run as a dry run. But for
internal hooks written in Java it is entirely possible to give a hook
this information.
In JGit with its internal LFS implementation, this enables us to not
perform LFS uploads in a dry run. This is kind of important because
EGit frequently does a dry-run before doing the actual push to give the
user a way to review what would be pushed before it actually happens.
Doing an LFS upload of potentially huge files during a dry-run is
wasteful, makes the dry run not actually a dry run, and leads to
uploading the same file twice if followed by a real push.
Use the information in the LfsPrePushHook to only do the initial call
to the LFS server, but then skipping the actual upload if the push is
a dry run. That way, a failure to contact the LFS server leads to an
error in the dry run, as it should.
