Check whether the value of the git config user.signingKey is a suffix
of the full fingerprint of the key. This was already used for finding
keys in secring.gpg, but not in pubring.kbx. This mechanism allows a
user to use any unique suffix to identify keys; to avoid needless
collisions it's recommended to use at least the last 16 characters of
the hex representation of the fingerprint, which is the key id.[1]

4e196faa1b ("ReachabilityChecker: Default implementation with a
RevWalk", 2019-05-15) added ReachabilityCheckerTestCase but did not add
it as a test helper in the corresponding BUILD file, making tests no
longer runnable with Bazel. Resolve this issue.

In 7b96bd812e ("UploadPack: Use reachability checker to validate
non-advertised wants", 2019-05-16), a "walk.setRetainBody(false);"
statement was inadvertently deleted. (An earlier version of this commit
had this line in another part of the code and a review comment suggested
to move it back here; the line was then deleted from the other part of
the code but not readded.) Restore this line.

UploadPack: Use reachability checker to validate non-advertised wants
BitmappedReachabilityChecker: Reachability check using bitmaps
BitmapCalculator: Get the reachability bitmap of a commit
ReachabilityChecker: Default implementation with a RevWalk
In "Reachable commit" request validators, we need to check that a "want"
in the request, that hasn't been advertised, is reachable from the refs
visible to the user.
Current code has intermixed the translation of ObjectIds to RevCommits
(and its error handling) with the actual walk, with the delegation to
bitmaps in restricted circunstances.
Refactor the code to make it "flatter" and more readable. Move ObjectIds
to RevCommits translation to its own functions. Use the reachability
checker instead of a newly defined walk.
Before the non-advertised wants were validated with bitmaps only if any
"want" refered to an non-commit. Now they will be validated with bitmaps
also if the "wants" refer all to commits.

The "basic" reachability check walks the graph starting from the tips
marking things as "uninteresting". If the target commit is marked as
"uninteresting" it was reached; it is reachable from those tips.
This requires a lot of walking and can be solved directly with bitmaps.
Most of the time the bitmaps are already calculated or a short walk
away.
This should improve the performance of reachability checks, for example
in Gitiles.

To make reachability checks with bitmaps, we need to get the
reachability bitmap of a commit, which is not always precalculated.
There is already a class returning such bitmap (BitmapWalker) but it
does too much unnecessary work: it calculates ALL reachable objects from
a commit (i.e. including trees and blobs), when for reachability the
commits are just enough.
Introduce BitmapCalculator to get the bitmap of a commit: either because
it is precalculated or generating it with a walk only over commits.

It is common to check if a certain commit is reachable from some
starting points. For example gitiles does it to check if a commit
is visible to a user based on its permissions.
Offer this functionality in JGit.
Split the interface as the next commit will introduce an implementation
using bitmap indices.

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.

Making gitlinks and folders match in a tree walk was the wrong
approach to fix bug 467631. The problem is that in such a conflict
the tree walk may then not descend into the folder.
Revert the changes to Paths.java and PathsTest.java from commit
4678f4b. Instead test for the problem case from bug 467631 explicitly
in IndexDiff. Add Daniel's test case from bug 545162, and add yet
another test case for DiffEntry.scan() that covers the problem
originally reported in bug 545162.

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.
