WalkFetchConnection: Remove marked packs on all function exits
[1] replaces Iterator.remove() with a list of "toRemove" that gets
processed when returning at the end. There are two others returns in
the function where the list is not processed.
Let the method report the broken packages and wrap it so the caller
can clean them up in any case.
In https://gerrithub.io/c/eclipse-jgit/jgit/+/1194015, LinkedList was
replaced with ArrayList in DfsReader and WalkFetchConnection. In this
case, the Iterator.remove() method of List is called, which is an O(n)
operation for ArrayList. This results in an O(n^2) algorithm.
Instead of reverting to LinkedList, use a HashSet and LinkedHashmap
instead. This maintains O(1) removal, and is less likely to be treated
as an antipattern than LinkedList.
A likely innocuous usage of Iterator.remove() in UnionInputStream was
also fixed.

Allow applying a patch with conflicts
In some settings, we want to let users apply a patch that does
not cleanly apply and add conflict markers. In Gerrit, this is
useful when cherry picking (via Git patches) from one host to
another.
This commit takes a simple approach: If a hunk doesn't apply,
go to the pre-image line, treat all lines in pre-image length
as left side of the conflict and all context and newly added
lines as right side of the conflict.

sshd: fix IdentiesOnly if SSH agent is enabled and has keys
Commit a44b9e8bf changed the logic so that we try to read a public key
from the file given first, and only then try the file with the ".pub"
extension. Unfortunately the exception handling was not sufficient to
correctly deal with the given file containing a private key.
Apache MINA SSHD may throw a StreamCorruptedException when one tries
to read a public key from a file containing a private key. Handle
this exception in addition to GeneralSecurityException, and change
the order of exception handlers because StreamCorruptedException is
an IOException.

PackIndex: Make iterator static (pass object count in ctor)

Bazel: Add support for JDK 21
There are two failing tests when switching to JDK 21.
One failure is related to the changed behaviour related to the locale
providers. Adapt `GitDateFormatterTest` to changes in unicode [1].
Second failure related to changed behaviour in URL.openConnection(),
see: [2] for more details.
Before JDK 20, some of the parsing/validation performed by the JDK
built-in URLStreamHander implementations were delayed until
URL::openConnection or URLConnection::connect was called. Starting
JDK 20, some of these parsing/validations are now performed early,
i.e. within URL constructors.
IOW, the assumption made in HttpSupport.TesttestMalformedUri() isn't
met any more: providing mailformed URI to the URL ctor now throws an
exception starting with JDK 20. To rectify the problem, remove the
offending test.
Test plan:
To build with JDK 21 and run the tests locally:
$> bazel test --config=java21 //...
To build with JDK 21 and run the tests on RBE:
$> bazel test --config=remote21 --remote_instance_name=$PROJECT //...

PackBitmapIndexBuilder.StoredEntry: add getter for objectId
If you only have access to the PackBitmapIndexBuilder there is no way to
get the ObjectId from a StoredEntry instance without also having access
to a reverse pack index. The StoredEntry can provide the idxPosition,
but the PackBitmapIndexBuilder's getObject method requires a
ridxPosition in order to find an ObjectId.
Providing an ObjectId from the StoredEntry gives this information
directly and also allows a caller to get the ridxPosition if desired by
calling PackBitmapIndexBuilder.findPosition(objectId) without needing
an index object.
This closes the operations of the PackBitmapIndexBuilder such that any
method can be called by using information provided by the other methods.

The documentation for the getObject function seems to be a little

The previous code computed the boundaries of the base part of

'theirs' revisions, leading to incorrect boundaries.
This only affects the presentation of merge conflicts in diff3

CleanupService: preload JgitText if not running in OSGi
Load class JGitText eagerly when ShutdownHook is used. If not running

classloading in a shutdown hook should not be a problem, but there are
some other frameworks besides OSGi that may close classloaders before
such a JVM shutdown hook runs, for instance Plexus classworlds used in
maven.
This is not a full fix for classloading problems in JGit shutdown hooks.
If a listener causes additional classes to be loaded, there may still
be problems. But the current listeners registered with ShutdownHook all
appear to use only classes that should already be loaded; except
JGitText.
