Teach UploadPack to advertise the filter capability and support a
"filter" line in the request, accepting blob sizes only, if the
configuration variable "uploadpack.allowfilter" is true. This feature is
currently in the "master" branch of Git, and as of the time of writing,
this feature is to be released in Git 2.17.
This is incomplete in that the filter-by-sparse-specification feature
also supported by Git is not included in this patch.
If a JGit server were to be patched with this commit, and a repository
on that server configured with RequestPolicy.ANY or
RequestPolicy.REACHABLE_COMMIT_TIP, a Git client built from the "master"
branch would be able to perform a partial clone.

The implementation of ObjectIdSerializer, added in change I7599cf8bd,
is not equivalent to the original implementation in Gerrit [1].
The Gerrit implementation provides separate methods to (de)serialize
instances of ObjectId that are known to be non-null. In these methods,
no "marker" is written to the stream. Replacing Gerrit's implementation
with ObjectIdSerializer [2] broke persistent caches because it started
writing markers where they were not expected [3].
Since ObjectIdSerializer is included in JGit 4.11 we can't change the
existing #write and #read methods. Keep those as-is, but extend the
Javadoc to clarify that they support possibly null ObjectId instances.
Add new methods #writeWithoutMarker and #readWithoutMarker to support
the cases where the ObjectId is known to be non-null and the marker
should not be written to the serialization stream.
Also:
- Replace the hard-coded `0` and `1` markers with constants that can
be linked from the Javadocs.
- Include the marker value in the "Invalid flag before ObjectId"
exception message.

Refactor getBitmapIndex to open ReadableChannel in try-with-resource
instead of closing the channel in the finally block.
The same cannot be done in copyPackThroughCache, so just suppress the
warning with an explanatory comment.

In #writeTo, the TemporaryBuffer can't be opened in try-with-resource
because it's referenced in the finally block. Instead it is explicitly
closed within the try block. Suppress the warning with an explanatory

There are several cases where a FileInputStream is opened outside of
a try-with-resource because we want to explicitly close it and ignore
any IOException that is raised by the close() method.
Introduce a helper class, SilentFileInputStream, that overrides the
close method and ignores the exceptions. This allows to open the stream
in a try-with-resource block and remove the explicit handling of the
close method.

PackWriter is auto-closeable and should be opened in try-with-resource,
but this is not possible since the variable is being referenced in the
finally block before being explicitly closed there.

Remove the resource warning suppression and refactor the code to open

SubmoduleWalk is auto-closeable, and Eclipse warns that is is not
managed by try-with-resource. However in this case the resource should
not be closed, because the caller needs to use it. Instead, it is the
responsibility of the caller to close it after use.
Update the Javadoc to clarify this, and suppress the warning.

In most of the tests, the temporary buffer is explicitly destroyed in
a finally block after being closed. This is not possible if using the
try-with-resource construct, because the variable is not accessible in
the finally block scope.

When an auto-closeable resources is not opened in try-with-resource,
the warning "should be managed by try-with-resource" is emitted by
Eclipse.
Fix the ones that can be silenced simply by moving the declaration of
the variable into a try-with-resource.
In cases where we explicitly call the close() method, for example in
tests where we are testing specific behavior caused by the close(),
suppress the warning.
Leave the ones that will require more significant refcactoring to fix.
They can be done in separate commits that can be reviewed and tested
in isolation.

Move the code from ConfigureGerritAfterCloneTask to SshSupport and
eliminate the slightly modified copy of the code from
LfsConnectionFactory. Separate EGit commit will eliminate the code from
ConfigureGerritAfterCloneTask.

StreamCopyThread: Do not let flush interrupt a write.
flush calls interrupt() to interrupt a pending read and trigger a
flush. Unfortunately that interrupt() call can also interrupt a
pending write, putting Jsch in a bad state and triggering "Short read
of block" errors.

Use Java 8 BufferedOutputStream instead. Java 8 fixed the silent flush
during close issue by FilterOutputStream (base class of
BufferedOutputStream) using try-with-resources to close the stream,
getting a behavior matching what JGit's SafeBufferedOutputStream
was doing
