DfsInserter#openStream: Suppress resource warning about DfsReader
DfsReader is not opened in a try-with-resource because in the case where
the method returns an ObjectStream.Filter, the DfsReader should only be
closed from within the Filter's close() method.
Suppress the resource warning.

CloneCommand: Suppress resource warning about Repository
Repository is not opened in try-with-resource because it is wrapped
in a Git instance which should be closed by the caller. On exeptions
during fetch, it is explicitly closed in the catch blocks.
Suppress the warning with an explanatory comment.

Rename RecursiveMergerTest and ResolveMergerTest to reduce confusion
The class names imply that RecursiveMergerTest tests the RecursiveMerger
and ResolveMergerTest tests the ResolveMerger.
In fact, both of them include coverage of both strategies; the difference
is that RecursiveMergerTest is only testing criss-cross merges.
The tests cannot be combined into a single class because the criss-cross
test methods have additional data points.
Instead, rename the classes to more meaningful names.

ResolveMergerTest: Use @DataPoints instead of @DataPoint
Define strategiesUnderTest as an array of MergeStrategy using the
@DataPoints annotation, rather than two separate variables each
annotated as @DataPoint.
This makes the implementation consistent with RecursiveMergerTest.

FS#runProcess: Fix OutputStream left unclosed after IOException
The runProcess method creates an OutputStream that is not managed by
a try-with-resource because it's manually closed and any IOException
raised by the close() method is explicitly ignored.
Suppress the resource warning with an explanatory comment.
Enclose the call to StreamGobbler#copy in an inner try-block, and move
the call to close() inside its finally block. This prevents the stream
from being left unclosed if StreamGobbler#copy raises IOException.

PackWriter: Fix Eclipse errors about missing Javadoc
Change If72b4b422 added a new method filterAndAddObject with a

Teach UploadPack to support filtering by blob size
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.

ObjectIdSerializer: Support serialization of known non-null ObjectId
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.

Add SilentFileInputStream to allow ignoring exceptions raised by close()
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.

Open auto-closeable resources in try-with-resource
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.
