* master:
Adapt to type parameter added in commons-compress 1.25.0
Improve footer parsing to allow multiline footers.
Make the tests buildable by bazel test
BitmapIndex: Add interface to track bitmaps found (or not)
BitmapWalker: Remove BitmapWalkListener

In 1.25.0 commons-compress added a generic type parameter to
ArchiveOutputStream to avoid unchecked/unconfirmed type casts in
subclasses.

According to the https://git-scm.com/docs/git-interpret-trailers the
CGit supports multiline trailers. Subsequent lines of such multiline
trailers have to start with a whitespace.
We also rewrite the original parsing code to make it easier to work
with. The old code had pointers moving both backwards and forwards at
the same time. In the rewritten code we first find the start of the last
paragraph and then do all the parsing.
Since all the getters of the FooterLine return String, I've considered
rewriting the parsing code to operate on strings. However the original
code seems to be written with the idea, that the data is only lazily
copied in getters and no extra allocations should be performed during
original parsing (ex. during RevWalk). The changed code keeps to this
idea.

All the errorprone checkers fail in many existing places of the
codebase, making it impossible to run bazel test. Downgrade all to
":WARN".
MergeToolTest is asserting a wrong error line, but the line seems
different between bazel and mvn test runs. Therefore we don't fix it and
simply run
```
bazel test -- //... -//org.eclipse.jgit.pgm.test:pgm
```

We want to know what objects had bitmaps in the walk of the
request. We can check their position in the history and evaluate our
bitmap selection algorithm.
Introduce a listener interface to the BitmapIndex to report which
getBitmap() calls returned a bitmap (or not) and a method to the
bitmap index to set the listener.

We can track bitmaps queries that found a bitmap directly in the
BitmapIndex.
Remove the listener.

When a tag with the same name as the branch exists, the branch creation
process should work too. We should detect that the branch already
exists, and allow to force create it when the force option is used.

From errorprone doc: "Dynamically constructed transformation strings
are also flagged, as they may conceal an instance of ECB mode."

Silence the message as a quick relief.

bazel build //org.eclipse.jgit.test:all doesn't build due to
errorprone errors. This leds to disabling the checks and find the
errors later in the jenkins builder.
Fix javadoc errors reported by errorprone. This doesn't fix completely
the build but it is a step towards it.

In this new interface default methods are useful only to instantiate
noop instances. We rather reuse the same noop instance and save the
"default" to add backward compatible methods to existing interfaces.
Make the methods regular interface methods and provide a noop
instance.

During the walk, the commit can be either
1. already in the walk bitmap
2. unvisited so far with bitmap in the bitmap index
3. unvisited so far without bitmap in the bitmap index
Expose these three states in the interface. This makes the interface
easier to explain: it reports the commits found during the walk.
As it is all about commits, rename the methods to onCommit***.

The documentation for TemporaryBuffer::length says:
"The length is only accurate after {@link #close()} has been invoked".
However, we need to have the stream open while accessing the length.
This prevents patches on large files to be applied correctly, as the
result get trimmed.

We want to know what objects had a bitmap in the walk, to see where do
they sit in the commit history and evaluate our bitmap selection
algorithm.
Add a listener interface to the bitmap walker announcing the objects
walked and whether they had bitmap.

Update maven build, bazel build, and target platform.
Also remove a file in a ./bin directory that got committed by mistake
in commit f5f4bf0ad.

By first checking for null-ness and then for the number of strings to
compare we can get rid of a redundant null check.
Change-Id: I0d9a088352c6c1ffea12bc2cded2c63e5293a8a7
Currently for file-based repositories JGit will go over all refs in the
repository forach `ref-prefix` listed in the `ls-refs` command in git
protocol v2 request.
Native git, uses a different approach, where all refs are read once and
then for each ref, all `ref-prefix` filter values are checked in one
pass.
This change implements this approach in JGit only in the `RefDirectory`
backend. And makes `ref-prefix` filtering ~40% faster for repositories
with packed refs.
Different implementations were tested on a synthetic file repository
with 10k refs in `refs/heads/` and `290k` in `refs/changes`. Before
testing `git pack-refs` command was executed. All results are in
seconds.
Current Impl: 39.340 37.093 35.996
Nested for loops: 25.077 24.742 24.748
Nested streams: 24.827 24.890 27.525
Parallel stream + stream: 23.357 23.318 23.174
Nested parallel streams: 23.490 23.318 23.317
Stream + for loop: 23.147 23.210 23.126
Parallel stream + for loop: 23.317 23.423 22.847
The elapsed time was measured around `getRefByPrefix` call in
`Uploadapack.getFilteredRefs(Collection<String>)` (around lines 952 and
954). For testing a modified version of
`UploadPackTest.testV2LsRefsRefPrefix()` was used. The modifications
here included:
* shadowing protected `repo` variable with `FileRepository` pointing
to the synthetic repo with 300k refs described above,
* mimicking the git client clone request by adding `ref-prefix HEAD`,
`ref-prefix refs/heads/` and `ref-prefix refs/tags/`
Based on the above results, the implementation with parallel stream and
stream was selected.

Change [1] reduced the scope of the "writing commit graph" monitoring
task. This left some monitor#update() calls out of any task. When out
of a task, the #update call is a noop.
Delete this update calls as they are noops and misleading.
The affected chunks are usually small and quick to write, so probably
they don't need progress monitoring.
