The bundle org.eclipse.jgit.java7 was removed in 4.0.
Remove references to it from the README.md.
Remove reference to it from org.eclipse.jgit.test/.project, which
causes an error message when opening the project in Eclipse:

DepthWalk needs to override toObjectWalkWithSameObjects() and thus
needs to be able to directly set the objects and freeFlags fields, so
make them package private.

When doing an incremental fetch from JGit, "have" commits are marked
as "uninteresting". In a non-shallow fetch, when the RevWalk hits an
"uninteresting" commit it marks the commit's corresponding tree as
uninteresting. That has the effect of dropping those trees and all the
trees and blobs they reference out of the thin pack returned to the
client.
However, shallow fetches use a DepthWalk to limit the RevWalk, which
nearly always causes the RevWalk to terminate before encountering the
"have" commits. As a result the pack created for the incremental fetch
never encounters "uninteresting" tree objects and thus includes
duplicate objects that it knows the client already has.

to have more control over determination of the backend, for example:
- return different backends for different requests
- accept or refuse requests based on request characteristics
- etc

The message "close() called when useCnt is already zero" is logged with
level warning, and then if debug logging is enabled, the stack trace is
logged separately with level debug.
Log the message and the stack trace in the same call, so that they always
appear together in the output rather than potentially interleaved with
other log statements.

This prevents the warning:
Potential heap pollution via varargs parameter
The method doesn't do any casting of types that would cause the heap
pollution, so it should be safe to add @SafeVarArgs.
See [1] for information about this warning.

Gerrit's superproject subscription feature uses RefSpecs to formalize
the ACLs of when the superproject subscription feature is allowed.
As this is a slightly different use case than describing a local/remote
pair of refs, we need to be more permissive. Specifically we want to allow:
refs/heads/*
refs/heads/*:refs/heads/master
refs/heads/master:refs/heads/*
Introduce a new constructor, that allows constructing these RefSpecs.

We had a case in Gerrits superproject subscriptions where
'refs/heads/' was configured with the intention to mean 'refs/heads/*'.
The first expression lacks the '*', which is why it is not considered
a wildcard but it was considered valid and so was not found early to be
a typo.
Refs are not allowed to end with '/' anyway, so add a check for that.

What's invalidated when an object database is "dirty" is not the whole
database, but rather a specific list of packs. If there is a race
between getting the pack list and setting the volatile dirty flag
where the packs are rescanned, we don't need to mark the new pack list
as dirty.
This is a fine point that only really applies if the decision of
whether or not to mark dirty actually requires introspecting the pack
list (say, its timestamps). The general operation of "take whatever
is the current pack list and mark it dirty" may still be inherently
racy, but the cost is not so high.

9aa3748 added dummy implementations for loadRoleInfo() and
loadUserInfo() to class MappedLoginService to fix compile errors in
Eclipse when using 4.6 target platform which brings Jetty 9.3 adding
these two methods. Unfortunately this causes errors when using non 4.6
target platform coming with an older Jetty version. Fix this by
extracting the anonymous subclass of MappedLoginService which allows to
suppress the unused private method errors in Eclipse.

Currently, there is a race where a user of a DfsRepository in a single
thread may get unexpected MissingObjectExceptions trying to look up an
object that appears as the current value of a ref:
1. Thread A scans packs before scanning refs, for example by reading
an object by SHA-1.
2. Thread B flushes an object and updates a ref to point to that
object.
3. Thread A looks up the ref updated in (2). Since it is scanning refs
for the first time, it sees the new object SHA-1.
4. Thread A tries to read the object it found in (3), using the cached
pack list it got from (1). The object appears missing.
Allow implementations to work around this by marking the object
database's current pack list as "dirty." A dirty pack list means that
DfsReader will rescan packs and try again if a requested object is
missing. Implementations should mark objects as dirty any time the ref
database reads or scans refs that might be newer than a previously
cached pack list.

When Repository.close() decrements the useCount to 0 currently the cache
immediately evicts the repository from WindowCache and RepositoryCache.
This leads to I/O overhead on busy repositories because pack files and
references are inserted and deleted from the cache frequently.
This commit defers the eviction of a repository from the caches until
last use of the repository is older than time to live. The eviction is
handled by a background task running periodically.
Add two new configuration parameters:
* core.repositoryCacheExpireAfter: cache entries are evicted if the
cache entry wasn't accessed longer than this time in milliseconds
* core.repositoryCacheCleanupDelay: defines the interval in milliseconds
for running a background task evicting expired cache entries. If set to
-1 the delay is set to min(repositoryCacheExpireAfter, 10 minutes). If
set to 0 the time based eviction is switched off and no background task
is started. If time based eviction is switched off the JVM can still
evict cache entries if heap memory is running low.

These try-with-resources blocks close the underlying output stream
twice: once when closing the CountingOutputStream wrapper, then again
when closing the DfsOutputStream out.
Simplify by only closing the CountingOutputStream.
In practice this shouldn't matter because the close() method of a
Closable is required to be idempotent, but avoiding the redundant
extra close makes the code simpler to read and understand.

If the client sent a well-formed enough request to see it wants to use
side-band-64k for status reporting (meaning its a modern client), but
any other command record was somehow invalid (e.g. corrupt SHA-1)
report the parsing exception using channel 3. This allows clients to
see the failure and know the server will not be continuing.
git-core and JGit clients send all commands and then start a sideband
demux before sending the pack. By consuming all commands first we get
the client into a state where it can see and respond to the channel 3
server failure.
This behavior is useful on HTTPS connections when the client is buggy
and sent a corrupt command, but still managed to request side-band-64k
in the first line.

Instead of deferring until after command parsing, enable the
capabilities after the first pkt-line has been read from the client.
This allows the server to setup the side-band-64k channel immediately.

If the push client has requested side-band support the server can
signal a fatal error parsing the pack using the error channel (3)
and then hang up. This may cause the PackWriter to fail to write to
data onto the network socket, which throws a misleading error back
up to the application and the user.
During a write failure poll the input to see if the side band system
can parse out an error message off channel 3. This should be fast as
there will either be an error present in the buffer, or the remote will
also have hung-up on the side band channel. In the case of a hang-up
just rethrow the original IOException as its a network error.
This roughly matches what C git does; once commands are sent and the
packer is started a new thread runs in the background to decode any
possible server error during unpacking on the remote peer

A RefAdvertiser writing to the network includes both the reference's
