If multiple threads attempted to insert loose objects into the same new
fan-out directory, the creation of that directory was subject to a race
condition that could lead to an unnecessary IOException being thrown -
because an inserter could not 'create' a directory that had just been
generated by a different thread. All we require is that the directory
does indeed *exist*, so not being able to _create_ it is not actually a
fatal problem. Setting 'skipExisting' to 'true' on the call to mkdir()
fixes the issue.
I found this issue as a real world occurrence while working on The BFG
Repo Cleaner (https://github.com/rtyley/bfg-repo-cleaner), a tool which
concurrently performs a lot of object creation.
In order to demonstrate the problem here I've added a small test case
which reliably reproduces the issue on the few different hardware
systems I've tried. The error thrown when the race-condition arises is
this:
java.io.IOException: Creating directory /home/roberto/repo.git/objects/e6 failed

This is necessary because some versions of JGit containing
the flawed c98abc9c05 were
used in the wild and wrote bad configuration files. We now
must accept this value in addition to the preferred case.

Previously, the FileObjDatabase required both the pack file path and
index file path to be passed to openPack(). A future change to add
a bitmap index will add a .bitmap file parallel to the pack file
(similar to the .idx file). Update the PackFile to support
automatically loading pack index extensions based on the pack file
path.

Once we start talking about parents of tags, we are in the commit
graph, so treat all objects from this point as commits. This fixes
spurious IncorrectObjectTypeExceptions on resolving expressions like
tag^^.

It stopped working when we moved to the Eclipse foundation's Gerrit
server since it doesn't use the Gerrit internal user store but LDAP.
Instead, since 2.0, we use the Eclipse foundation's automatic IP log
generator [1] to generate IP logs for releasing jgit and egit.

FastForwardMode should be represented by different enums depending on
context it is set or get from. E.g. FastForwardMode.FF_ONLY for
branch.<name>.mergeoptions is "--ff-only" but for merge.ff it is "only".

Cherry-pick has been fixed, but even though revert does
basically the same thing, the fixes were not carried over here.
- Recognize the revert-states, analogous to the cherry picking states
- Make reset handle a revert-in-progress
- Update REVERT_HEAD and MERGE_MSG when revert fails due to conflicts
- Clear revert state on commit and reset
- Format the message similarily to how cherry-pick does. This is
not exactly how C Git does it.
The interface is still not the same as for cherry-picking.

These test classes heavily rely on Tree and associated classes. They
are convenient for building test cases and hence not yet replaced, but
there is a deprecation warning at about every line, which is not helpful.

reset() was broken and probably only worked when the position was
at the beginning. More serious was that back() sometimes descended
into the tree rather than skipping backward at the same level. Sometimes
this would result in false conflicts, but one could suspect silent
errors too. back() is called by the NamingConflictTreeWalk when looking
for directory/file conflicts.
Also added toString to DirCacheTree to simplify debugging.

The checkoutPaths body is split into two implementations, depending on
whether we are checking out the index or a branch. This improves
readability, as in the index case we now also need to have access to
DirCacheIterator.

With bug 391855, PathEdit will be changed to apply an edit for each
stage. With that, CommitCommand would no longer work correctly when
committing an unmerged path.
This changes it to use a DirCacheBuilder which allows us to correctly
replace the entries for the three stages with one, which is not possible
with PathEdit.

With bug 391855, DirCacheEditor's PathEdit will be applied for each
stage. For an unmerged path, this would result in 3 equal entries for
the same path.
By using a DirCacheBuilder, the code is simpler and does not have the
above problem with unmerged paths.

For streams that should not be closed, i.e. don't own an underlying
stream, and in-memory streams that do not need to be closed we just
suppress the warning. This mostly apply to test cases. GC is enough.
For streams with external resources (i.e. files) we add the necessary
call to close().

In Iff768422c the offset used for the content id was fixed to use the
offset that applied to the dircache iterator. Unfortunately the index
for the dircache content id offset stuck for entries that were not in
the index. Few caller probably cared about that, unless it actually
caused an ArrayIndexOutOfBoundsException.
