This has the same logic as isNameConflicting, but instead of only
returning a boolean, it returns a collection of names that conflict.
It will be used in EGit to provide a better message to the user when
validating a ref name, see Ibea9984121ae88c488858b8a8e73b593195b15e0.
Existing implementations of isNameConflicting could be rewritten like
this:
return !getConflictingNames(name).isEmpty();
But I'm not sure about that, as isNameConflicting can be implemented in
a faster way than getConflictingNames.

Instead of the complicated strange stuff, implement staah

Provided there are no conflicts and it is requested that
the index should be applied, perform yet another cherry-pick,
but discard tha results thereof it that would result in conflicts.

getObjectList() returns a list of ObjectToPack. These can hold on to a
lot of memory. Furthermore, binary searching for objects in a sorted
array can be slow. Improve the speed and reduce the memory by creating a
copy of the ObjectId and inserting it into an ObjectIdOwnerMap.

This adds a new optional TreeFilter[] argument to DiffEntry.scan. All
filters will be checked during the scan to determine if an entry should
be "marked" with regard to that filter.
After having called scan, the user can then call isMarked(int) on the
entries to find out whether they matched the TreeFilter with the passed
index.
An example use case for this is in the file diff viewer of EGit's
History view, where we'd like to highlight entries that are matching the
current filter.

In case of a conflict during cherry-pick or revert the commit message

Previously the result of an application would have been \r\r\n in the
case of windows line endings, as RawText does not touch the \r, and
ApplyCommand adds "\r\n" if this is the ending of the first line in the
target file. Only always adding \n should be ok, since \r\n would be the
result if the file and the patch include windows line endings.
Also add according test.

Previously, the Dfs GC excluded objects from packs by passing a
previously written index to the PackWriter. Reading back a file on
Dfs is slow. Instead, allow the PackWriter to expose the objects
included in a pack and forward that to invocations of excludeObjects() .

The primary purpose of the filter is to detect an index change that
could possibly lead to a change in what files are visible in the staging
view and decorations. Besides what TreeFilter.ANY_DIFF does for trees in
general, this filter also looks at the assume-valid (CE_VALID) flag to
see whether changes should be ignored or not.

The method is used in only one location (DfsPackFile). Furthermore,
PackIndex already does an explicit computation of the size in
DfsPackFile. Simplify the DfsPackDescription by removing the method
and do the calculation similar to PackIndex.

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

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.

writing of files for any pack extension.

This reverts commit 75eb6a147f.
Applications that want a PathFilter to abort the walk early should be
using PathFilterGroup. When a PathFilterGroup is created with exactly
one path its implementation is the same that 75eb6 tried to perform,
but has been long documented as having the behavior of breaking a
higher level OR filter graph node.

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.

After the current path of the TreeWalk is no longer a prefix of the
PathFilter's path, there can be no more matching entries, but TreeWalk
will happily keep walking the rest of a (potentially very large and
recursive) tree unless StopWalkException is thrown. So, throw
StopWalkException from PathFilter.include() at the earliest
opportunity.

The maxMemory for a DeltaWindow can be optionally disabled when it is
less than or equal to zero. Respect this configuration when enforcing
the limits on object load.
Change-Id: Ic0f4ffcabf82105f8e690bd0eb5e6be485a313b3
Previously, memory limits were enforced at the start of each iteration
of the delta search, based on objects that were currently loaded in
memory. However, new objects added to the window may be expanded in a
future iteration of the search and thus were not accounted for correctly
at the start of the search. To fix this, memory limits are now enforced
before each object is loaded.

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.
