When either --tags or a tag ref is explicitly specified on fetch, C Git
updates existing local tags if they are different.
Before this change, JGit returned REJECTED in such a case. Now it
updates it and returns FORCED.
Example:
% mkdir a
% cd a
% git init -q
% touch test.txt
% git add test.txt
% git commit -q -m 'Initial'
% git tag v1
% cd ..
% git clone -q a b
% cd a
% echo Test > test.txt
% git commit -q -a -m 'Second'
% git tag -f v1
Updated tag 'v1' (was bc85c08)
% cd ../b
% git fetch --tags
- [tag update] v1 -> v1

This corresponds to what C Git does, quoting from the fetch man page:
This is done by first fetching from the remote using the given
<refspec>s, and if the repository has objects that are pointed by
remote tags that it does not yet have, then fetch those missing tags.
Before, JGit would also fetch tags that exist locally but point to a
different object, resulting in REJECTED results for these.
Also add some test cases to cover more cases.

Depending on the order in which items are traversed for RECURSIVE, an
empty directory may come first before detecting that there is a file and
aborting.
This fixes it by traversing files first.

If the HEAD is not present in a repository, then there is a
NullPointerException thrown in the delete code. Since this only
exists to verify if the deletion is not the HEAD reference, then
skip this check if the HEAD cannot be found.

When ArchiveCommand is invoked directly on the command line, these
warnings to stderr
warning: mode of path/to/some/submodule ignored
are a useful hint, but in the more usual case where an archive is
being served by a server, the intended audience for that message
cannot see stderr.
Later it might be useful to accept a callback to return these warnings
out of band.

The only caller exits immediately after calling execute() so this
shouldn't make a difference, but it's good practice and should make it
easier to expose the functionality in a public API later.

This reverts commit 7aa54967a2.
The unit test dependend upon the specific order of names that
listFiles() returned members in. The order is completely undefined
and may differ even on different versions of Linux based systems.
A proper unit test for this code would have considered both cases,
where the deletion function was able to remove an empty subdirectory,
or fail to remove a subdirectory because a file was still present
within. This is not such a test.

Adds a new method getConflictingStageStates() which returns a
Map<String, StageState> (path to stage state). StageState is an enum for
all possible stage combinations (BOTH_DELETED, ADDED_BY_US, ...).
This can be used to implement the conflict text for unmerged paths in
output of "git status" or in EGit for decorations/hints.

Commit 3344b93c erroneously exported the package org.eclipse.jgit.lib
from the org.eclipse.jgit.test bundle which made this a split package
since the bundle org.eclipse.jgit exports the same package.
Split packages are evil in general and most probably caused the build
cycle errors observed recently when importing the jgit projects in
Eclipse [1].

Instead of counting objects processed, count number of bytes added
into the window. This should rescale the progress meter so that 30%
complete means 30% of the total uncompressed content size has been
inflated and fed into the window.
In theory the progress meter should be more accurate about its
percentage complete/remaining fraction than with objects. When
counting objects small objects move the progress meter more rapidly
than large objects, but demand a smaller amount of work than large
objects being compressed.

Instead of assuming all objects cost the same amount of time to
delta compress, aggregate the byte size of objects in the list
and partition threads with roughly equal total bytes.
Before splitting the list select the N largest paths and assign
each one to its own thread. This allows threads to get through the
worst cases in parallel before attempting smaller paths that are
more likely to be splittable.
By running the largest path buckets first on each thread the likely
slowest part of compression is done early, while progress is still
reporting a low percentage. This gives users a better impression of
how fast the phase will run. On very complex inputs the slow part
is more likely to happen first, making a user realize its time to
go grab lunch, or even run it overnight.
If the worst sections are earlier, memory overruns may show up
earlier, giving the user a chance to correct the configuration and
try again before wasting large amounts of time. It also makes it
less likely the delta compression phase reaches 92% in 30 minutes
and then crawls for 10 hours through the remaining 8%.

By excluding objects the compactor can avoid storing objects that
are already well packed in the base GC packs, or any other pack
not being replaced by the current compaction operation.
For deltas the base object is still included even if the base exists
in another exclusion set. This favors keeping deltas for recent
history, to support faster fetch operations for clients.

Use recursive merge as the default strategy since it can successfully
merge more cases than the resolve strategy can. This is also the default
in native Git.

Previously, the code assumed all commits in the old pack would also
be present in the new pack. This assumption caused an
ArrayIndexOutOfBoundsException during remapping of ids. Fix the
iterator to only return entries that may be remapped. Furthermore,
update getBitmap() to return null if commit does not exist in the
new pack.

* changes:
Always attempt delta compression when reuseDeltas is false
Avoid TemporaryBuffer.Heap on very small deltas
Correct distribution of allowed delta size along chain length
Split remaining delta work on path boundaries
Replace DeltaWindow array with circularly linked list
Micro-optimize copy instructions in DeltaEncoder
Micro-optimize DeltaWindow primary loop
Micro-optimize DeltaWindow maxMemory test to be != 0
Mark DeltaWindowEntry methods final
If reuseObjects=true but reuseDeltas=false the caller wants attempt
a delta for every object in the input list. Test for reuseDeltas
to ensure every object passes through the searchInWindow() method.
If no delta is possible for an object and it will be stored whole
(non-delta format), PackWriter may still reuse its content from any
source pack. This avoids an inflate()-deflate() cycle to recompress
the object contents.

TemporaryBuffer is great when the output size is not known, but must
be bound by a relatively large upper limit that fits in memory, e.g.
64 KiB or 20 MiB. The buffer gracefully supports growing storage by
allocating 8 KiB blocks and storing them in an ArrayList.
In a Git repository many deltas are less than 8 KiB. Typical tree
objects are well below this threshold, and their deltas must be
encoded even smaller.
For these much smaller cases avoid the 8 KiB minimum allocation used
by TemporaryBuffer. Instead allocate a very small OutputStream
writing to an array that is sized at the limit.
