After packaging references, the folders containing these references are
not deleted. In a busy repository, this causes operations to slow down
as traversing the references tree becomes longer.
Delete empty reference folders after the loose references have been
packed.
To avoid deleting a folder that was just created by another concurrent
operation, only delete folders that were not modified in the last 30
seconds.

When creating a new PackFile instance it is specified whether this pack
has an associated bitmap index file or not. This information is cached
and the public method getBitmapIndex() will always assume a bitmap index
file must exist if the cached data tells so. But it may happen that the
packfiles are repacked during a gc in a different process causing the
packfile, bitmap-index and index file to be deleted. Since JGit still
has an open FileHandle on the packfile this file is not really deleted
and can still be accessed. But index and bitmap index file are deleted.
Fix getBitmapIndex() to invalidate the cached packfile instance if such
a situation occurs.
This problem showed up when a gerrit server was serving repositories
which where garbage collected with native git regularly. Fetch and
clone commands for certain repositories failed permanently after a
native git gc had deleted old bitmap index files.

When a command invoked from readPipe fails to launch (i.e. the exec call
fails due to a missing command executable), Process.start() throws,
which gets caught by the generic IOException handler, resulting in a
null return. This change detects this case and rethrows a
CommandFailedException instead.
Additionally, this change uses /bin/sh instead of bash for its posix
command failure test, to accomodate building in environments where bash
is unavailable.

Commit db77610 ensured that all refs/tags commits are added to the
primary GC pack. It did that by adding all of the refs/tags commits
to the primary GC pack PackWriter's "interesting" object set.
Unfortunately, all commit objects in the "interesting" set are
selected as commits for which bitmap indices will be built. In a
repository like chromium with lots of tags, this changed the number of
bitmaps created from <700 to >10000. That puts huge memory pressure on
the GC task.
This change restores the original behavior of ignoring tags when
selecting commits for bitmaps.
In the "uninteresting" set, commits for refs/heads and refs/tags for
unannotated tags can not be differentiated. We instead identify
refs/tags commits by passing their ObjectIds as a new "noBitmaps"
parameter to the PackWriter.preparePack() methods.
PackWriterBitmapPreparer.setupTipCommitBitmaps() can then use that
"noBitmaps" parameter to exclude those commits.

DirCacheCheckout is generating names for temporary files. It was not checking
the length of this filenames. It may happen that a generated filename is
longer than 255 chars which causes problems on certain platforms. Make sure
that filenames for temporary files do not exceed 255 chars.

Delete the condition to check whether the garbage pack creation time
is older than the last GC operation, because it's not possible to
find the last GC operation time when there is no GC pack.
Add additional tests to make sure the contents of the expired garbage
packs are considered during the GC operation and any actively
referenced objects from the garbage packs are copied successfully
into the GC pack before deleting the garbage pack.

Android wants them to work, and we're only interested in them for bare
repos, so add them just for that.
Make sure to use symlinks instead of just using the copyfile
implementation. Some scripts look up where they're actually located in
order to find related files, so they need the link back to their
project.

This is necessary for deploying submodules on android.googlesource.com.
* Allow an empty base URL. This is useful if the 'fetch' field is "."
and all names are relative to some host root.
* The URLs in the resulting superproject are relative to the
superproject's URL. Add RepoCommand#setDestinationURI to
set this. If unset, the existing behavior is maintained.
* Add two tests for the Android and Gerrit case, checking the URL
format in .gitmodules; the tests use a custom RemoteReader which is
representative of the use of this class in Gerrit's Supermanifest
plugin.

In the repo manifest documentation [1] the fetch attribute is marked
as "#REQUIRED".
If the fetch attribute is not specified, this would previously result in
NullPointerException. Throw a SAXException instead.

The version string "4.7.0.201704031717-r" is 20 characters, however
the strings used during development are shorter:

- When running in Eclipse, "unknown" is used; 7 characters

DiffAlgorithms can return different edit locations for inserts or
deletes, if they can be "shifted" up or down repeating blocks of
lines. This causes the 3-way merge to apply both edits, resulting in
incorrectly removing or duplicating lines.
Augment an existing "tidy-up" stage in DiffAlgorithm to move all
shiftable edits (not just the last INSERT edit) to a consistent
location, and add test cases for previously incorrect merges.
