Dynamically detect if Windows supports symbolic links
To get symlink support you typically need to run as administrator.

The change includes comparing symbolic links between disk and index,
adding symbolic links to the index, creating/modifying links on
checkout. The behavior is controlled by the core.symlinks setting, just
as C Git does. When a new repository is created core.symlinks will be
set depending on the capabilities of the operating system and Java
runtime.
If core.symlinks is set to true, the assumption is that symlinks are
supported, which may result in runtime errors if this turns out not to
be the case.
Measuring the cost of jgit status on a repository with ~70000 files,
of which ~30000 are tracked reveals a penalty of about 10% for using
the Java7 (really NIO2) support module.

Fix MissingObjectException race in ObjectDirectory
Johannes Carlsson identified a race condition[1] that can lead to
spurious MissingObjectExceptions at read time. If two threads are
active inside of ObjectDirectory looking for a packed object and the
packList is currently the empty NO_PACKS list, thread A will find
no object and eventually consider tryAgain1(). If thread A is put
to sleep and this point and thread B also does not find the object,
loads the packs, when thread A wakes up its tryAgain1 would return
false and the thread never considers the packs.
Rework the internal API of ObjectDirectory to keep a handle on the
exact PackList that was iterated by thread A, allowing it to always
retry walking through the packs if the new PackList is different.
This had some ripple effect into the CachedObjectDirectory and
the shared FileObjectDatabase interface. The new code should be
slightly easier to follow, especially from the perspective of the
CachedObjectDirectory trying to minimize the number of open system
calls it makes to files matching "$GIT_DIR/objects/??/?x{38}".

In certain cases a JGit server updating an existing shallow client
selected a common ancestor that was behind the shallow edge of
the client. This allowed the server to assume the client had some
objects it did not have and allowed creation of pack deltas the
client could never inflate.
Any commit the client has advertised as shallow must be treated
by UploadPack server as though it has no parents. With no parents
the walker cannot visit graph history the client does not have,
and PackWriter cannot consider delta base candidates the client
is lacking.

When encountering a submodule entry, "jgit archive" tries to write its
content verbatim as an entry to the archive, which fails with a
JGitInternalException wrapping a MissingObjectException because the
submodule repository commits are typically not part of the
superproject.
When a subproject is available (for example because it has been
checked out as a subdirectory of a superproject worktree), it would be
nice to recurse into it and make one archive recording the state of
the entire project. Unfortunately sometimes the subproject is not
available or it can be hard to find (e.g., it can be on another
server). Even when some subprojects are available, "jgit archive"
should not produce different output for the same tree depending on
which subprojects it has easy access to, so there is no obvious good
default behavior that recurses without relying on access to all
subprojects.
Instead, replace each submodule entry with a placeholder empty
directory. "git archive" does the same.

Entries for directories are optional and mostly wasted space in most
archive formats (except as a place to hang ownership and filesystem
permissions), but "git archive" includes them. Follow suit.
This will make it easier in a later change to include empty
directories as placeholders for missing submodules.

Revert "Fix for core.autocrlf=input resulting in modified file..."
This reverts commit 1def0a1257.
We found this fix uncovers problems with unsmudged DirCacheEntry's. This
surfaced because egit's ui test CreatePatchActionTest failed since jgit
computes a wrong status. JGit doesn't detect modified content in now
unsmudged entries. Hence revert this change until these problems are
fixed.

archive: Prepend a specified prefix to all entry filenames
Common practice when distributing tarballs is to prefix all entries
with a single directory name so when the tarball is extracted it all
falls neatly into a single directory. Add a setPrefix() method to
ArchiveCommand to support this.

Canonicalize worktree path in BaseRepositoryBuilder if set via config
This is the case for submodules in .git/modules, which typically have a

This came up while testing the proposed buck build for jgit. With buck
we can introduce smaller modules to allow for more concurrency during
build and to better control inner structure of jgit. Trying to put the
porcelain API into a different module than lower level implementation
classes failed since RebaseTodoLine used a porcelain API exception
causing a dependency cycle on the proposed modules. Using an exception
defined on the same abstraction level fixes this problem.
