This patch makes JGit parsing of ignore rules containing unmatched '['
bracket compatible to the Git CLI.
Since '[' starts character group, Git tries to parse the ignore rule as
a shell glob pattern and if the character group is not closed, the glob
pattern is invalid and so the ignore rule never matches anything.

Since 4.0 we require Java 7 so there is no longer a need to override the
following methods in FS_POSIX, FS_Win32, FS_Win32_Cygwin
- lastModified()
- setLastModified()
- length()
- isSymlink()
- exists()
- isDirectory()
- isFile()
- isHidden()
Hence implement these methods in FS and remove overrides in subclasses.

As discussed on https://git.eclipse.org/r/53836 it does not make sense
to have two similar utility classes in same package with intersecting
functionality. To not break the API, all methods from FileUtil are
copied to FileUtils, all FileUtil API is made deprecated and redirecting
now to FileUtils. Moved simple methods which are available in Java 7 API
are made package private and can be removed at any point later entirely
(right now they are in use).

An attempt to re-implement not well documented Git CLI behavior for
patterns with backslashes.
It looks like Git silently ignores all \ characters in ignore rules, if
they are NOT covered by 3 cases described in [1]:
{quote}
1) ... Put a backslash ("\") in front of the first hash for patterns
that begin with a hash.
...
2) Trailing spaces are ignored unless they are quoted with backslash
("\").
...
3) Put a backslash ("\") in front of the first "!" for patterns that
begin with a literal "!", for example, "\!important!.txt".
{quote}
Undocumented also is the fact that backslash itself can be escaped by
backslash.
So \h\e\l\l\o\.t\x\t rule matches hello.txt and a\\\\b a\b in Git CLI.
Additionally, the glob parser [2] knows special meaning of backslash:
{quote}
One can remove the special meaning of '?', '*' and '[' by preceding
them by a backslash, or, in case this is part of a shell command
line, enclosing them in quotes. Between brackets these characters
stand for themselves. Thus, "[[?*\]" matches the four characters
'[', '?', '*' and '\'.

The current way of processing submodules results in no hunk header and
includes the contents of the hunk as part of the headers. To fix this, we
can't just have our writeGitLinkDiffText output the hunk header. We have
to change the flow so that the raw text gets parsed as a diff. The easiest
way to do this is to fake the RawText in the FormatResult when we have a
GITLINK.
It should be noted that it seems possible for there to be a difference
between a GITLINK and a non-GITLINK, but I don't think this can happen in
practice, so I don't think we need to worry too much about it.
This patch also fixes up the test for GitLink headers, as the test was
for the old behavior. My setup has 3 other failing tests which may or
may not be the result of environmental changes. However, the same tests
fail without this commit, so I do not believe they are related.

If a client mistakenly tries to send a tag object as a shallow line
JGit blindly assumes this is a commit and tries to parse the tag
buffer using the commit parser. This can cause an obtuse error like:
InvalidObjectIdException: Invalid id: t c0ff331234...
The "t" comes from the "object c0ff331234..." line of the tag tring
to be parsed as though it where the "tree" line of a commit.
Run any client supplied shallow lines through the RevWalk to lookup
the object types. Fail fast with a protocol exception if any of them
are non-commit.
Skip objects not known to this repository. This matches behavior
with git-core's upload-pack, which sliently skips over any shallow
line object named by the client but not known by the server.

This change is according to the behavior of upstream git, which

If no refs match the input list and we are writing to a batch,
the returned new commit from write() will match the current commit.
Adding a command to the batch for this case is harmless as it will
succeed, but it's more straightforward to just skip adding a command
in this case.
Add tests or the combination of saving matching refs and saving to a
batch.

It was reported in [1] that 197e3393a5 led
to a performance regression in a BFG benchmark. Analysis showed that
this is caused by the exists() method in FS_POSIX, now overriding the
default implementation in FS. The default implementation of FS.exists()
uses java.io.File.exists(), while the new implementation in FS_POSIX
uses java.nio.file.Files.exists() - by simply removing the override in
FS_POSIX, performance was restored.
Profiling showed that java.nio.file.Files.exists() is substantially
slower than java.io.File.exists(), to the point where the exists() call
doubles the average cost of a call to
ObjectDirectory.insertUnpackedObject() - which the BFG uses a lot,
because it's rewriting history. Average times measured on Ubuntu were:
java.io.File.exists() - 4 microseconds
java.nio.file.Files.exists() - 60 microseconds
The loose object exists test should be using java.io.File and not FS.
ObjectDirectory uses FS.resolve() to traverse symlinks to objects but
then once inside objects all 256 sharded directories should be real
directories, and the object files should be real files, not dangling
symlinks. java.io.File.exists() is sufficient here, and faster.
Change ObjectDirectory to use File.exists() once its computed the File
handle.
This does mean JGit cannot run ObjectDirectory code on an abstract
virtual filesystem plugged into NIO2. If you really want to run JGit on
an esoteric non-standard filesystem like "in memory" you should look at
the DFS storage backend, which has fewer abstraction points to deal
with. Or write your own from scratch.

On a local filesystem the packed-refs file will be orphaned if it is
replaced by another client while the current client is reading the old
one. However, since NFS servers do not keep track of open files, instead
of orphaning the old packed-refs file, such a replacement will cause the
old file to be garbage collected instead. A stale file handle exception
will be raised on NFS servers if the file is garbage collected (deleted)
on the server while it is being read. Since we no longer have access to
the old file in these cases, the previous code would just fail. However,
in these cases, reopening the file and rereading it will succeed (since
it will reopen the new replacement file). So retrying the read is a
viable strategy to deal with stale file handles on the packed-refs file,
implement such a strategy.
Since it is possible that the packed-refs file could be replaced again
while rereading it (multiple consecutive updates can easily occur with
ref deletions), loop on stale file handle exceptions, up to 5 extra
times, trying to read the packed-refs file again, until we either read
the new file, or find that the file no longer exists. The limit of 5 is
arbitrary, and provides a safe upper bounds to prevent infinite loops
consuming resources in a potential unforeseen persistent error
condition.

Add a public API to the FileUtils to determine if an IOException is a
stale NFS file handle exception. This will make it easier to detect
such errors, and interpret them consistently throughout the codebase.
This new API is a bit more lenient in its detection than the previous
detection, and should be able to detect some errors which previously
were not identified as stale file handle exceptions because they had the
word NFS in the error message. Adjust the packfile handling code to use
this new API for detection.
