The value of -1 is the default value used by the underlying http
transports provided by the jre. On some versions an attempt to
set the timeout explicitly to -1 triggers a check condition,
disallowing negative numbers.

None of these should have been exposed to base classes. The majority
of them are private implementation details that are not required by a
subclass in order to interact with the base protocol definition. The
few that are needed should be visible as accessor methods, so the
internals can be modified without breaking the public JGit API.

This flag was added to provide an unsafe operation on the local
repository because the storage.dht code was too damn slow to provide
proper safe Git behavior all of the time. Now that stoarge.dht has
been removed from the repository, also delete this unsafe flag to
prevent applications from misusing the JGit library and permitting
users to potentially damage their local repository with bad data
received from an untrusted peer.

This experiment proved to be not very useful. I had originally
planned to use this on top of Google Bigtable, Apache HBase or
Apache Cassandra. Unfortunately the schema is very complex and
does not perform well. The storage.dfs package has much better
performance and has been in production at Google for many months
now, proving it is a viable storage backend for Git.

As there are no users of the storage.dht schema, either at Google or
any other company, nor any valid open source implementations of the
storage system, drop the entire package and API from the JGit project.
There is no point in trying to maintain code that is simply not used.

When a file is not in the index and neither contents nor mode differ
between "head" and "merge", the index state should be kept. If they
differ, a checkout conflict should occur. This is described in Git's
git-read-tree.txt.

JGit used to replace the index state with "merge" in both of the above
cases.

A confusing effect of this was that when one removed a file and then did
a rebase, the file silently reappeared again.

The changes to dir/file conflict handling are a consequence of this
change, as the index handling change made tests in DirCacheCheckoutTest
break. I compared these cases to C Git and the new behavior there also
matches what C Git does.

The transformation is the same as AutoCRLFOutputStream does, but
the direction is reversed. The tests are reused, but the implementation
derives somewhat from the EolCanonicalizingInputStream.

This stream will be used to compare blobs with LF line endings with
worktree data that has CRLF line endings.

In order to parse user specified strings containing date and time info
a thread-safe parser is implemented. This is needed for example to
interpret configuration parameters (e.g. gc.pruneexpire where need to
parse strings like "2 weeks ago"). The parser is thread-safe by caching
SimpleDateFormat instances in a ThreadLocal cache.

Native git has a parser called approxidate which is able to interpret a
huge number of formats ("1 year ago", "tea time", ...). Ideally JGit
should be able to parse the same strings as native git but for now this
parser understands the following subset:

"now"
"yesterday"
"(x) years|months|weeks|days|hours|minutes|seconds ago"
"yyyy-MM-dd HH:mm:ss Z" (ISO)
"EEE, dd MMM yyyy HH:mm:ss Z" (RFC)
"yyyy-MM-dd"
"yyyy.MM.dd"
"MM/dd/yyyy"
"dd.MM.yyyy"
"EEE MMM dd HH:mm:ss yyyy Z" (DEFAULT)
"EEE MMM dd HH:mm:ss yyyy" (LOCAL)

JGit was not able to lookup refs which had the name of files which exist
in the .git folder. When JGit was looking up a ref named X it has a
fixed set of directories where it searched for files named X
(ignore packed refs for now). First directory to search for is .git. In
case of the ref named 'config' it searched there for this file, found it
(it's the .git/config file with the repo configuration in it), parsed
it, found it is an invalid ref and stopped searching. It never looked
for a file .git/refs/heads/config.

I changed JGit in a way that when it finds a file in GIT_DIR which
corresponds to a ref name and if this file doesn't contain a valid ref
then it will ignore the InvalidObjectIdException and continue searching.

On conflicts in rebase or cherry-pick, the conflict markers were like
this:

    <<<<<<< OURS
    a
    =======
    b
    >>>>>>> THEIRS

This is technically correct, but it could be better.

It's especially confusing during a rebase, where the meaning of
OURS/THEIRS is not obvious. The intuition is that "ours" is the commits
that "I" did before the rebase, but it's the other way around because of
the way rebase works. See various bug reports and stackoverflow
discussions.

With this change, in the case of a cherry-pick while on master, the
markers will be like this:

    <<<<<<< master
    a
    =======
    b
    >>>>>>> bad1dea Message of the commit I'm cherry-picking

In the case of a "git rebase master":

    <<<<<<< Upstream, based on master
    a
    =======
    b
    >>>>>>> b161dea Message of a commit I'm rebasing

It's not "master" because that would only be correct for the first
cherry-pick during a rebase, after that, it's master + already
cherry-picked commits.

And in the case of a "git pull --rebase":

    <<<<<<< Upstream, based on branch 'master' of git@example.org:repo
    a
    =======
    b
    >>>>>>> b161dea Message of a commit I'm rebasing

If an object is in a pack file already, delta compression will not
attempt to re-compress it. This assumes that the previous
packing already performed the optimal compression attempt, however,
the subclasses of StoredObjectRepresentation may use other heuristics
to determine if the stored format is optimal.

JGit allows to create commits which have duplicate parents: e.g. a
commit X has first parent Y and second parent Y. Such commits are not
handled correctly by PlotCommit leading to wrong display of the history
in EGit. In such cases there is a never ending passing line drawn beside
all commits younger than the commit with duplicate parents. This commit
fixes this by explicitly checking for duplicate parents.

In a different commit we should fix JGit not to create commits with
duplicate parents. I think native git also doesn't allow such commits,
although history display in native git (gitk, git log --graph) is not
damaged by such commits.
