Previous code loaded the WorkingTreeOptions afresh for every single
file being checked out. This checked the git config (all three files,
repo, user and system config) for having been modified every time.
These checks can be costly, for instance on Windows, or if one of the
three config files is not on a local disk, or on an otherwise slow
storage.
Improve this by loading the options and thus checking the git config
only once before the checkout.

With core.symlinks=false, symlinks are checked out as plain files.
When such a file is re-added to the index, and the index already
contains a symlink there, add the file as a symlink. Previous code
changed the index entry to a regular file.

String.startsWith() is not a valid test for file path prefixes:
directory "a" is _not_ a prefix of a file "ab", only of "a/b".
Add a proper Paths.isEqualOrPrefix() method and use it in CleanCommand.

This can allow passing a FilteredRevCommit which is the filtered list of
commit graph making it easier for Blame to work on. This can
significantly improve blame performance since blame can skip expensive
RevWalk.
Change-Id: I5dab25301d6aef7df6a0bc25a4c553c730199272
This makes RevCommit extensible to allow having different structure of
child-parent relationship. This change is a pre-requsite for having a
FilteredRevCommit that overrides parents from the RevCommit. That then
provides a cheaper way to walk over a subset of RevCommits instead of
an expensive way that applies filters while walking over selected
commits. Useful with Blame which works on a single file and that can be
made performant, if we know all the commits needed by the Blame
algorithm. So Blame algorithm can avoid walking over finding what
commits to blame on.
This change makes parents field on RevCommit private and exposes it
thrrough overrideable methods such as getParents, getParent at index,
getParentCount and setParents. All other files other than RevCommit are
updating the usages of accessing RevCommits parents.

The NameConflictTreeWalk class is used in 3-way merge for iterating over
entries in 3 different commits. The class provides information about a
current entry and a state of the entry in commits (e.g entry is file,
entry is directory, entry is missing). In rare cases, the tree walker
can mix information about entries with different name.
The problem appears, because git uses unusual sorting order for
files. Example (this is a simplified real-life example):
Commit 1:
* gradle.properties - file
* gradle - directory (with nested files)
* gradle/file - file in gradle directory
Commit 2:
* gradle.properties - file
* no entry with the name gradle
Commit 3:
* gradle.properties - file
* gradle - file
Here the names are ordered like this:
"gradle" file <"gradle.properties" file < "gradle/file" file.
NameConflictTreeWalk iterator already have code for processing
git sorting order, however in the example above the code doesn't
work correctly. Before the fix, NameConflictTreeWalk returns:
#next()
"gradle - directory" | "gradle.properties" | "gradle - file" - which is
wrong. The expected result is
#next()
"gradle - directory | MISSED_FILE | "gradle - file"
#next()
"gradle.properties"|"gradle.properties"|"gradle.properties"
Ensure that the "matches" field of tree iterators (which contains the
current path) is kept in sync in the case above.

The RootIgnoreNode in a WorkingTreeIterator must _not_ add the rules
from .git/info/exclude or from the file designated by git config
core.excludesFile to the list of rules read from the root .gitignore.
These really must be separate nodes in a hierarchy, otherwise the
precedence rules from [1] are violated and the outcome is not the
same as in C git.

When using JGit on a non-bare repository, the CloneCommand
it previously created local reflogs for all branches including remote
tracking ones, causing the generation of a potentially large
number of files on the local filesystem.
The creation of the remote-tracking branches (refs/remotes/*) during
clone is not an issue for the local filesystem because all of them are
stored in a single packed-refs file. However, the creation of a large
number of ref logs on a local filesystem IS an issue because it
may not be tuned or initialised in term of inodes to contain a very
large number of files.
When a user (or a CI system) performs the CloneCommand against
a potentially large repository (e.g., millions of branches), it is
interested in working or validating a single branch or tag and is
unlikely to work with all the remote-tracking branches.
The eager creation of a reflogs for all the remote-tracking branches is
not just a performance issue but may also compromise the ability to
use JGit for cloning a large repository.
The behaviour implemented in this change is also consistent with the
optimisation done in the C code-base [1].
We differentiate between clone and fetch commands using --branch
<initialBranch> option, that is only available in clone command,
and is set as HEAD per default.

Updating the AmazonS3 class to support AWS Signature version 4 because
version 2 is no longer supported in all AWS regions. The version can be
selected with the new 'aws.api.signature.version' property (defaults to

specify the AWS region via the 'region' property. The 'region' property
must match the region that the 'domain' property resolves to.

NOTE: port back from master branch.
On process exit, it was possible that the filesystem timestamp
resolution measurement left behind .probe files or even a lock file
for the jgit.config.
Ensure the SAVE_RUNNER is shut down when the process exits (via
System.exit() or otherwise). Move lf.lock() into the try-finally
block when saving the config file.
Delete .probe files on JVM shutdown -- they are created in daemon
threads that may terminate abruptly, not executing the "finally"
clause that normally removes these files.
