DirCacheCheckout: load WorkingTreeOptions only once
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.

I649db9ae679ec2606cf7c530b040f8b6b93eb81a added a default implementation

Add the ability to override parents on RevCommit.
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.

[tests] Stabilize the HTTP server's request log
The TestRequestLog added log entries only after a request had been
handled. But the response is already sent at that point, so the
following sequence was possible:
client sends request A
server thread T1 handles request A and sends back response
client receives response
client sends request B
server thread T2 handles request B (and sends back response)
server thread T2 logs B
server thread T1 logs A
Fix this by logging events before handling a request, and then filling
in the response data after the request has been handled. This should
avoid such inversions, at least for tests using a single single-threaded
client. With multiple concurrent or multi-threaded clients, all bets
about the log order would be off anyway.

NameConflictTreeWalk: respect git order on multi-tree iteration
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.

Do not create reflog for remote tracking branches during clone
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.

UploadPack: do not check reachability of visible SHA1s

The check is also performed when the SHA1 corresponds to
one of the tips of the advertised refs which is a waste of

UserAuthPublicKey instance. Only that one is null by default, and then
Apache MINA sshd just uses the key type as signature type. Which for
RSA keys from an agent is the "ssh-rsa" signature, i.e., the deprecated
