After cloning a repo with a submodule, non-recursively, JGit would
encounter in its TreeWalk in IndexDiff:
* first, a missing gitlink (in index & HEAD, not in working tree)
* second, the untracked folder (not in index and head, in working tree)
As a result, it would report the submodule as missing. Canonical git
reports a clean workspace.
The root cause of this is that the path of a gitlink "x" did
not compare equal to the path of a tree "x" in JGit.
Correct Paths.compare() to account for that. If two paths are otherwise
equal, then let gitlinks match both trees and files. Matching trees
solves the bug. Matching files is necessary to handle the case where
the gitlink directory was replaced by a file; see the new test case
IndexDiffSubmoduleTest.testSubmoduleReplacedByFile(). Comparisons of
unequal paths are left untouched, so the sort order is unchanged.
After the fix, another bug(?) in WorkingTreeIterator became apparent:
with core.dirNoGitLinks = true, it was no longer possible to overwrite
a gitlink in the index. This is now fixed in WorkingTreeIterator.
Add new test cases for the bug itself and for some related cases
(submodule directory deleted or replaced by a file) in
IndexDiffSubmoduleTest. Add a test for missing files in IndexDiffTest,
and adapt the PathsTest to test matching gitlinks.

when multiple match options are given in git describe the result must
not depend on the order of the match options. JGit wrongly picked the
first match using the match options in the order they were defined. Fix
this by concatenating the streams of matching tags for all match options
and then choosing the first match on the concatenated stream sorted in
tie break order.

This partially reverts commit a551b646: revert the changes in
RawParseUtils.lineMap(). Forcing all blobs containing a NUL byte
as a single line causes blame to produce useless results as soon
as it hits any version containing a NUL byte.
Doing binary detection at this level also has the problem that the
user cannot control it. Not by setting the text attribute nor in any
other way.
This came up in bug 541036, where a Java source inadvertently
contained NUL bytes in strings. Even fixing this by using escapes
"\000" will not fix JGit's blame for this file because the past
versions will still contain the NUL byte.
Native git can blame that file from bug 541036 fine.
Added new tests verifying that blaming a text file containing a NUL
byte produces sensible results.

Add tests for password and keyboard-interactive authentication.
Implement password authentication; the default provided by sshd
is non-interactive, which is not useful for JGit.
Make sure the CredentialsProvider gets reset on successive password
retrieval attempts. Otherwise it might always return the same non-
accepted password from a secure storage. (That one was discovered
by actually trying this via EGit; the JGit tests don't catch this.)
Change the default order of authentication mechanisms to prefer
password over keyboard-interactive. This is a mitigation for upstream

By default sshd will use its default built-in list, which matches
the one of openssh (as far as the algorithms exist in sshd at all).
But it doesn't handle HostKeyAlgorithms from the ssh config at all.
Implement this as in openssh, including the '+' and '-' modifiers
and reordering the default if there are known host keys for a
server already.
Add tests for the reordering.
Also use a more robust reader for the known hosts file. The default

Tests that it works with unknown authentications in the list, and
fails if there are no common authentications between server and
client. The latter also tests that the ssh config setting is taken
into account at all.
And promptly the JGit sshd client didn't. Add a fix for this. It's
a tiny bit hacky: Apache MINA looks up a custom property set on a
hierarchy of "PropertyResolver"s starting with the session. On the
session itself this property can never be set since it's read
already in the session constructor before anyone had any chance
to set it. The next element in the resolver hierarchy is the sshd
SshClient, and so we set that property there. Since we use one
SshClient and one ClientSession per JGit SshdSession, this is OK.

Add a new ssh client implementation based on Apach MINA sshd 2.0.0.
This implementation uses JGit's own config file parser and host entry
resolver. Code inspection of the Apache MINA implementation revealed
a few bugs or idiosyncrasies that immediately would re-introduce bugs
already fixed in the past in JGit.
Apache MINA sshd is not without quirks either, and I had to configure
and override more than I had expected. But at least it was all doable
in clean ways.
Apache MINA boasts support for Bouncy Castle, so in theory this should
open the way to using more ssh key algorithms, such as ed25519.
The implementation is in a separate bundle and is still not used in
the core org.eclipse.jgit bundle. The tests re-use the ssh tests from
the core test bundle.

Add support for git-receive-pack to the ssh git server and add two
new tests for pushing.
This actually uncovered an undocumented requirement in TransportSftp:
the FTP rename operation assumes POSIX semantics, i.e., that the
target is removed. This works as written only for servers that
support and advertise the "posix-rename@openssh.com" FTP extension.
Our little Apache MINA server does not advertise this extension.
Fix the FtpChannel implementation for Jsch to handle this case in a
meaningful way so that it can pass the new "push over sftp" test.
Add more tests to test the behavior of server host key checking.
Also refactor the tests generally to separate better the test
framework from the actual tests.

Suppose that a repository has the following commit graph:
B C
\ /
A
and it was cloned with --shallow-exclude=A. DepthGenerator does not mark
C as shallow, causing an invalid repository to be produced on the
client, because A is not sent. (A similar issue occurs when
--shallow-since is used to exclude A but neither B nor C.)
This happens whenever an excluded commit has more than one child that is
to be sent to the client. Fix DepthGenerator to handle this case
correctly.
While we're editing DepthWalk.Commit, fix the documentation of
DepthWalk.Commit#isBoundary.

Move the bulk of the basic parsing and host entry handling into a
new class OpenSshConfigFile that has no dependencies on any concrete
ssh implementation. Make the existing OpenSshConfig use the new
parser.
Introduce a new class SshConstants collecting all the various ssh-
related string literals. Also use TreeMaps with a case-insensitive
key comparator instead of converting keys to uppercase. Add a test
to verify that keys are matched case-insensitively.
Most of the parsing code was simply moved, except that the new
parser supports looking up entries given host name, port, and user
name, and can thus handle more %-substitutions correctly. This
feature is not yet used and cannot be used with JSch since JSch
only has a ConfigRepository.getConfig(String) interface.
The split is still worth the trouble as it opens the way to using
another ssh client altogether. Apache MINA sshd, for instance,
resolves host entries giving host name, port, and user name.
(Apache MINA has a built-in ssh config handling, but that has
problems, too: its pattern matching is case-insensitive, and its
merging of host entries if several match is not the same as in
OpenSsh. But with this refactoring, it will be possible to plug in
OpenSshConfigFile into an Apache MINA sshd client without dragging
along JSch.)
One test case that doesn't make sense anymore has been removed. It
tested that repeatedly querying for a host entry returned the same
object. That is no longer true since the caching has been moved to
a deeper level.

In C Git, when a client fetches with "git fetch --shallow-since=<date>
origin <ref>", and all commits reachable from <ref> are older than
<date>, the server dies with a message "no commits selected for shallow
requests". That is, (1) the --shallow-since filter applies to the commit
pointed to by the ref itself, and (2) there is a check that at least one
commit is not filtered out. (The pack-protocol.txt documentation does
not describe this, but the C implementation does this.)
The implementation in commit 1bb430dc21 ("UploadPack: support
deepen-since in protocol v2", 2018-09-27) does neither (1) nor (2), so
do both of these.

UploadPack.getPeerUserAgent() doesn't produce the expected results for
protocol v2 requests. In v2, the agent reported in the request (in an
"agent=" line) is not in the clientCapabilities but in a field on its
own. This makes getPeerUserAgent default to the transport user agent.
Making "agent" a shared property between protocol v0/v1 and v2 fixes the
problem, simplifies the function and harmonizes the implementation
between protocol versions.
In a follow up commit the "agent" will be identified on parsing time,
instead of taking it from the client capabilities.
