Don't convert a lot of ObjectId to String stored in generic
java.util.HashSet. This is a very expensive way to store objects.
Instead rely on "this" from the FsckPackParser to lookup information
about the objects in this pack file, which lets the verify code avoid
sorting the object list.
Use ObjectIdOwnerMap, which is the most efficient format JGit has
for storing lots of objects.

A few static imports from PackExt and slightly shorter variable names

The simpler algorithm is to load all branch tips into an ObjectWalk

Move the connectivity check into its own helper method. This moves it

Revert the following save actions which were introduced in c0ad77d8:
- always use braces around blocks
- remove unused imports
Other than I expected save actions are run globally on edited files -
and not only on edited code lines only.
Hence revert the save action "Convert control statement bodies to
blocks" which would affect a large number of code lines not affected by
the change editing some small part of a class. This would generate a
large number of changes which may lead to many unnecessary conflicts.
Total number of affected lines across jgit would be around 10k lines.
Also revert "Remove unused imports" since it erroneously removes imports
of some annotations needed by pgm classes using args4j.

Some repositories can have a policy that do not accept certain blobs. To
check if the incoming pack file contains such blobs, ObjectChecker can
be used. However, this ObjectChecker is not called by PackParser if the
blob is stored as a whole. This is because the object can be so large
that it doesn't fit in memory.
This change introduces BlobObjectChecker. This interface takes chunks of
a blob instead of the entire object. ObjectChecker can optionally return
a BlobObjectChecker. This won't change existing ObjectChecker
implementation; existing implementation continues to receive deltified
blob objects only.

Path pattern matching for attribute rules is different than matching
for excluded files.
The first difference concerns patterns without slashes. For
gitattributes those must match on the last component only, not on
any earlier segment. This is true also for directory-only patterns.
The second difference concerns directory-only patterns. Those also
must not match on a prefix or segment except the last one. They do
not apply recursively to all files beneath.
And third, matches only on a prefix must match for gitattributes
only if the last matcher was "/**".
Add a new parameter for such path matching to IMatcher.matches() and
pass it through as appropriate (false for gitignore, true for
gitattributes). As far as gitignore is concerned, there is no change.
New tests have been added, and some existing attribute matching tests
have been fixed since they operated on wrong assumptions.

These tests verify that JGit matches the same as C git, for
both attribute matching (.gitattributes) and file exclusion matching
(.gitignore). These tests work by setting up a test repository and
test rules, and then determine excluded files or attributes both with
JGit and with the native C git, and then compare the results.
For .gitignore tests, we run
git ls-files --ignored --exclude-standard -o
and for attribute tests we use
git check-attr --stdin --all
and pass the list of all files in the repository via stdin.

Reading RefSpecs from a Config can be seen as another typed value
conversion, so add a getter to Config and to TypedConfigGetter. Use

custom TypedConfigGetter.

Make the handling of typed values somewhat configurable by using
a separate converter. The default converter is the same as before;
just the implementations of the getters were moved. They also still
raise IllegalArgumentException on invalid values as before.
The converter can be set globally via Config.setTypedConfigGetter(),
which EGit can use in its core Activator to plug in a variant that
catches the IllegalArgumentException, logs the problem, and then
returns the default value.
In this way the behavior for other users of the JGit library is
unchanged, while EGit can deal gracefully with invalid git configs.

Except for %p and %r and partially %C, we can do token substitutions
as defined by OpenSSH inside the config file parser. %p and %r can
be replaced only if specified in the config; if not, it would be the
caller's responsibility to replace them with values obtained from the
URI to connect to.
Jsch doesn't know about token substitutions at all. By doing the
replacements as good as we can in the config file parser, we can
make Jsch support most of these tokens.
%i is not handled at all as Java has no concept of a "user ID".
Includes unit tests.

Ensure the Jsch instance used knows about ~/.ssh/config. This
enables Jsch to honor more user configurations (see
com.jcraft.jsch.Session.applyConfig()), in particular also the
UserKnownHostsFile configuration, or additional identities given
via multiple IdentityFile entries.
Turn JGit's OpenSshConfig into a full parser that can be a
Jsch-compliant ConfigRepository. This avoids a few bugs
in Jsch's OpenSSHConfig and keeps the JGit-facing interface
unchanged. At the same time we can supply a JGit OpenSshConfig
instance as a ConfigRepository to Jsch. And since they'll both
work from the same object, we can also be sure that the parsing
behavior is identical.
The parser does not handle the "Match" and "Include" keys, and it
doesn't do %-token substitutions (yet).
Note that Jsch doesn't handle multi-valued UserKnownHostFile
entries as known by modern OpenSSH.[1]

The addition of "tooManyRedirects" in commit 7ac1bfc ("Do
authentication re-tries on HTTP POST") was an error I didn't
catch after rebasing that change. That message had been renamed
in the earlier commit e17bfc9 ("Add support to follow HTTP
redirects") to "redirectLimitExceeded".
Also make sure we always use the TransportException(URIish, ...)
constructor; it'll prefix the message given with the sanitized URI.
Change messages to remove the explicit mention of that URI inside the
message. Adapt tests that check the expected exception message text.
For the info logging of redirects, remove a potentially present
password component in the URI to avoid leaking it into the log.

There is at least one git server out there (GOGS) that does
not require authentication on the initial GET for
info/refs?service=git-receive-pack but that _does_ require
authentication for the subsequent POST to actually do the push.
This occurs on GOGS with public repositories; for private
repositories it wants authentication up front.
Handle this behavior by adding 401 handling to our POST request.
Note that this is suboptimal; we'll re-send the push data at
least twice if an authentication failure on POST occurs. It
would be much better if the server required authentication
up-front in the GET request.
Added authentication unit tests (using BASIC auth) to the
SmartClientSmartServerTest:
- clone with authentication
- clone with authentication but lacking CredentialsProvider
- clone with authentication and wrong password
- clone with authentication after redirect
- clone with authentication only on POST, but not on GET
Also tested manually in the wild using repositories at try.gogs.io.
That server offers only BASIC auth, so the other paths
(DIGEST, NEGOTIATE, fall back from DIGEST to BASIC) are untested
and I have no way to test them.
* public repository: GET unauthenticated, POST authenticated
Also tested after clearing the credentials and then entering a
wrong password: correctly asks three times during the HTTP
POST for user name and password, then gives up.
* private repository: authentication already on GET; then gets
applied correctly initially to the POST request, which succeeds.
Also fix the authentication to use the credentials for the redirected
URI if redirects had occurred. We must not present the credentials
for the original URI in that case. Consider a malicious redirect A->B:
this would allow server B to harvest the user credentials for server
A. The unit test for authentication after a redirect also tests for
this.

Add an update_index to every reference in a reftable, storing the
exact transaction that last modified the reference. This is necessary
to fix some merge race conditions.
Consider updates at T1, T3 are present in two reftables. Compacting
these will create a table with range [T1,T3]. If T2 arrives during
or after the compaction its impossible for readers to know how to
merge the [T1,T3] table with the T2 table.
With an explicit update_index per reference, MergedReftable is able to
individually sort each reference, merging individual entries at T3
from [T1,T3] ahead of identically named entries appearing in T2.
