Hoist ObjectIdSet up to lib as part of the public API and add
the interface to some common types like PackIndex and JGit custom
ObjectId map types. This cleans up wrapper code in a number of
places by allowing direct use of the types as an ObjectIdSet.
Future commits can now rely on ObjectIdSet as a simple read-only
type to check a set of objects from a number of storage options.

If a file (e.g. "A") and a subtree file (e.g. "A/foo.c") both appear
in the DirCache this cache should not be written out as a tree object.
The "A" file and "A" subtree conflict with each other in the same tree
and will fail fsck.
Detect this condition during DirCacheBuilder and DirCacheEditor
finish() so the application can be halted early before it updates a
DirCache that might later write an invalid tree structure.

If a PathEdit tries to store a file where a subtree was, or a subtree
where a file was, replace the entry in the DirCache with the new
name(s). This supports switching between file and tree entry types
using a DirCacheEditor.
Add new unit tests to cover the conditions where these can happen.

Adding a path that already exists but is changing type such as
from symlink to subdirectory requires a NameConflictTreeWalk to
match up the two different entry types that share the same name.
NameConflictTreeWalk needs a bug fix to pop conflicting entries
when PathFilterGroup aborts the walk early so that it does not
allow DirCacheBuilderIterator to copy conflicting entries into
the output cache.

The "--" path option (and all other similar options consuming all
remaining arguments) should be placed at the end of the command line
help.
Currently jgit reset -h shows this:
jgit reset [commit-ish] [path ... ...] [-- path ... ...] [--hard]
[--help (-h)] [--mixed] [--soft]
After the patch the help shows this:

Signal early command termination due '-h' or '--help' option via
TerminatedByHelpException. This allows tests using
CLIGitCommand differentiate between unexpected command parsing errors
and expected command cancellation "on help" (which also allows
validation of expected/unexpected help messages).
Additional side-effect: jgit supports now git style of handling help
option: any unexpected command line options before help are reported as
errors, but after help ignored.

JGit CLI should allow to do this: checkout -- <path>
Currently, even if "a" is a valid path in the git repo, jgit CLI can't
checkout it:
$jgit checkout -- a

The fix also fixes at same time "unnamed" zombie "[VAL ...]" argument

After fix:

When setting timeout on push, BasePackConnection creates a timer, which
will be terminated when push finishes. But, when using
SmartHttpPushConnection, it dropped the first timer created in the
constructor and then created another timer in doPush. If new threads are
created faster than the gc collects then this may stop the service if
it's hitting the max process limit. Hence don't create a new timer if it
already exists.

PathFilter and PathFilterGroup form JGit's implementation of git's
path-limiting feature in commands like log and diff. To save time
when traversing trees, a path specification
foo/bar/baz
tells the tree walker not to traverse unrelated trees like qux/. It
does that by returning false from include when the tree walker is
visiting qux and true when it is visiting foo.
Unfortunately that test was implemented to be slightly over-eager: it
doesn't only return true when asked whether to visit a subtree "foo"
but when asked about a plain file "foo" as well. As a result, diffs
and logs restricted to some-file/non-existing-suffix unexpectedly
match against some-file:

Fix it by checking against the entry's mode.
Gitiles +log has the same bug and benefits from the same fix.
Callers know not to worry about what subtrees are included in the tree
walk because shouldBeRecursive() returns true in this case, so this
behavior change should be safe. This also better matches the behavior
of C git:
$ empty=$(git mktree </dev/null)
$ git diff-tree --abbrev $empty HEAD -- LICENSE/no-such-file
$ git diff-tree --abbrev $empty HEAD -- tools/no-such-file

Expand the existing PathFilterGroup tests to check which paths the
tree entry matches. This expands test coverage by ensuring that
PathFilterGroup's simpler code path to match against a single
PathFilter works correctly.
While at it, move the check on tree entry d/e/f/g.y into two separate
tests: one to check that it doesn't match any of the configured paths,
and another to check that it does not throw StopWalkException to end
the walk early.

Pushing with JGit commandline to e.g. Github failed with "unauthorized"
since HttpUrlConnection calls the configured authenticator implicitly.
The problem is that during a push two requests are sent to the server,
first a GET and then a POST (containing the pack data). The first GET
request sent anonymously is rejected with 401 (unauthorized). When an
Authenticator is installed the java.net classes will use the
Authenticator to ask the user for credentials and retry the request.
But this happens under the hood and JGit level code doesn't see that
this happens.
The next request is the POST but since JGit thinks the first GET request
went through anonymously it doesn't add authentication headers to the
POST request. This POST of course also fails with 401 but since this
request contains a lot of body-data streamed from JGit (the pack file!)
the java.net classes can't simply retry the request with authorization
headers. The whole process fails.
Fix this by using Apache httpclient which doesn't use Authenticator to
retrieve credentials. Instead initialize TransportCommand to use the
default credential provider if no other credentials provider was set
explicitly. org.eclipse.jgit.pgm.Main sets this default for the JGit
command line client.

BasePackPushConnection#readStringLongTimeout() was setting a timeout 10
times bigger than some other timeout or the pack transfer time. This
could lead to negative integer values when we hit an arithmetic
overflow. Add a check for this situation and set the timeout to
Integer.MAX_VALUE when overflow happens.

If an application uses PushConnection directly on the native Git wire
protocols JGit should send along the application's expected oldId, not
the advertised value. This allows the remote peer to compare-and-swap
since it was not tested inside JGit.
Discovered when I tried to use a PushConnection (bypassing the
standard PushProcess) and the client blindly overwrote the remote
reference, even though my app had supplied the wrong ObjectId for
the expectedOldObjectId. This was not expected and cost me over an
hour of debugging, plus "corruption" in the remote repository.
By passing along the exact expectedOldObjectId from the app the
remote side can do the check that the application skipped, and
avoid data loss.
