When RecursiveMerger found that there are multiple base-commits for the
commits to be merged it tries to temporarily merge the base commits. But
if these base commits have no common predecessor there was a bug in JGit
leading to a NPE. This commit fixes this by enforcing that an empty tree
is used as base when merging two unrelated base commits.
This logic was already there when merging two commits which have no
common predecessor (ThreeWayMerger.mergeBase()). But the code which was
computing a new temporary base commit in case of criss-cross merges
didn't take care to pick an empty tree when no common predecessor can be
found.

This reverts commit 6bc48cdc62.
Until git v1.7.10.2~29^2~1 (builtin/merge.c: reduce parents early,
2012-04-17), C git merge would make merge commits with duplicate parents
when asked to with a series of commands like the following:
git checkout origin/master
git merge --no-ff origin/master
Nowadays "git merge" removes redundant parents more aggressively
(whenever one parent is an ancestor of another and not just when
duplicates exist) but merges with duplicate parents are still permitted
and can be created with git fast-import or git commit-tree and history
viewers need to be able to cope with them.
CommitBuilder is an interface analagous to commit-tree, so it should
allow duplicate parents. (That said, an option to automatically remove
redundant parents would be useful.)

The block pointer list may have been relatively large, so no need to
make more garbage. Instead, just clear the list and null out all the
elements.
Another possible motivation: a caller may have provided an inaccurate
estimated size, so the list might have been resized several times. If
the list is reused later for a similarly underestimated workload, this
fix will prevent additional resizing on subsequent usages.

Callers may wish to use TemporaryBuffer as an essentially unbounded
buffer by passing Integer.MAX_VALUE as the size. (This makes it
behave like ByteArrayOutputStream, only without requiring contiguous
memory.) Unfortunately, it was always allocating an array in the
backing block pointer list to hold enough blocks to MAX_VALUE--all
262,016 of them. It wasn't allocating the blocks themselves, but this
array was still extremely wasteful, using about 2MiB of memory on a
64-bit system.
Tweak the interface to specify an estimated size, and only allocate
the block pointer list enough entries to hold that size. It's an
ArrayList, so if that estimate was wrong, it'll grow. We assume the
cost of finding enough contiguous memory to grow that array is
acceptable.
While we're in there, fix an off-by-one error: due to integer division
we were undercounting the number of blocks needed to store n bytes of
data as (n / SZ).

Since 27ae8bc65 Git has implemented AutoCloseable, which means Eclipse
may warn if close() is never called on a Git instance. For example,
the following would result in a resource warning:
Repository repo = openRepository(foo);
Git git = new Git(repo);
try {
git.someCommand().call();
} finally {
repo.close();
}
(The same warning would occur if repo were created in a try-with-
resources block.)
The "obvious" fix is to open git in a try-with-resources block:
try (Repository repo = openRepository(foo);
Git git = new Git(repo)) {
git.someCommand().call();
}
Unfortunately, this construction was subtly broken: it would call both
git.close() and repo.close(), but git.close() would call repo.close()
again. Depending on the repository implementation, this might or might
not be ok. If it's not ok, it might not immediately cause an error, if
the reference count of repo was >2 at the time of closing.
Of course, explicitly calling git.close() followed by repo.close() in
two finally blocks has had the same double-closing problem since
forever. But the problem became worse when Git started implementing
AutoCloseable, because now Eclipse is _actively encouraging_
developers to change working code into broken code.
To work around this, keep track in Git's constructor of whether the
repository was passed in or opened at construction time, and only
close the repository if it was opened by Git.
Note that in the original example, there was not _actually_ a resource
leak, since repo was closed exactly once; git did not _need_ to be
closed in this case. But at least fixing this false-positive warning
no longer introduces a real bug.

Current ArchiveCommand design doesn't allow to pass in options to
underlying stream implementations. To overcome this, client has to
implement custom format implementation (it cannot be derived from
the existing one, because the classes are marked as final), and set
the options using ThreadLocal, before the method
ArchiveOutputStream createArchiveOutputStream(OutputStream s)
is get called.
This change extends the ArchiveCommand.Format by allowing to pass
option map during creation of ArchiveOutputStream.
ArchiveCommand is extended correspondingly. That way client can
easily pass options to the underlying streams:
Map<String, Object> level = ImmutableMap.<String, Object> of(
"level", new Integer(9));
new ArchiveCommand(repo)
.setFormat("zip")
.setFormatOptions(level)
.setTree(tree)
.setPaths(paths)
.setPrefix(prefix)
.setOutputStream(sidebandOut)
.call();
