When CommitCommand.setOnly(path) is used a temporary index has to be
created containing only modifications for the specified pathes. The
process to fill this temporary index was broken because filling the
index was stopped when we reached the first untracked file. Instead the
process to fill the temporary index should continue until we processed
all pathes.

Cleanup code and Eclipse compile errors in new gitrepo API
Commit d3348e introduced few errors in Eclipse.
This commit cleans up the new API:
- fixes API error in RepoCommand after moving IncludedFileReader type
- fixes unused imports in RepoCommand & RepoCommandTest
- fix javadoc errors in ManifestParser & RepoProject
- makes three (implicitly final) fields in ManifestParser final.

The LRU chain management code was broken leading to situations where
the chain was incomplete. This prevented the cache from removing
items when it exceeded its memory target, causing a leak.
One case was repeated hit on the head of the chain. moveToHead(e)
was invoked linking the head back to itself in a cycle orphaning
the rest of the table.
Add some unit tests to cover this and a few other paths.

FS_POSIX: Rework umask detection to make it settable
Avoid always calling `sh -c umask` on startup, instead deferring
the invocation until the first time a working tree file needs to
use the execute bit. This allows servers using bare repos to avoid
a costly fork+exec for a value that is never used.
Store the umask as an int instead of two Boolean. This is slightly
smaller memory (one int vs. two references) and makes it easier for
an application to force setting the umask to a value that overrides
whatever the shell told JGit.
Simplify the code to bail by returning early when canExecute is
false, which is the common case for working tree files.

Despite being the primary author of RevWalk and ObjectWalk I still
fail to remember to setRetainBody(false) in application code using
an ObjectWalk to examine the graph.
Document the default for RevWalk is setRetainBody(true), where the
application usually wants the commit bodies to display or inspect.
Change the default for ObjectWalk to setRetainBody(false), as nearly
all callers want only the graph shape and do not need the larger text
inside a commit body. This allows some code in JGit to be simplified.

Add fsck.allowInvalidPersonIdent to accept invalid author/committers
A larger than expected number of real-world repositories found on
the Internet contain invalid author, committer and tagger lines
in their history. Many of these seem to be caused by users misusing
the user.name and user.email fields, e.g.:
[user]
name = Au Thor <author@example.com>
email = author@example.com
that some version of Git (or a reimplementation thereof) copied
directly into the object header. These headers are not valid and
are rejected by a strict fsck, making it impossible to transfer
the repository with JGit/EGit.
Another form is an invalid committer line with double negative for
the time zone, e.g.
committer Au Thor <a@b> 1288373970 --700
The real world is messy. :(
Allow callers and users to weaken the fsck settings to accept these
sorts of breakages if they really want to work on a repo that has
broken history. Most routines will still function fine, however
commit timestamp sorting in RevWalk may become confused by a corrupt
committer line and sort commits out of order. This is mostly fine if
the corrupted chain is shorter than the slop window.

Fix RecursiveMerger in case of multiple, independent base commits
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.

CherryPickCommand only works on a non-bare repository, as it must
modify the working tree and index in case of a merge conflict. In
tests, being able to recover from a merge conflict is less important,
as the caller should be able to control the full contents of files in
advance of the cherry-pick.

Revert "CommitBuilder should check for duplicate parents"
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.)

TemporaryBuffer: Allow presizing block pointer list
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).

ArchiveCommand: Allow to pass options to underlying stream
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();
