Fix computation of id in WorkingTreeIterator with autocrlf and smudging
JGit failed to do checkouts when the index contained smudged entries and
autocrlf was on. In such cases the WorkingTreeIterator calculated the
SHA1 sometimes on content which was not correctly filtered. The SHA1 was
computed on content which two times went through a lf->crlf conversion.
We used to tell the treewalk whether it is a checkin or checkout
operation and always use the related filters when reading any content.
If on windows and autocrlf is true and we do a checkout operation then
we always used a lf->crlf conversion on any text content. That's not
correct. Even during a checkout we sometimes need the crlf->lf
conversion. E.g. when calculating the content-id for working-tree
content we need to use crlf->lf filtering although the overall operation
type is checkout.
Often this bug does not have effects because we seldom compute the
content-id of filesystem content during a checkout. But we do need to
know whether a file is dirty or not before we overwrite it during a
checkout. And if the index entries are smudged we don't trust the index
and compute filesystem-content-sha1's explicitly.
This caused EGit not to be able to switch branches anymore on Windows
when autocrlf was true. EGit denied the checkout because it thought
workingtree files are dirty because content-sha1 are computed on wrongly
filtered content.

HugeFileTest: Make Git a class member and open in try-with-resource
There's only one test method in this module and it's quite long, so
rather than using a try-with-resource and having to indent a huge
block of existing code, make the Git a member variable that gets
initialised and closed in @Before and @After annotated methods.
The methods are named 'before' and 'after' rather than the conventional
'setUp' and 'tearDown' so as not to conflict with the names of the
existing methods in LocalDiskRepositoryTestCase.

Add option to allow empty commits to CommitCommand
CommitCommand should allow to specify whether empty commits (commits
having the same tree as the sole predecessor commit) are allowed or not.
Similar to native git's "--allow-empty" flag.
The defaults differ between JGit and native git even after this change.
When not specifying paths then by default JGit allows to create empty
commits while native git does not. It would be API breaking to change
this now.

Repository: Introduce exactRef and findRef, deprecate getRef
The Repository class provides only one method to look up a ref by
name, getRef. If I request refs/heads/master and that ref does not
exist, getRef will look further in the search path:
ref/refs/heads/master
refs/heads/refs/heads/master
refs/remotes/refs/heads/master
This behavior is counterintuitive, needlessly inexpensive, and usually
not what the caller expects.
Allow callers to specify whether to use the search path by providing
two separate methods:
- exactRef, which looks up a ref when its exact name is known
- findRef, which looks for a ref along the search path
For backward compatibility, keep getRef as a deprecated synonym for
findRef.
This change introduces findRef and exactRef but does not update
callers outside tests to use them yet.

Treat CloneCommand.setRemote(null) as setRemote("origin")
A non-bare clone command with null remote produces a
NullPointerException when trying to produce a refspec to fetch against.
In a bare repository, a null remote name is accepted by mistake,
producing a configuration with items like 'remote.url' instead of
'remote.<remote>.url'. This was never meant to work.
Instead, let's make setRemote(null) undo any previous setRemote calls
and re-set the remote name to DEFAULT_REMOTE, imitating C git clone's
--no-origin option.
While we're here, add some tests for setRemote working normally.
