When in OURS and THEIRS a new file is created we want a conflict
when the two contents differ. If on two branches the same file
with the same content is created this should not be a conflict.
But: the current merge algorithm is throwing NPEs in this case.
Fix this by choosing an empty RawText as common base if the
base is empty.

If the object type is a whole object and all we want is the type,
there is no need to skip the length header. The type is already known
and can be returned as-is. Instead skip the length header only for
the two delta formats, where the delta base must itself be scanned.

This variable was not used for anything, but Eclipse's JDT failed to
notice because of the "shift += " operation within the body of the
while loop. Here we don't need the shift because we do not decode the
length, but we do have to skip over the bytes that store the length to
locate the delta base.

If the CLI stops a rebase upon conflict, the current
step is already popped from the git-rebase-todo and appended to the
"done" file. The current implementation wrongly pops the step only
after successful cherry-pick.

The referenced bug showed that JGit produced different merge results
compared to C Git. Unit test was added to reproduce the issue. The
problem can be solved by switching to histogram diff algorithm.

The diff algorithm which is used by Merge, Cherry-Pick, Rebase
should be configurable. A new configuration parameter "diff.algorithm"
is introduced which currently accepts the values "myers" or
"histogram". Based on this parameter for example the ResolveMerger
will choose a diff algorithm. The reason for this is bug 331078.
This bug shows that JGit is more compatible with C Git when
histogram diff is in place. But since histogram diff is quite new we
need an easy way to fall back to Myers diff.

There was a bug introduced by commit 0e815fe. For non-versioned files
the merge algorithm detected an incoming deletion from THEIRS.
Consequently such files were deleted. That's a severe bug which was
fixed by more precisely detecting incoming deletions.

Instead of copying up to 4 fields from the parent iterator each time a
child iterator is initialized and used, construct a single state
object that contains the 4 fields, and pass that one state object
through to the child. This makes it easier to add additional state
fields that must be inherited, at the slight expense of an extra
object allocation per TreeWalk, and an extra level of field
indirection whenever the options, nameEncoder, or read buffer is
required by the iterator.

In the case where DirCacheCheckout was used to checkout a tree
without taking HEAD into account (e.g. during a clone or hard reset)
we didn't handle conflicts correctly. E.g. if there are conflicts
(entries with stage != 0) in the index and we tried to hard reset
we have been processing the conflicting pathes multiple times (once
for every stage). With this fix we will update the index with the
entry from the "merge" state (the state we want checkout) when we
detect existing conflicts.

Since we have already modified this class to localize an error
message, we might as well strip it down to contain only the
functionality we need, or might ever use.
To keep this simple to review we don't adjust formatting right
away, so code that was buried inside of an if or else block whose
condition was removed might not have the correct indentation anymore.
We can fix this with a later reformatting change.
