Monitoring progress of merges can be useful for users for large
repositories or complex merge processes that take some time.
This enables setting a monitor. Existing merge implementations in jgit
do not yet report progress if a monitor is set. This will be added in a
later change.

When there are conflicts with a recursive merge, the conflicting paths
are stored in unmergedPaths (field in ResolveMerger). Later, when the
MergeResult is constructed in MergeCommand, getBaseCommit is called,
which computes the merge base a second time.
In case of RecursiveMerger, getBaseCommit merges the multiple merge
bases into one. It does this not by creating a new ResolveMerger but
instead calling mergeTrees. The problem with mergeTrees is that at the
end, it checks if unmergedPaths is non-empty and returns false in that
case.
Because unmergedPaths was already non-empty because of the real merge,
it thinks that there were conflicts when computing the merge base again,
when there really were none.
This can be fixed by storing the base commit when computing it and then
returning that instead of computing it a second time.
Note that another possible fix would be to just use a new ResolveMerger
for merging the merge bases instead. This would also remove the need to
remember the old value of dircache, inCore and workingTreeIterator (see
RecursiveMerger#getBaseCommit).

Make recursive merge strategy the default merge strategy
Use recursive merge as the default strategy since it can successfully
merge more cases than the resolve strategy can. This is also the default

Git API does not declare GitAPIException call() and related cleanups
All commands should throw a GitAPIException so new exceptions can be
added without breaking the builds of old code, i.e. anyone that calls
a Git API should catch GitAPIException and not just the currently known
exceptions.
Now the only checked exceptions on Git API calls are GitException and
subclasses of it. New checked exceptions that are subclasses of
GitException may be added without breaking the API.
Javadoc for GitAPIException is declared on GitCommand and
inherited to subclasses. JGitInternalException is not explicitly
documented anymore.
Unfortunately this change itself breaks the API. The intention is
that it shall be possible to add new checked subclasses of
GitAPIException without breaking the API.

org.eclipse.jgit.api.errors.CheckoutConflictException which it

If HEAD exists but points to an not-existing branch the merge
command should silently create the missing branch and check
it out. This happens if you pull into freshly initalized repo.
HEAD points to refs/heads/master but refs/heads/master doesn't
exist. If you know merge a commit X into HEAD then the branch
master should be created (pointing to X) the working tree should
be updated to reflect X. That is achieved by checkout with one
tree only (HEAD is missing).
A test for this functionality will come the the next proposal
in PullCommandTest.

Instead of making the sequence itself responsible for the equivalence
function, use an external function that is supplied by the caller.
This cleans up the code because we now say cmp.equals(a, ai, b, bi)
instead of a.equals(ai, b, bi).
This refactoring also removes the odd concept of creating different
types of sequences to have different behaviors for whitespace
ignoring. Instead DiffComparator now supports singleton functions
that apply a particular equivalence algorithm to a type of sequence.

This adds the first merge strategy to JGit which does real
content-merges if necessary. The new merge strategy "resolve" takes as
input three commits: a common base, ours and theirs. It will simply takeover
changes on files which are only touched in ours or theirs. For files
touched in ours and theirs it will try to merge the two contents
knowing taking into account the specified common base.
Rename detection has not been introduced for now.

Update a number of calling sites of RevWalk to ensure the walker's
internal ObjectReader is released after the walk is no longer used.
Because the ObjectReader is likely to hold onto a native resource
like an Inflater, we don't want to leak them outside of their
useful scope.
Where possible we also try to share ObjectReaders across several
walk pools, or between a walker and a PackWriter. This permits
the ObjectReader to actually do some caching if it felt inclined
to do so.
Not everything was updated, we'll probably need to come back and
update even more call sites, but these are some of the biggest
offenders. Test cases in particular aren't updated. My plan is to
move most storage-agnostic tests onto some purely in-memory storage
solution that doesn't do compression.
