This came up while testing the proposed buck build for jgit. With buck
we can introduce smaller modules to allow for more concurrency during
build and to better control inner structure of jgit. Trying to put the
porcelain API into a different module than lower level implementation
classes failed since RebaseTodoLine used a porcelain API exception
causing a dependency cycle on the proposed modules. Using an exception
defined on the same abstraction level fixes this problem.

Add recursive variant of Config.getNames() methods
These methods allow to find all configuration entry names for a given
section or section/subsection searching recursively through all base
configurations of the given configuration.
These methods are needed to calculate the names for the effective
configuration of a git repository which combines the configuration entry
names found in the repository, global and system configuration files

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).

Do not allow non-ff-rebase if there are uncommitted changes
With this change jgit checks for uncommitted changes before a rebase is
started. This is also done by native git. One reason is that an abort
would override such changes. The check is skipped for a non-interactive
rebase when it will result in a fast-forward. In this case there can be
only checkout conflicts but no merge conflicts, so there cannot be an
abort which overrides uncommitted changes.

Fix handling of file/folder conflicts during a checkout
JGit was not handling certain file/folder conflicts during a checkout
correctly. This was reported by Axel Richard in
http://dev.eclipse.org/mhonarc/lists/jgit-dev/msg02358.html.
This commit fixes this problem.
Still JGit behaves intentionally different than native git.
If HEAD contains a tree, and workingtree, Index and Merge contain a file
with same content ... then JGit allows a conflict free checkout of
Merge. Native git always complains that it doesn't want to overwrite
local changes. But there is no need to update the working tree because
Index and Merge are already equal.
A shell script which shows how native git behaves can be found here.

Don't delete .idx file if .pack file can't be deleted
If during an garbage collection old packfiles are deleted it could
happen that on certain platforms the index file can be deleted but the
packfile can't be deleted (because someone locked the file). This led
to repositories with packfiles without corresponding index files. Those
zombie-packfiles potentially consume a lot of space on disk and it is
never tried to delete them again. Try to avoid this situation by
deleting packfiles first and don't try to delete the other files if we
can't delete the packfile. This gives us the chance to delete the
packfile during next GC.
This commit only improves the situation - there is still the chance for
orphan files during packfile deletion. We don't have an atomic delete
of multiple files .

squash or fixup a soft reset to the parent is perfomed afterwards.

Parse commitId and shortMessage of a commented out line in rebase todo
A rebase todo file consists of regular non-comment action lines and
comment lines. In case that a regular action line has been commented out
(i.e. prefixed with a hash '#'), the RebaseTodoLine that is representing
this line should hold the values for commitId and shortMessage even
though it's a comment line. This allows to switch between comment and
non-comment easily even after the file has been persisted and reread.

Enhance reading of git-rebase-todo formatted files
Reading and writing files formatted like the git-rebase-todo files was
hidden in the RebaseCommand. Certain constructs (like leading tabs and
spaces) have not been handled as in native git. Also the upcoming
rebase interactive feature in EGit needs reading/writing these files
independently from a RebaseCommand.
Therefore reading and writing those files has been moved to the
Repository class. RebaseCommand gets smaller because of that and doesn't
have to deal with reading/writing files.
Additional tests for empty todo-list files, or files containing comments
have been added.

In C Git 1.8.2, "git reset" now also works on an unborn branch (no HEAD

This can be useful for callers because "unborn branch" no longer has to
