Move checkPath from DirCacheCheckout to ObjectChecker
The bulk of the "is this sane" logic is inside of ObjectChecker. The

the static isValidRefName() method in Repository.
Deprecate the weird single use method in DirCacheCheckout and move all

Use baseline instead of centerline in PlotRenderer
If the text extent height of a to be rendered plot line is odd, then the
SWTPlotRenderer cannot calculate the correct Y position for drawing the
label and draws the label with a 1 pixel offset. SWT text drawing uses
the baseline as Y coordinate. Due to the given centerline API in the
AbstractPlotRenderer the overall calculation of the baseline for SWT is
effectively (height / 2) * 2, thereby rounding all odd heights downward
to the next even number.
This change pushes the division by 2 from the caller into the
implementations of drawText. A corresponding change will be pushed in
the egit repository.

JGit's ObjectDirectory implements the optimization that it remembers the
pack folders (.git/objects/pack) lastModified timestamp and doesn't
check for new packfiles in this folder if the lastModified attribute has
not changed.
In environments using NFS this can cause trouble. If multiple JGit
instances from multiple machines work on the same repository and one
instance creates a new ref and a new packfile (e.g. by doing a fetch)
then the other machines may detect the new ref but can't resolve the
referenced object because it doesn't detect that pack folder has a new
packfile. That's because NFS may cache file/folder metadata for quite a
long time and the pack folders modification time is not updated although
a new packfile is there and could be read.
The new config parameter core.trustfolderstat controls this behaviour.
The default is true and jgits behaviours is unchanged. But if this
parameter is set to false then jgit doesn't trust the pack directories
lastmodified anymore. Instead it will always iterate through the content
of that folder to detect new packfiles.

RebaseCommand should ignore submodule modifications
Before a rebase happens the RebaseCommand checks that the working tree
is clean. We don't want to start a rebase on a dirty working tree. If
the working tree is dirty a rebase should not be allowed. But
RebaseCommand should ignore modifications done to submodules. E.g. if a
submodules HEAD points to <x> but the root repository has in index that
the submodule should point to <y> then this should not prohibit a
rebase. Also native git allows a rebase in this case. Since jgit's
StatusCommand has learned to ignore submodule changes this is now used
by the RebaseCommand to determine the repository state correctly.
Support for Submodule configuration submodule.<name>.ignore
For each submodule native git allows to configure which modifications to
submodules should be ignored by the status command. It is possible to
ignore "none", "all", "dirty", "untracked" [1]. This configuration is
now supported by IndexDiff. The StatusCommand offers the possibility to
specify this mode.

When writing new packs it should be allowed to specify objects as "have"
(objects which should not be included in the pack) which do not exist in
the local repository.
This works with the traditional PackWriter, but when PackWriter was
working on a repository with bitmap indexes and used
PackWriterBitmapWalker then this feature was broken. Non-existing "have"
objects lead to MissingObjectExceptions. That broke push and Gerrit
replication. When the replication target had branches unknown to the
replication source then the source repository wanted to build pack files
where "have" included branch-tips which were unknown in the source
repository.
