ObjectInserter recently learned to read back inserted objects before
they have been flushed. It is in general unsafe to create refs to such
objects, but it is now much more possible to do so, by passing "new
RevWalk(inserter.newReader())" into RefUpdate#execute(RevWalk).
We can't change the RefUpdate interface to remove execute(RevWalk);
nor would we necessarily want to, for performance reasons. And in any
case, RefUpdate#safeParse explicitly ignores MissingObjectExceptions.
But we can enforce object existence in InMemoryRepository, which will
allow callers using this class in their tests to ensure they are using
the RefDatabase correctly.

In case the index contains wrong tree extensions don't throw a
ArrayIndexOutOfBounds exception but revalidate the tree extension.
It happened that the git index written by Git for Windows contained valid
(means entryCount>0) tree extensions for pathes which are not existing
in the index. Native git handles this inconsistency silently but JGit
was crashing with a ArrayIndexOutOfBounds exception. Teach JGit to
better recognize such cases and revalidate such extensions.
It's hard to write a test because JGit doesn't write such extensions. It
only reads, validates and makes use of them. But the bug tells how to
create such situations.

Don't remove pack from pack list for problems which could be transient

If we hit a corrupt object or invalid pack remove the pack from the pack
list. Other IOException could be transient hence we should not remove
the pack from the list to avoid the problem reported on the Gerrit list
[1]. It looks like in the reported case the pack was removed from the
pack list causing MissingObjectExceptions which disappear when the
server is restarted.

The atomic feature is now cooking in -next in git-core. Very rarely
features are ejected from the the next branch in git-core, so I consider
it reasonable to come up with this patch now to make the 2 implementations
interoperable.

The path matcher should not fail if the rule ends with trailing slash,
target pattern does not ends with the slash and the "assumeDirectory"
flag is set.
E.g. */bin/ should also match a/bin if this pattern is threated as
directory by WorkingTreeIterator (FileMode.TREE).
The old code/tests have never tested directory rules with patterns
*without* trailing slashes but with the "assumeDirectory" flag set.
Unfortunately this is exactly what WorkingTreeIterator does... The tests
are changed to test *both* cases now (with trailing slash and without)
if the target pattern has trailing slash (represents directory).

SystemReader used a chached ObjectChecker which was instantiated only
once. But in case of unit tests where we can change the platform
dynamically (e.g. MockSystemReader.setWindows()) this is wrong and
caused DirCacheCheckoutMaliciousPathTest.
testMaliciousAbsoluteCurDrivePathWindowsOnUnix() to fail. This change
allows
user of SystemReader to force the creation of a new ObjectChecker.
MockSystemReader.setWindows() and .setUnix() make use of this feature.

Windows creates shortnames for all non-8.3 files (see [1]). Hence we
need to disallow all names which could potentially be a shortname for
".git". Example: in an empty directory create a folder "GIT~1". Now you
can't create another folder ".git".
The path "GIT~1" may map to ".git" on Windows. A potential victim to
such an attack first has to initialize a git repository in order to
receive any git commits. Hence the .git folder created by init will get
the shortname "GIT~1". ".git" will only get a different shortname if the
user has created a file "GIT~1" before initialization of the git
repository.
