We cannot always rename read-only files on network shares,
so rename the temp file for a new loose object first, and
then set it as read-only.

When debugging and enhancing DirCacheCheckout.processEntry() I found
that some of if-statements where hard to read/understand. This
change just splits some long if statements and adds more comments
explaining in which state we are. This change is only a preparation
for followup commits which introduce checks for untracked+ignored
files.

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.

Add possibility to disable ssl verification, just as i can do with git
using: git config --global http.sslVerify false
To enable the feature, configure
Window->Preferences->Team->Git->Configuration
and add a new key/value: http.sslVerify=false
When handling repos over https, JGit will then check that flag to see
if security is loose and the ssl verification should be ignored.
Having it implemented as a key/value makes it not too obvious in the
GUI - so the user must know what he/she is doing when adding it. Being
aware of the risks etc.

Reading a repository for millions of missing objects might be very
expensive to perform, especially if the repository is on a network
filesystem or some other costly RPC backend. A repository owner
might choose to accept some risk in return for better performance,
so allow disabling collision checking when receiving a pack.
Currently there is no way for an end-user to disable this feature.
This is intentional, because it is generally *NOT* a good idea to
skip this check. Instead this feature is supplied for storage
implementations to bypass the default checking logic, should they
have their own custom routines that is just as effective but can
be handled more efficiently.

If a pack uses OFS_DELTA only (e.g. its an initial push to a
repository) and PackParser's implementation is broken such that the
delta chain that hangs below a particular object offset is empty, the
entryCount won't match the expected objectCount. Fail fast rather
than claiming the stream was parsed correctly.
The current implementation is not broken as described above. I broke
the code when I implemented my own new subclass of PackParser (which
incorrectly mucked with the object offset information), leading me to
discover this consistency check was missing.

By moving the logic that parses a pack stream from the network (or
a bundle) into a type that can be constructed by an ObjectInserter,
repository implementations have a chance to inject their own logic
for storing object data received into the destination repository.
The API isn't completely generic yet, there are still quite a few
assumptions that the PackParser subclass is storing the data onto
the local filesystem as a single file. But its about the simplest
split of IndexPack I can come up with without completely ripping
the code apart.

Additionally, defined the NoteMap.getNote method which returns a Note
instance. These changes were necessary to enable implementation of
the NoteMerger interface (the merge method needs to instantiate a
Note) and to enable direct use of NoteMerger which expects instances
of Note class as its paramters. Implementing creation of code review
summary notes in Gerrit [1] will make use of both of these features.

Merging Git notes branches has several differences from merging "normal"
branches. Although Git notes are initially stored as one flat tree the
tree may fanout when the number of notes becomes too large for efficient
access. In this case the first two hex digits of the note name will be
used as a subdirectory name and the rest 38 hex digits as the file name
under that directory. Similarly, when number of notes decreases a fanout
tree may collapse back into a flat tree. The Git notes merge algorithm
must take into account possibly different tree structures in different
note branches and must properly match them against each other.
Any conflict on a Git note is, by default, resolved by concatenating
the two conflicting versions of the note. A delete-edit conflict is, by
default, resolved by keeping the edit version.
The note merge logic is pluggable and the caller may provide custom
note merger that will perform different merging strategy.
Additionally, it is possible to have non-note entries inside a notes
tree. The merge algorithm must also take this fact into account and
will try to merge such non-note entries. However, in case of any merge
conflicts the merge operation will fail. Git notes merge algorithm is
currently not trying to do content merge of non-note entries.
Thanks to Shawn Pearce for patiently answering my questions related to
this topic, giving hints and providing code snippets.

Patterns containing only a trailing slash have to be treated
as "global" patterns. For example: "classes/" matches "classes"
as well as "dir/classes" directory.
When an application asks for the names in a section, it may want to
see the existing case that was stored by the user. For example,
Gerrit Code Review wants to store a configuration block like:
[access "refs/heads/master"]
label-Code-Review = group Developers
and although the name label-Code-Review is case-insensitive, it wants
to display the case as it appeared in the configuration file.
When enumerating section names or variable names (both of which are
case-insensitive), Config now keeps track of the string that first
appeared, and presents them in file order, permitting applications to
use this information. To maintain case-insensitive behavior, the
contains() method of the returned Set<String> still performs a
case-insensitive compare.
This is a behavior change if the caller enumerates the returned
Set<String> and copies it to his own Set<String>, and then performs
contains() tests against that, as the strings are now the original
case from the configuration block. But I don't think anyone actually
does this, as the returned sets are immutable and are cached.

Instead of using the current thread's stack to recurse through the
delta chain, use a linked list that is stored in the heap. This
permits the any thread to load a deep delta chain without running out
of thread stack space.
Despite needing to allocate a stack entry object for each delta
visited along the chain being loaded, the object allocation count is
kept the same as in the prior version by removing the transient
ObjectLoaders from the intermediate objects accessed in the chain.
Instead the byte[] for the raw data is passed, and null is used as a
magic value to signal isLarge() and enter the large object code path.
Like the old version, this implementation minimizes the amount of
memory that must be live at once. The current delta instruction
sequence, the base it applies onto, and the result are the only live
data arrays. As each level is processed, the prior base is discarded
and replaced with the new result.
Each Delta frame on the stack is slightly larger than the standard
ObjectLoader.SmallObject type that was used before, however the Delta
instances should be smaller than the old method stack frames, so total
memory usage should actually be lower with this new implementation.

Eclipse has some problem re-running single JUnit tests if
the tests are in Junit 3 format, but the JUnit 4 launcher
is used. This was quite unnecessary and the move was not
completed. We still have no JUnit4 test.
This completes the extermination of JUnit3. Most of the
work was global searce/replace using regular expression,
followed by numerous invocarions of quick-fix and organize
imports and verification that we had the same number of
tests before and after.
- Annotations were introduced.
- All references to JUnit3 classes removed
- Half-good replacement for getting the test name. This was
needed to make the TestRngs work. The initialization of
TestRngs was also made lazily since we can not longer find
out the test name in runtime in the @Before methods.
- Renamed test classes to end with Test, with the exception
of TestTranslateBundle, which fails from Maven
- Moved JGitTestUtil to the junit support bundle
