Happily, most anonymous SectionParser implementations can be replaced
with FooConfig::new, as long as the constructor takes a single Config
arg. Many of these, the non-public ones, can in turn be inlined. A few
remaining SectionParsers can be lambdas.

Enable and fix 'Should be tagged with @Override' warning
Set missingOverrideAnnotation=warning in Eclipse compiler preferences
which enables the warning:
The method <method> of type <type> should be tagged with @Override
since it actually overrides a superclass method
Justification for this warning is described in:
http://stackoverflow.com/a/94411/381622
Enabling this causes in excess of 1000 warnings across the entire
code-base. They are very easy to fix automatically with Eclipse's
"Quick Fix" tool.
Fix all of them except 2 which cause compilation failure when the
project is built with mvn; add TODO comments on those for further
investigation.

TreeWalk provides the new method getEolStreamType. This new method can
be used with EolStreamTypeUtil in order to create a wrapped InputStream
or OutputStream when reading / writing files. The implementation
implements support for the git configuration options core.crlf, core.eol
and the .gitattributes "text", "eol" and "binary"

The change includes comparing symbolic links between disk and index,
adding symbolic links to the index, creating/modifying links on
checkout. The behavior is controlled by the core.symlinks setting, just
as C Git does. When a new repository is created core.symlinks will be
set depending on the capabilities of the operating system and Java
runtime.
If core.symlinks is set to true, the assumption is that symlinks are
supported, which may result in runtime errors if this turns out not to
be the case.
Measuring the cost of jgit status on a repository with ~70000 files,
of which ~30000 are tracked reveals a penalty of about 10% for using
the Java7 (really NIO2) support module.

There is a huge performance issue when using both JGit (EGit) and Git
because JGit does not fill all dircache stat fields with the values Git
would expect. As a result thereof Git would typically revalidate a large
number of tracked files. This can take several minutes for large
repositories with many large files.
Since 1.8.2 Git will restrict stat checking to the size and whole second
part of the modification time stamp, if core.statinfo is set to
"minimal".
As JGit checks only size and modification time this is close to what
JGit already does. To make the match perfect ignore the sub-second part
of the modification time stamp if core.statinfo = minimal.

Refactor IndexPack to not require local filesystem
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.

To improve runtime performance, caching the WorkingTreeOptions inside
of the Config object using the Config.SectionParser API allows
the WorkingTreeOptions to be accessed more efficiently whenever a
FileTreeIterator is constructed for the Repository.
Instead of passing the filemode handling option into isModified(),
the WorkingTreeIterator should always honor whatever setting has
been configured in this repository, as defined by its own copy of
the WorkingTreeOptions. This simplifies all of the callers as they
no longer need to lookup core.filemode on their own.
A few locations were changed from always using a hardcoded "true"
on the file mode to passing what is actually configured in the
repository. This is a behavior change, but corrects what should be
considered to be bugs as the core.filemode variable wasn't always
being used.

The core.autocrlf variable can take on three values: false, true,
and input. Parsing it as a boolean is wrong, we instead need to
parse a tri-state enumeration.
Add support for parsing and setting enum values from Java from and
to the text based configuration file, and use that to handle the
autocrlf variable.

Instead of getting the limit from CoreConfig, use the larger of the
reader's limit or 5 MiB, under the assumption that any annotated tag
or commit of interest should be under 5 MiB. But if a repository
was really insane and had bigger objects, the reader implementation
can set its streaming limit higher in order to allow RevWalk to
still process it.

Perform automatic CRLF to LF conversion during WorkingTreeIterator
WorkingTreeIterator now optionally performs CRLF to LF conversion for
text files. A basic framework is left in place to support enabling
(or disabling) this feature based on gitattributes, and also to
support the more generic smudge/clean filter system. As there is
no gitattribute support yet in JGit this is left unimplemented,
but the mightNeedCleaning(), isBinary() and filterClean() methods
will provide reasonable places to plug that into in the future.
[sp: All bugs inside of WorkingTreeIterator are my fault, I wrote
most of it while cherry-picking this patch and building it on
top of Marc's original work.]

Use core.streamFileThreshold to set our streaming limit
We default this to 1 MiB for now, but we allow users to modify
it through the Repository's configuration file to be a different
value. A new repository listener is used to identify when the
setting has been updated and trigger a reconfiguration of any
active ObjectReaders.
To prevent a horrible explosion we cap core.streamFileThreshold
at no more than 1/4 of the maximum JVM heap size. We do this
because we need at least 2 byte arrays equal in size to the
stream threshold for the worst case delta inflation scenario,
and our host application probably also needs some amount of the
heap for their working set size.

Refactor object writing responsiblities to ObjectDatabase
The ObjectInserter API permits ObjectDatabase implementations to
control their own object insertion behavior, rather than forcing
it to always be a new loose file created in the local filesystem.
Inserted objects can also be queued and written asynchronously to
the main application, such as by appending into a pack file that
is later closed and added to the repository.
This change also starts to open the door to non-file based object
storage, such as an in-memory HashMap for unit testing, or a more
complex system built on top of a distributed hash table.
To help existing application code port to the newer interface we
are keeping ObjectWriter as a delegation wrapper to the new API.
Each ObjectWriter instances holds a reference to an ObjectInserter
for the Repository's top-level ObjectDatabase, and it flushes and
releases that instance on each object processed.

Add support for logAllRefUpdates configuration parameter
Honor the configuration parameter core.logAllRefUpdates when writing
reflogs. Instead of writing reflog entries always only write
reflogs if this parameter is set to true or if the corresponding
file in the <git-dir>/logs directory already exists. In other words:
if you are updating a ref and this parameter is set to false and
there is no file corresponding to your ref in the <git-dir>/logs
folder then no reflog will be written.
This is a fix for the issue http://code.google.com/p/egit/issues/detail?id=4
