Throw BinaryBlobException from RawParseUtils#lineMap.
This makes detection of binaries exact for ResolveMerger and
DiffFormatter: they will classify files as binary regardless of where
the '\0' occurs in the text.

This method creates a RawText from a blob, but avoids reading the blob
if the start contains null bytes. This should reduce the amount of
garbage that Gerrit produces for changes with binaries.

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.

A few classes such as Constanrs are marked with @SuppressWarnings, as are
toString() methods with many liternal, but otherwise $NLS-n$ is used for
string containing text that should not be translated. A few literals may
fall into the gray zone, but mostly I've tried to only tag the obvious
ones.

RawText#getEOL() does the same thing as RawText#getLineDelimiter()
The duplication has been introduced when merging
I08e1369e142bb19f42a8d7bbb5a7d062cc8533fc and
I18adc63596f4657516ccc6d704a561924c79d445. The former should have been
manually rebased. It also missed a copyright update in ApplyCommandTest.

When in OURS and THEIRS a new file is created we want a conflict
when the two contents differ. If on two branches the same file
with the same content is created this should not be a conflict.
But: the current merge algorithm is throwing NPEs in this case.
Fix this by choosing an empty RawText as common base if the
base is empty.

These routines can be useful when debugging, because we can add an
expression to the Eclipse "Expressions" panel to show the text that
appears on a line. Gerrit Code Review also uses these in its own
subclass of RawText in order to format patch files, so pulling it up
to be part of core JGit may help other applications too.

Remove dead RawText(RawTextComparator) constructor
Since the introduction of HashedSequence we no longer need to supply
the RawTextComparator at the time of constructing a RawText. Drop the
definition from the constructor, because it doesn't make sense as part
of our public API.

Most diff implementations really want to use cached hash codes for
elements, rather than element equality, as they need to perform many
compares and unique hash codes for elements can really speed that
process up.
To make it easier to define element hash functions, move the caching
of hash codes into a wrapper sequence type, so that individual
sequence types like RawText don't need to do this themselves. This
has a nice property of also allowing the sequence to no longer care
about the specific SequenceComparator that is going to be used, and
permits the caching to only examine the middle region that isn't
common to the two inputs.

Instead of making the sequence itself responsible for the equivalence
function, use an external function that is supplied by the caller.
This cleans up the code because we now say cmp.equals(a, ai, b, bi)
instead of a.equals(ai, b, bi).
This refactoring also removes the odd concept of creating different
types of sequences to have different behaviors for whitespace
ignoring. Instead DiffComparator now supports singleton functions
that apply a particular equivalence algorithm to a type of sequence.

We know exactly how many lines we need by the time we compute our
per-line hashes, as we have already built the lines IntList to give
us the starting position of each line in the buffer. Using that
we can properly size the array, and don't need the dynamic growing
feature of IntList. So drop the indirection and just use a fixed
size array.

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.]

Similar to what we did with diff, implement whitespace ignore options
for log too. This requires us to define some means of creating any
RawText object type at will inside of DiffFormatter, so we define a
new factory interface to construct RawText instances on demand.
Unfortunately we have to copy the entire block of common options.
args4j only processes the options/arguments on the one command class
and Java doesn't support multiple inheritance.

Added a check in Diff to ensure that files that are most likely
not text are not line-by-line diffed. Files are determined to be
binary by checking the first 8000 bytes for a null character. This
is a similar heuristic to what C Git uses.

Ensure RawText closes the FileInputStream when read is complete
Rather than implementing the file reading logic ourselves, and
wind up leaking the FileInputStream's file descriptor until the
next GC, use IO.readFully(File) which wraps the read loop inside
of a try/finally to ensure the stream is closed before it exits.

Add javadoc comments, remove unused code, shift comments to correct place
This change only fixes warnings of the eclipse build regarding missing javadocs.
Some comments where just missing, so they have been added. Other comments where
at the wrong (from eclipse point of view) place, so eclipse was complaining.
Also two method which existed for debugging purposes have been removed to get
rid of Eclipse warngins about unused code.
Per CQ 3448 this is the initial contribution of the JGit project
to eclipse.org. It is derived from the historical JGit repository
at commit 3a2dd9921c.
