Fixes the "Method ignores results of InputStream.read()" warning.
This is the only place where read() was used instead of readFully()
and the return value was not checked. So it was either an oversight
or should be documented. This change assumes it was an oversight.

As described in Bug 328551 there was a bug that the merge algorithm
was not always reporting conflicts when the same line was deleted
and modified. This problem was introduced during commit
0c017188b4 when reported conflicts have
been checked for common pre- and suffixes.
This was fixed here by better determining whether after stripping
off common prefixes and suffixes from a conflicting region there
is still some conflicting part left.
I also added a unit test to test this situation.

When creating a local branch based on another local branch, the
upstream configuration contains "." as origin and the source branch
as "merge". The PullCommand should support this by skipping the
fetch step altogether and use the base branch to merge with.

Don't permit transient worker threads to access the underlying output
stream of a ProgressMonitor, as they might get marked as the stream's
writer thread. Instead proxy update events from the workers back onto
the application's real work thread. This ensures that the stream only
sees a single thread, and its the thread that will remain alive for
the entire life cycle of the operation.
This fixes IOException("Write end dead") during local repository fetch
when threaded delta search is enabled. One of the transient delta
search threads became the designated writer for the pipe, and when it
terminated the reader end thought the writer was dead, even though the
main writer thread was still executing in PackWriter.

RefsDirectory fires a RefsChangedEvent when it detect that one
ref changed (new, modified, deleted). But there was a potential
of wrong events beeing fired leading to a endless loop in EGit.
Problem is that when calling getRefs(ALL) we don't want to report
additional refs and by that we remove the additional refs from
the list of "refs reported upwards last time". We fire an
RefsChangedEvent because we think that the special refs are not
there anymore.
I fixed this by removing eventing for the additional refs. Another
alternative would be to always scan also for additional refs and
put them in the list of refs. But getRefs(ALL) would then remove
the additional refs again. I didn't do that for performance reasons
and also because I am not sure whether we want evnting for
additional refs.

The RefDirectory class was not returning FETCH_HEAD and
MERGE_HEAD when trying to get all refs via getRefs(RefDatabase.ALL).
This fix adds constants for FETCH_HEAD and ORIG_HEAD and adds a
new getter getAdditionalRefs() to get these additional refs.
To be compatible with c git the getRefs(ALL) method will not return
FETCH_HEAD, MERGE_HEAD and ORIG_HEAD.

If an ObjectInserter is created from a CachedObjectDirectory, we need
to ensure the cache is updated whenever a new loose object is actually
added to the loose objects directory, otherwise a future read from an
ObjectReader on the CachedObjectDirectory might not be able to open
the newly created object.
We mostly had the infrastructure in place to implement this due to the
injection of unpacked large deltas, but we didn't have a way to pass
the ObjectId from ObjectDirectoryInserter to CachedObjectDirectory,
because the inserter was using the underlying ObjectDirectory and not
the CachedObjectDirectory. Redirecting to CachedObjectDirectory
ensures the cache is updated.

3rd party packages that use repository types other than FileRepository
may wish to extend our pgm package and implement their own resolution
scheme for repository "names" that are passed in by the --git-dir
command line option. Make that possible by allowing the package to
extend the Main class and override the lookup.
This is primarily useful when developing new storage implementations
and trying to experiment with the results, without linking all of it
into the core JGit package.

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.

When an empty line was inserted at the beginning of the common end
part of a RawText the comparator incorrectly considered it to be
common, which meant the DiffAlgorithm would later not even have it be
part of the region it examines. This would cause JGit to skip a line
of insertion, which later confused Gerrit Code Review when it tried to
match up the pre and post RawText files for a difference that had this
type of insertion.
Define two new unit tests to check for this insertion of a blank line
condition and correct for it by removing the LF from the common region
when the condition is detected.
