Child commits always have a lane assigned when their parents are
processed, so this code is no longer necessary.
Children only assign themselves to parents in
PlotCommitList.setupChildren(), which is called from enter(), when the
child is processed. If the child leaves enter() it should always have a
lane assigned. As a result of this, when processing a parent, all its
known children already have lanes assigned. If the underlying RevWalk
emits a parent before one of its children (which it should not do), the
parent does not know of the child emitted later, because setupChildren()
has not been called for the child yet. So even in this case, no child
without a lane is encountered when processing a (parent) commit.

This also properly removes the newly determinded lane position from the
freePositions set in handleBlockedLanes(). closeLane() does only recycle
active lanes, to avoid recycling lanes twice.

Sun HttpURLConnection is able to handle authentication like SPNEGO without
caller intervention. However, there are some restrictions:
- do not need user direct input (user,password for example)
- it doesn't work when request body is chunked/streamed (because it cannot be
replayed)
Unfortunately there is no real way to leverage HttpURLConnection authentication
work as the authentication header is stripped off the request before returning
to the caller. There's also no way to explicitly disable authentication in
HttpURLConnection (SPNEGO auth will always be attempted if a valid token can be
created by GSSAPI).
This is an issue for jgit since it is expected that the first request will be
used to detect authentication method, and reuse for the subsequent requests.
This patch modifies TransportHTTP to detect authentication done in the background
by HttpURLConnection and sets the jgit authentication method accordingly so it will
always work for future requests (assuming that the authentication method used by
HttpURLConnection is also supported by jgit).

Adds a factory class for GSSManager. GSSManager is already a factory class but
it doesn't work well with SPNEGO HTTP authentication unless the
javax.security.auth.useSubjectCredsOnly system property is set to false.
On Sun JDK, Sun GSSManagerImpl can be configured directly for SPNEGO auth
(without setting any system property). For a better experience, the class
availability is detected by reflection and used instead.
Detection is only done once, and fallbacks to org.ietf.jgss.GSSManager.

This partially reverts 6de12836d7.
Performing a TreeWalk over 2 trees to identify and skip unmodified
subtrees to pass all blame onto an ancestor appears to be a micro
optimization that works for a very limited number of files. In the
general case the 2 tree walk is slowing down blame more than it helps
to speed it up.
I keep coming up with files in multiple repositories where 6de128 is
making things worse, not better, and only one example where it
actually improved performance, render_view_impl.cc in chromium
as described in the commit message.

In two places we threw an IOException and the message was built using
JGitText.couldNotWriteFile. We specified 2 parameters, but this pattern
expects only one parameter. In both places we tried to rename a file,
that's why we wanted two parameters (src and target) for the exception
text.
I changed it to use JGitText.renameFileFailed which accepts two
parameters and fits better.

Previously, setting any TreeFilter on a RevWalk triggered parent
rewriting, which in the current StartGenerator implementation ends up
buffering the entire commit history in memory. Aside from causing poor
performance on large histories, this does not match the default
behavior of `git rev-list`, which does not rewrite parent SHAs unless
asked to via --parents/--children.
Add a new method setRewriteParents() to RevWalk to disable this
behavior. Continue rewriting parents by default to maintain backwards
compatibility.

When blaming a merge commit with "Ignore whitespace changes" enabled,
don't discard blame candidates for other parents when we encounter a
parent that only has whitespace changes compared to the merge result.
The algorithm early prepares parents for blaming, removing the
appropriate blame regions from the list of regions still to blame. Only
at the end, the prepared blame candidates are submitted for blaming.
When looking at a non-first parent which only differs in whitespace to
the merge result, it submitted that parent, but only to blame it for the
(usually few) lines not already prepared to blame on other parents. Due
to an early return the blame candidates for the previous parents were
forgotten, leaving many lines unannotated.

With this commit running blame on render_view_impl.cc[1] saves
about 644 ms over prior versions, reducing the time about 4.5%.
Large projects often contain strands of commits where no changes
are made to a particular subtree. Blame used to dive recursively
into these subtrees to look for the blob and check if its SHA-1
was changed. In chromium/src[1] only 20% of the commits modify
the content/renderer subtree relevant for the file.
The recursivePath is necessary to check for '/' and remember
if common subtree elimination should be attempted. When a file
lives within a subtree the extra cost to check for unmodified
subtrees saves time. However for files in the root tree the
extra work incurred by TreeWalk is not worthwhile and would
significantly increase overall running time.
Now typical running times from an otherwise idle desktop:
real 0m13.387s 0m13.341s 0m13.443s

Avoid converting the raw mode to FileMode. This is an expensive
if-else-if sort of test to just check if the thing is a blob.
Instead test the bit mask directly, which is at least a few
instructions shorter.
The TreeWalk is already recursive and will auto-dive into any
subtrees found. isSubtree check is unnecessary, as is the loop,
as only one result will ever be returned by next().
