TreeWalk calls this value "path", while "name" is the stuff after the
last slash.  FileHeader should do the same thing to be consistent.
Rename getOldName to getOldPath and getNewName to getNewPath.

This better matches with the name used in the environment
(GIT_WORK_TREE), in the configuration file (core.worktree),
and in our builder object.

Since we are already breaking a good chunk of other code
related to repository access, and this fairly easy to fix
in an application's code base, I'm not going to offer the
wrapper getWorkDir() method.

The mapCommit API is being deprecated because it doesn't run very
fast.  Leaving tests around to test how fast it is relative to C Git
isn't instructive.  Remove them, which should help aid the transition
away from the mapCommit API.

On Windows, FS_Win32_Cygwin has been used if a Cygwin Git installation
is present in the PATH. Assuming that the user works with the Cygwin
Git installation may result in unnecessary overhead if he actually
does not.

Applications built on top of jgit may have more knowledge on the
actually used Git client (Cygwin or not) and hence should be able to
configure which FS to use accordingly.

Later we are going to add support for smart HTTP, which requires us to
buffer at least some of the request created by a client before we ship
it to the server.  For many requests, we can fit it completely into a
1 MiB buffer, but if it doesn't we can drop back to using the chunked
transfer encoding to send an unknown stream length.

Rather than recoding the block based memory buffer, we refactor the
local file overflow strategy into a subclass, allowing the HTTP client
code to replace this portion of the logic with its own approach to
start the chunked encoding request.

This test depends upon the external git binary, and this isn't
really a pure Java test like our module tries to claim itself is.
So we move it out to exttst with other tests that require additional
external resources and/or executable 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.
