When a command invoked from readPipe fails to launch (i.e. the exec call
fails due to a missing command executable), Process.start() throws,
which gets caught by the generic IOException handler, resulting in a
null return. This change detects this case and rethrows a
CommandFailedException instead.

Additionally, this change uses /bin/sh instead of bash for its posix
command failure test, to accomodate building in environments where bash
is unavailable.

- enhance FS.readPipe to throw an exception if the external command
fails to enable the caller to handle the command failure
- reduce log level to warning if system git config does not exist
- improve log message

Since 4.0 JGit does no longer support Java versions older than Java 7 so
there is no need anymore to mention Java 7 in the class name.

The class FS_Win32 was always trying out to create a temporary symlink
in order to find out whether symlinks are supported. FS_Win32_Cygwin was
overwriting this method and always returned true. But when the user
running JGit does not have administrative rights then the creation of
symlinks is forbidden even if he is running on FS_Win32_Cygwin. A lot of
tests failed only on the Windows platform because of this. It was
correctly detected that FS_Win32_Cygwin is the filesystem abstraction to
be used but creation of symlinks always failed because of lacking
privileges of the user running the tests.

This fix teaches FS_Win32_Cygwin to behave like FS_Win32 and to test
whether symlinks can be created in order to find out whether symlinks
are supported.

Avoid always calling `sh -c umask` on startup, instead deferring
the invocation until the first time a working tree file needs to
use the execute bit. This allows servers using bare repos to avoid
a costly fork+exec for a value that is never used.

Store the umask as an int instead of two Boolean. This is slightly
smaller memory (one int vs. two references) and makes it easier for
an application to force setting the umask to a value that overrides
whatever the shell told JGit.

Simplify the code to bail by returning early when canExecute is
false, which is the common case for working tree files.

As we moved minimum Java version to 7 we don't need a separate bundle
and feature for JGit features depending on Java 7 anymore.

Buck does not create a target directory for the build output, this
is Maven specific and the project unit tests should not rely on it.

Instead follow the pattern used by org.eclipse.jgit.test which is to
create a temporary directory in the system temporary folder, and
configure the Maven surefire plugin to use the target directory.

The most important difference is that in Java7 we have symbolic links
and for most operations in the work tree we want to operate on the link
itself rather than the link target, which the old File methods generally
do.

We also add support for the hidden attribute, which only makes sense
on Windows and exists, just since there are claims that Files.exists
is faster the File.exists.

A new bundle is only activated when run with a Java7 execution
environment. It is implemented as a fragment.

Tycho currently has no way to conditionally include optional features
based on the java version used to run the build, this means with this
change the jgit packaging build always needs to be run using java 7.

All commands should throw a GitAPIException so new exceptions can be
added without breaking the builds of old code, i.e. anyone that calls
a Git API should catch GitAPIException and not just the currently known
exceptions.

Now the only checked exceptions on Git API calls are GitException and
subclasses of it. New checked exceptions that are subclasses of
GitException may be added without breaking the API.

Javadoc for GitAPIException is declared on GitCommand and
inherited to subclasses. JGitInternalException is not explicitly
documented anymore.

Unfortunately this change itself breaks the API. The intention is
that it shall be possible to add new checked subclasses of
GitAPIException without breaking the API.

Eclipse has some problem re-running single JUnit tests if
the tests are in Junit 3 format, but the JUnit 4 launcher
is used. This was quite unnecessary and the move was not
completed. We still have no JUnit4 test.

This completes the extermination of JUnit3. Most of the
work was global searce/replace using regular expression,
followed by numerous invocarions of quick-fix and organize
imports and verification that we had the same number of
tests before and after.

- Annotations were introduced.
- All references to JUnit3 classes removed
- Half-good replacement for getting the test name. This was
  needed to make the TestRngs work. The initialization of
  TestRngs was also made lazily since we can not longer find
  out the test name in runtime in the @Before methods.
- Renamed test classes to end with Test, with the exception
  of TestTranslateBundle, which fails from Maven
- Moved JGitTestUtil to the junit support bundle

This is a simple HTTP server that provides the minimum server side
support required for dumb (non-git aware) transport clients.

We produce the info/refs and objects/info/packs file on the fly
from the local repository state, but otherwise serve data as raw
files from the on-disk structure.

In the future we could better optimize the FileSender class and the
servlets that use it to take advantage of direct file to network
APIs in more advanced servlet containers like Jetty.

Our glue package borrows the idea of a micro embedded DSL from
Google Guice and uses it to configure a collection of Filters
and HttpServlets, all of which are matched against requests using
regular expressions.  If a subgroup exists in the pattern, it is
extracted and used for the path info component of the request.
