Update build to use CBI jarsigner plugin

The dash signing plugin has been retired hence we need to update our
build to use the CBI jarsigner plugin for signing build results.

Pack test classes to enable signing them.

Also re-enable pack200 for bundle org.eclipse.jgit.

WORKAROUND: there is no easy way to run tests with maven-surefire-plugin
from signed test-jar so for a quick workaround we will have to add a
build step on Hudson so that we can run tests before signing:
- first step will do "clean, verify" to compile and run tests
- second step will do "install, deploy" with profile "eclipse-sign" and
  use -DskipTests=true to skip tests since they would hit a
  SecurityException when unsigned test classes are in same package as
  signed classes under test
- third step will do "clean, install, deploy" on packaging reactor to
  build features and p2 repository with profile "eclipse-sign" to sign
  and pack200 all bundles.

TODO: Tycho doesn't suport picking up pack200 artifacts via
pomDependencies hence we need to find a way to copy them manually and
use tycho-extra's tycho-p2-extras-plugin:publish-features-and-bundles
to generate the missing p2 metadata.

Remove unnecessary inflate stride in DfsBlock

OpenJDK 7 does not benefit from using an inflate stride on the input
array. The implementation of java.util.zip.Inflater supplies the
entire input byte[] to libz, with no regards for the bounds supplied.
Slicing at 512 byte increments in DfsBlock no longer has any benefit.

In OpenJDK 6 the native portion of Inflater used GetByteArrayRegion
to obtain a copy of the input buffer for libz. In this use case
supplying a small stride made sense, it avoided allocating space
for and copying data past the end of the object's compressed stream.

In OpenJDK 7 the native code uses GetPrimitiveArrayCritical,
which tries to avoid copying by freezing Java garbage collection
and accessing the byte[] contents in place. On OpenJDK 7 derived
JVMs it is likely more efficient to supply the entire DfsBlock.

Since OpenJDK 5 and 6 are deprecated and replaced by OpenJDK 7
it is reasonable to suggest any consumers running JGit with DFS
support use an OpenJDK 7 derived JVM. However, JGit still targets
local filesystem support on Java 5, so it is still not reasonble to
apply this same simplification to the internal.storage.file package.
