Couple of points wrt Jetty 9 upgrade changes

- Jetty9 API Changes - Jetty 9 API has changed significantly from 8.x
hence it would not be possible to create two jars from same project
- Java 7 requirement - Jetty 9 requires Java 7 for compilation

Given that changing the symbolic name would cause extra work for users
when upgrading the HTTP bundle it would be helpful to retain the
bundle symbolic name. Based on suggestions above I think we can do
following

- Branch the current code in jetty module [1] at same level say
http://svn.apache.org/repos/asf/felix/trunk/http/jetty9. So kind of
branching but instead of branching to felix/branches we branch
locally. Otherwise we can also create a branch at [2].
- Retain the Bundle-SymbolicName but bump the major version to 3.0.x
- Future releases from current jetty module would stick to 2.x series
while from Jetty9 would be 3.x series
- Changes other than those in jetty and itest module can be done in
compatible way. So those module should be able to work with both
Jetty8 and Jetty9

If we have an agreement there I can rework the patch in FELIX-4550
