[daisy] New Daisy repository runtime platform

[Bruno Dumon]

Another update:

The main work on the new runtime is done. It still resides on
BRANCH_NEWRUNTIME, but I'm planning on merging it to trunk later this
week. The work has gone quicker and smoother than I expected, in part
because I've opted for completely backwards compatible component
configuration.

The switch to the new runtime should have no noticeable impact to users:

 * behind the scenes, instead of merlin, the new runtime is started

 * configuration (myconfig.xml) stays the same

Custom written authentication schemes will have to be adjusted, but the
change is straightforward and it will be a lot easier. You will now be
able to just drop the jar containing the custom authentication scheme in
a <datadir>/extensions directory, and it will be loaded automatically
(on repository startup).

Of course, I'll write some documentation explaining all this.
