Petals Distribution

The following modules depends on wsstar addressing:

• petals-bc-mail
• petals-bc-soap
• petals-sample-client

It is old and have a lot of old dependencies.
It seems to provides some utilities to handle WS-Addressing.

Our code mostly don't really exploit it:

• petals-bc-soap just tries to check if there is some ws-addressing field to know where to send a soap message (instead of using the address in the SU?)
• petals-sample-client just fill the ws-addressing field of a message if desired by the user
• petals-bc-mail exploits definition from ws-addressing to handle mail-oriented concepts (from, to, etc)

It seems that nothing actually exploits these (to be verified, especially for the bc mail, I didn't look in detail at it) and that it was some kind of work in progress to isolate some ws-addressing functionalities.

Advantages would be to clean a bit the dependencies we bring we petals and to not rely on an old unmaintained library.

Removing the dependency from petals-sample-client and petals-bc-soap is trivial, removing it from petals-bc-mail will need more understanding of it than I have for now
