[MAJOR] merged the 'setbe' actions to switch the backend on a regex
Sin Yu's patch to permit to change the proxy from a regex was merged
with little changes :
- req_cap/rsp_cap are not reassigned to the new proxy, they stay
attached to the frontend
- the actions have been renamed "reqsetbe" and "reqisetbe" for
"set BackEnd".
- the buffer is not reset after the switch, instead, the headers are
parsed again by the backend
- in Sin's patch, it was theorically possible to switch multiple times,
but the switching track was lost, making it impossible to apply
server responsesin the reverse order. Now switching is limited to
1 action (separation between frontend and backend) but the filters
remain.
Now it will be extremely easy to add other switching conditions, such
as host matching, URI matching, etc...
There's still a hard work to be done on the logs and stats.
