REORG: include: move filters.h to haproxy/filters{,-t}.h

Just a minor change, moved the macro definitions upwards. A few caller
files were updated since they didn't need to include it.

- *  - attach              : Called after a filter instance creation, when it is
- *                          attached to a stream. This happens when the stream
- *                          is started for filters defined on the stream's

- *                          Returns nothing.

- *                          to the client (mainly, when an error or a redirect
