bundle2: support for bundling parameter value

Parameter can now have a value. We use a `<name>=<value>` form inspired from
capabilities.

There is still no kind of escaping in the name or value, yet.

:params value: arbitrary number of Bytes

  A blob of `params size` containing the serialized version of all stream level
  parameters.

  The blob contains a space separated list of parameters.

  Parameter value are not supported yet.

  Special character in param name are not supported yet.

  Stream parameters use a simple textual format for two main reasons:

        yield '\0\0'
