---------------------------+------------------------------------------------
 I modified the b10-recurse to be configured by the config manager. It is
 possible to configure the addresses and ports it listens on and the
 addresses it forwards queries to. If it has no address to forward to, it
 is in recursive mode, if it has, it is in forward mode.

 It still has the -u and -v parameters. Currently, verboseness is global
 setting for single run of bind10 and will probably stay so until logging
 system is created. The -u will be dropped, since changing user is job for
 boss, not separate processes.

 The bind10 still takes -f to tell it to run recurse instead of auth,
 changing this is a different task.

 There are two problems. One is, it is impossible to change the listening
 sockets at runtime, as it is not possible to close the current ones
 (#388). The second is it is not possible to change the configuration
 trough bindctl, it doesn't handle properly configuring maps inside lists
 (#384). I suggest this should be left as separate tasks and this one
 revied and merged back to branches/trac327.

 The current code is in branches/vorner-recursor-config, between r3317 to
 r3353.

 I propose this changelog entry:

 {{{
 [func]    vorner
 The b10-recursive is configured trough config manager.
 It has "listen_on" and "forward_addresses" options.
 (trac389, SVN rTBD)
 }}}
