- Code simplification

* rpn.c: add "services_discovery_add", "services_discovery_remove" and "services_discovery_is_loaded" rpn functions.

The new format is disabled by default,
so we have little risks of regression.

--mosaic-keep-picture with a picture that is bigger than on of the

AAAAAABBB
A    ABBB
A    ACCC
AAAAAACCC
(where A, B and C are 3 sub streams)
