basetransform: should try to reconfigure on not-negotiated

Description
+++ This bug was initially created as a clone of Bug 681198 +++
basetransform (e.g. videoconvert, videoscale) should try to reconfigure itself on not-negotiated if a reconfiguration is pending.
Possibly even retry with the same buffer... (keeping a buffer ref doesn't force unnecessary memory copies downstream any more now, does it?)
