stats: preparatory change of the implementation of %c

Browse source 
This now holds the scc_info while processing the %c sequence, so that
using options we will soon be able to specify which SCC to count.

* spot/twaalgos/stats.hh, spot/twaalgos/stats.cc (printable_scc_info):
New class.
(state_printer): Use it for %c.
* spot/misc/formater.hh: Add move assignment.
* bin/common_aoutput.hh, bin/common_aoutput.cc: Use printable_scc_info
for %C.
* tests/core/format.test: Add a quick test case to make sure nothing
changed.
