This partially reverts 1e7aaed8bc keeping the conversion
functions from/to move to uci string in the same file.
No functional change.

And also store the node counter in Position and not in Thread.
This will allow to properly count nodes also in sub trees with
SMP active.
This requires a surprisingly high number of changes
in a lot of places to make it work properly.
No functional change but node count changed for obvious reasons.

In move_to_san() we create by copy a new position just
to detect if move gives check. This could be very costly in
line_to_san() that calls move_to_san() for every move, so
create the position only once and pass a reference to move_to_san()
No functional change.

Make a copy of the position when needed instead
of passing as a reference. It is cleaner and
let us to simplify also Position::print()
A small space inflate while there.
