The crash occurs if a slot causes the very next slot in iteration order
to be disconnected.
Relanding after fixing a race condition that this CL revealed. Previously
the race resulted in an invalidated iterator, but now it will result in the
iterator being modified, so TSan catches it.

Reason for revert:
Revealed a race condition (now reported by TSan), and breaks the scenario where a signal is deleted while firing.

They used to work, but were broken by a somewhat recent refactoring of
sigslot.h.
It's reasonable for signals and slots to have copy constructors, since
a class that uses signals/slots may want to be copyable.

This reduces binary size considerably and solves some other problems.
Also rewrote using variadic templates.
