core: delay focus updates

Delay focus updates until critical section. Rational is that focus
events might arrive when the focused window hasn't been managed by
compton, result in that that window not being focused.

This commit makes compton mark focus update events, and only update
focus in critical section, after we managed all the new windows.

Fixes #177
