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

Remove more unused stuff.
Also removed session::xinerama_scrs, since all the information we need
is covered by xinerama_scr_regs. Convert uses of xinerama_scrs to use
xinerama_scr_regs.

It used to be unmap when we receive its MapNotify, but now since we discard
events received before we grab X server, that event it lost. But it
turns out we can just unmap it when it's first created, no need to wait
for the MapNotify.
Partially fix#160

When a window is reparented to the same parent again, we should just
move it to the top of the stack, instead of add it again.
Also a slight refactor restack_win.

Currently compton handles window creation event by immediately query all
the information it needs and create a window struct with that
information. However, this is prone to race conditions.
In the future, we want to react to window creation event by creating a
placeholder in the window stack, and only query window information in a
critical section where the X server is grabbed by us.
This commit split struct win into two struct, one as placeholder, the
other for holding actual window information.
