Improve transparency detection for blur
...
Previously, only the WM windows (window manager usually reparents the
application windows under its own window so it can manage them) are
checked for alpha channels. Some of the window managers (e.g. awesome)
acquire alpha channels for all of the WM windows, whether the underlying
application windows have alpha channel or not.
With this change, the application windows are also checked for alpha
channels. If a WM window has alpha but its child doesn't, only the WM
frame will be considered to be semi-transparent. Thus preventing some
unnecessary blurring.

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.
