display-pixel behavior changed on Mac OS X

[Ryan McGeary]

I just recently upgraded from 22.0.95 to 22.0.97.
x-display-pixel-width and x-display-pixel-height no longer work as
expected when running two displays.

(x-display-pixel-width) now returns the total width in pixels for all
displays/monitors, not just the main display for the frame.

For example, I have two displays side by side (1920x1200 and
1400x900).  In 22.0.95, x-display-pixel-width returned 1920 as
expected.  Now, 22.0.97 returns 3360 (1920 + 1400).  This was
unexpected and makes it difficult to use these values to auto-maximize
my initial emacs frame to fit the main display.
