Add initial regression test suite.

Don't AC_SUBST a dozen different FOO_CFLAGS and FOO_LIBS. Instead, incrementally build up just CAIRO_CFLAGS and CAIRO_LIBS.
Don't list flags that should get picked up via dependency information through Requires.
Add description of move_to_show_surface.

+ *   It looks like cairo_show_surface has no effect if it follows a
+ *   call to cairo_move_to to any coordinate other than 0,0. A little
+ *   bit of poking around suggests this isn't a regression, (at least
+ *   not since the last pixman snapshot).
