Jonas Ådahl 2f4a68c8c3 Clean up include macros mess
The order and way include macros were structured was chaotic, with no
real common thread between files. Try to tidy up the mess with some
common scheme, to make things look less messy.

/* Looks up the MetaWindow representing the frame of the given X window.
* Used as a helper function by a bunch of the functions below.
*
* FIXME: The functions that use this function throw the result away
* after use. Many of these functions tend to be called in small groups,
* which results in get_window() getting called several times in succession
* with the same parameters. We should profile to see whether this wastes
* much time, and if it does we should look into a generalised
* meta_core_get_window_info() which takes a bunch of pointers to variables
* to put its results in, and only fills in the non-null ones.
