Partially revert "xwm: Add icon support to the frame" and friends

Browse source 
This (partially) reverts commit bef761796c.
This (partially) reverts commit 4d1cd36c9e.
This (partially) reverts commit 44fc1be913.
This (partially) reverts commit 6b58ea8c43.

The new xwm icon code has proven to be leaky and incomplete, and while
we have patches under consideration to fix the rest of its known problems
they still require changes and review cycles.  Currently the known
leaks have been squashed, but it still picks wrong sized icons and
does no scaling, which can lead to very strange rendering.  At window
close time the wrong sized icon appears above the window during fade out.

This patch reverts the mostly solid bits and keeps the unfinished
bits behind in favor of a simpler revert than removing the whole
thing.
