New allout revisions, rectify byte-compilation related bug

[Ken Manheimer]

The attached patch rectifies a few allout problems, including a
critical bug on file save (and autosave).  That problem was due to a
macro being defined below its use - not a problem if the file is
byte-compiled when the macro definition is already evaluated, eg
during casual development, but that hides the problem which *does*
occur when the byte-compilation happens during emacs build, sigh.

I've also attached a ChangeLog entry.   No new NEWS is necessary.
