Bring r21919-21924 from trunk to 1.8 branch: cleanup FUNC_ENTER macros,
etc.
Also removed Subversion mergeinfo tags from a few directories and files.
These are artifacts from non-root merges using pre-1.6 Subversion clients. (This
should fix the problem of unchanged directories looking "changed" during
checkins.)
Tested on:
Mac OSX/64 10.7.3 (amazon) w/debug & production
(daily tested on trunk)
