Done last week:
* commited all bits from original patch except changes to struct
stat and struct dirent
* added a few more tweaks to shlib-compat so it can
handle missing symbols better
* fixed several issues in user space libs.

Next I'm going to add support for libraries without symbol versioning to
shlib-compat and run it on all shared libraries installed. I'd like to
add symbol versioning to other libs if needed. I'll also commit rest of
the patchset.
