Sort all libtool symbol lists

The original plan for the libtool symbol lists was that they be in
alphabetical order. This should make them easier to maintain, as it
becomes harder to accidentaly introduce duplicates, and makes merge
conflicts when adding new symbols less likely.

However, not all of them are properly sorted. Update the ones that
aren't. This was done with

    for A in `find . -name *.la.sym`; do sort $A -o $A; done
