Nick Alcock 087945261c libctf: fix some tabdamage and move some code around 
ctf-link.c is unnecessarily confusing because ctf_link_lazy_open is
positioned near functions that have nothing to do with opening files.

Move it around, and fix some tabdamage that's crept in lately.

indexed, sorted symtypetab (and allow SYMFP to be NULL in this
case). Turn sorting off if this is a non-final link. Only delete

reported some.
