Variable handling in BTF and CTFv4 works quite differently from in CTFv3. Rather than a separate section containing sorted, bsearchable variables, they are simply named entities like types, stored in CTF_K_VARs. As a first stage towards migrating to this, delete most references to the ctf_varent_t and ctf_dvdef_t, including the DVD lookup code, all the linking code, and quite a lot of the serialization code. Note: CTF_LINK_OMIT_VARIABLES_SECTION, and the whole "delete variables that already exist in the symtypetabs section" stuff, has yet to be reimplemented. We can implement CTF_LINK_OMIT_VARIABLES_SECTION by simply excising all CTF_K_VARs at deduplication time if requested. (Note: symtypetabs should still point directly at the type, not at the CTF_K_VAR.) (Symtypetabs in general need a bit more thought -- perhaps we can now store them in a separate .ctf.symtypetab section with its own little four-entry header for the symtypetabs and their indexes, making .ctf even more like .BTF; the only difference would then be that .ctf could include prefix types, CTF_K_FLOAT, and external string refs. For later discussion.) We also add ctf_lookup_by_kind() at this stage (because it is hopelessly diff-entangled with ctf_lookup_variable): this looks up a type of a particular kind, without needing a per-kind lookup function for it, nor needing to hack around adding string prefixes (so you can do ctf_lookup_by_kind (fp, CTF_K_STRUCT, "foo") rather than having to do ctf_lookup_by_name (fp, "struct foo"): often this is more convenient, and anything that reduces string buffer manipulation in C is good.)
