Specifically, some new ctf_get_ctt_* functions are added, and new LCTF_* macros are added to use the underlying container's version to do the right thing. CTF containers can have parent/child relationships, wherein a type ID in one container refers to a type in the parent. It is permitted for the parent and child to have different versions.

Specifically: - Type IDs are now encoded in 32 bits rather than 16, changing the layout of ctf_type_t, ctf_array_t, ctf_member_t and ctf_lmember_t. - Type info is encoded in 32 bits rather than 16. The type "kind" is extended from 5 bits to 6, and the type "vlen" is extended from 10 bits to 25. The main upside is that we remove the current limit, imposed by CTFv2, of 2^{15} distinct types in the main kernel executable. Other limits, such as that on the number of elements in an enum, imposed by the vlen limit, are also raised. This change adds v2 and v3 flavours of macros and type definitions which differ between the two versions. Compatibility is preserved for now by having generic names refer to the v2 definitions, so, e.g., ctf_type_t is still a v2 type. No functional change intended.

This makes it easier to use CTF in the core kernel, and to extend the CTF format to support wider type IDs. The imported ctf.h is modified to depend only on _types.h, and also to provide macros which use the "parent" bit of a type ID to refer to types in a parent CTF container. No functional change intended.
