[PATCH 1/1] libctf: introduce ctf_func_type_{info,args}, ctf_type_aname_raw

[Nick Alcock]

(This precedes the ld series, which I will rebase atop it, because I
expect it to take longer to review the ld series than this one patch.)

On 18 Jul 2019, Nick Alcock spake thusly:

> The first two of these allow you to get function type info and args out
> of the types section give a type ID: astonishingly, this was missing
> from libctf before now: so even though types of kind CTF_K_FUNCTION were
> supported, you couldn't find out anything about them.  (The existing
> ctf_func_info and ctf_func_args only allow you to get info about
> functions in the function section, i.e. given symbol table indexes, not
> type IDs.)
