So that we can use the strings in ".strtab" directly, without duplicating them
on the global strings table.

Such as signed, etc. This is in preparation for using directly ctf_strings.
Instead of duplicating it in the global strings table.

Encoding all the non UNDEF OBJECT entries in the symtab. Some must be filtered
in upcoming patches, but for at least kernel/sched.o it works just fine.
To test it I used DaveM's ctfdump and also pdwtags on a --strip-debug, pahole
-Z CTF encoded object.

Moving more CTF only stuff out of the dwarves land and into something that can
be more easily stolen by other projects not interested in funny named stuff
such as pahole.
This also will help with encoding, as we will normally be recoding data from
DWARF, so the ELF file will be available and we will just add a new section to
it.

The ctf_loader.c file should be a direct counterpart to dwarf_loader,
that is, it should have just use what is in libctf to decode the CTF
sections and convert it to the core format in dwarves.[ch].
Also introduce a ctf__string32 for the very common idiom:
ctf_string(ctf__get32(sp->ctf, &tp->base.ctf_name), sp);

"pahole -Z foo" will create foo.SUNW_ctf, that if objcopy
--add-section'ed to the right word-sized object will work, sans VARARGS,
that will get fixed soon (as in, probably, tomorrow).
