Nick Alcock 1136c37971 libctf: symbol type linking support 
This adds facilities to write out the function info and data object
sections, which efficiently map from entries in the symbol table to
types.  The write-side code is entirely new: the read-side code was
merely significantly changed and support for indexed tables added
(pointed to by the no-longer-unused cth_objtidxoff and cth_funcidxoff
header fields).

With this in place, you can use ctf_lookup_by_symbol to look up the
types of symbols of function and object type (and, as before, you can
use ctf_lookup_variable to look up types of file-scope variables not
present in the symbol table, as long as you know their name: but
variables that are also data objects are now found in the data object
section instead.)

(Compatible) file format change:

The CTF spec has always said that the function info section looks much
like the CTF_K_FUNCTIONs in the type section: an info word (including an
argument count) followed by a return type and N argument types. This
format is suboptimal: it means function symbols cannot be deduplicated
and it causes a lot of ugly code duplication in libctf.  But
conveniently the compiler has never emitted this!  Because it has always
emitted a rather different format that libctf has never accepted, we can
be sure that there are no instances of this function info section in the
wild, and can freely change its format without compatibility concerns or
a file format version bump.  (And since it has never been emitted in any
code that generated any older file format version, either, we need keep
no code to read the format as specified at all!)

So the function info section is now specified as an array of uint32_t,
exactly like the object data section: each entry is a type ID in the
type section which must be of kind CTF_K_FUNCTION, the prototype of
this function.

This allows function types to be deduplicated and also correctly encodes
the fact that all functions declared in C really are types available to
the program: so they should be stored in the type section like all other
types.  (In format v4, we will be able to represent the types of static
functions as well, but that really does require a file format change.)

We introduce a new header flag, CTF_F_NEWFUNCINFO, which is set if the
new function info format is in use.  A sufficiently new compiler will
always set this flag.  New libctf will always set this flag: old libctf
will refuse to open any CTF dicts that have this flag set.  If the flag
is not set on a dict being read in, new libctf will disregard the
function info section.  Format v4 will remove this flag (or, rather, the
flag has no meaning there and the bit position may be recycled for some
other purpose).

New API:

Symbol addition:
  ctf_add_func_sym: Add a symbol with a given name and type.  The
                    type must be of kind CTF_K_FUNCTION (a function
                    pointer).  Internally this adds a name -> type
                    mapping to the ctf_funchash in the ctf_dict.
  ctf_add_objt_sym: Add a symbol with a given name and type.  The type
                    kind can be anything, including function pointers.
		    This adds to ctf_objthash.

These both treat symbols as name -> type mappings: the linker associates
symbol names with symbol indexes via the ctf_link_shuffle_syms callback,
which sets up the ctf_dynsyms/ctf_dynsymidx/ctf_dynsymmax fields in the
ctf_dict.  Repeated relinks can add more symbols.

Variables that are also exposed as symbols are removed from the variable
section at serialization time.

CTF symbol type sections which have enough pads, defined by
CTF_INDEX_PAD_THRESHOLD (whether because they are in dicts with symbols
where most types are unknown, or in archive where most types are defined
in some child or parent dict, not in this specific dict) are sorted by
name rather than symidx and accompanied by an index which associates
each symbol type entry with a name: the existing ctf_lookup_by_symbol
will map symbol indexes to symbol names and look the names up in the
index automatically.  (This is currently ELF-symbol-table-dependent, but
there is almost nothing specific to ELF in here and we can add support
for other symbol table formats easily).

The compiler also uses index sections to communicate the contents of
object file symbol tables without relying on any specific ordering of
symbols: it doesn't need to sort them, and libctf will detect an
unsorted index section via the absence of the new CTF_F_IDXSORTED header
flag, and sort it if needed.

Iteration:
  ctf_symbol_next: Iterator which returns the types and names of symbols
                   one by one, either for function or data symbols.

This does not require any sorting: the ctf_link machinery uses it to
pull in all the compiler-provided symbols cheaply, but it is not
restricted to that use.

(Compatible) changes in API:
  ctf_lookup_by_symbol: can now be called for object and function
                        symbols: never returns ECTF_NOTDATA (which is
			now not thrown by anything, but is kept for
                        compatibility and because it is a plausible
                        error that we might start throwing again at some
                        later date).

Internally we also have changes to the ctf-string functionality so that
"external" strings (those where we track a string -> offset mapping, but
only write out an offset) can be consulted via the usual means
(ctf_strptr) before the strtab is written out.  This is important
because ctf_link_add_linker_symbol can now be handed symbols named via
strtab offsets, and ctf_link_shuffle_syms must figure out their actual
names by looking in the external symtab we have just been fed by the
ctf_link_add_strtab callback, long before that strtab is written out.
