Nick Alcock 72c83edd92 libctf: add the ctf_link machinery 
This is the start of work on the core of the linking mechanism for CTF
sections.  This commit handles the type and string sections.

The linker calls these functions in sequence:

ctf_link_add_ctf: to add each CTF section in the input in turn to a
  newly-created ctf_file_t (which will appear in the output, and which
  itself will become the shared parent that contains types that all
  TUs have in common (in all link modes) and all types that do not
  have conflicting definitions between types (by default).  Input files
  that are themselves products of ld -r are supported, though this is
  not heavily tested yet.

ctf_link: called once all input files are added to merge the types in
  all the input containers into the output container, eliminating
  duplicates.

ctf_link_add_strtab: called once the ELF string table is finalized and
  all its offsets are known, this calls a callback provided by the
  linker which returns the string content and offset of every string in
  the ELF strtab in turn: all these strings which appear in the input
  CTF strtab are eliminated from it in favour of the ELF strtab:
  equally, any strings that only appear in the input strtab will
  reappear in the internal CTF strtab of the output.

ctf_link_shuffle_syms (not yet implemented): called once the ELF symtab
  is finalized, this calls a callback provided by the linker which
  returns information on every symbol in turn as a ctf_link_sym_t.  This
  is then used to shuffle the function info and data object sections in
  the CTF section into symbol table order, eliminating the index
  sections which map those sections to symbol names before that point.
  Currently just returns ECTF_NOTYET.

ctf_link_write: Returns a buffer containing either a serialized
  ctf_file_t (if there are no types with conflicting definitions in the
  object files in the link) or a ctf_archive_t containing a large
  ctf_file_t (the common types) and a bunch of small ones named after
  individual CUs in which conflicting types are found (containing the
  conflicting types, and all types that reference them).  A threshold
  size above which compression takes place is passed as one parameter.
  (Currently, only gzip compression is supported, but I hope to add lzma
  as well.)

Lifetime rules for this are simple: don't close the input CTF files
until you've called ctf_link for the last time.  We do not assume
that symbols or strings passed in by the callback outlast the
call to ctf_link_add_strtab or ctf_link_shuffle_syms.

Right now, the duplicate elimination mechanism is the one already
present as part of the ctf_add_type function, and is not particularly
good: it misses numerous actual duplicates, and the conflicting-types
detection hardly ever reports that types conflict, even when they do
(one of them just tends to get silently dropped): it is also very slow.
This will all be fixed in the next few weeks, but the fix hardly touches
any of this code, and the linker does work without it, just not as
well as it otherwise might.  (And when no CTF section is present,
there is no effect on performance, of course.  So only people using
a trunk GCC with not-yet-committed patches will even notice.  By the
time it gets upstream, things should be better.)

v4: check for strdup failure.
v5: fix tabdamage.

special-case the position of the parname string. Construct the
