libctf, dedup: add deduplicator
This adds the core deduplicator that the ctf_link machinery calls (possibly repeatedly) to link the CTF sections: it takes an array of input ctf_file_t's and another array that indicates which entries in the input array are parents of which other entries, and returns an array of outputs. The first output is always the ctf_file_t on which ctf_link/ctf_dedup/etc was called: the other outputs are child dicts that have the first output as their parent. include/ * ctf-api.h (CTF_LINK_SHARE_DUPLICATED): No longer unimplemented. libctf/ * ctf-impl.h (ctf_type_id_key): New, the key in the cd_id_to_file_t. (ctf_dedup): New, core deduplicator state. (ctf_file_t) <ctf_dedup>: New. <ctf_dedup_atoms>: New. <ctf_dedup_atoms_alloc>: New. (ctf_hash_type_id_key): New prototype.

(ctf_add_encoded): No longer static. (ctf_add_reftype): Likewise. * ctf-open.c (ctf_file_close): Destroy the ctf_dedup_atoms_alloc. * ctf-dedup.c: New file. * ctf-decls.h [!HAVE_DECL_STPCPY]: Add prototype. * configure.ac: Check for stpcpy. * Makefile.am: Add it. * Makefile.in: Regenerate. * config.h.in: Regenerate. * configure: Regenerate.
