	* ctf-open.c (ctf_set_base): Preserve the gap between ctf_buf and
	ctf_base: do not assume that it is always sizeof (ctf_header_t).
	Print out ctf_cuname: only print out ctf_parname if set.

	(upgrade_types_v1): ... this.  Free ctf_dynbase, not ctf_base.  No

	(upgrade_types): New, also handle ctf_parmax updating.
	(flip_header): Flip ctf_cuname.
	(flip_types): Flip BUF explicitly rather than deriving BUF from

	that duplicate fields in ctf_file: move allocation of ctf_file
	further up instead.  Call upgrade_header as needed.  Move
	version-specific ctf_parmax initialization into upgrade_types.  More
	concise error handling.
	(ctf_file_close): No longer test for null pointers before freeing.

	comment.
	(ctf_write): Likewise.

	special-case the position of the parname string.  Construct the
	strtab by calling ctf_str_add_ref and ctf_str_write_strtab after the
	rest of each buffer element is constructed, not via open-coding:
	realloc the CTF buffer and append the strtab to it.  No longer
	maintain ctf_dtvstrlen.  Sort the variable entry table later, after
	strtab construction.
	(ctf_copy_membnames): Remove: integrated into ctf_copy_{s,l,e}members.
	(ctf_copy_smembers): Drop the string offset: call ctf_str_add_ref
