1493         (ctf_free_base): Removed, ctf_base is no longer freed: free

1499         longer track old and new headers separately.  No longer allow for
1500         header sizes explicitly: squeeze the headers out on upgrade (they
1501         are preserved in fp->ctf_header).  Set ctf_dynbase, ctf_base and
1502         ctf_buf explicitly.  Use ctf_free, not ctf_free_base.

1509         the ctf_buf unless that buf is derived unmodified from the input.
1510         Set ctf_dynbase where ctf_base is dynamically allocated. Drop locals
1511         that duplicate fields in ctf_file: move allocation of ctf_file
1512         further up instead.  Call upgrade_header as needed.  Move
1513         version-specific ctf_parmax initialization into upgrade_types.  More
1514         concise error handling.
1515         (ctf_file_close): No longer test for null pointers before freeing.
1516         Free ctf_dyncuname, ctf_dynbase, and ctf_header.  Do not call

1524         (ctf_compress_write): Get the header from ctf_header, not ctf_base.
1525         Fix the compression length: fp->ctf_size never counted the CTF
1526         header.  Simplify the compress call accordingly.

1530         * ctf-endian.h: Don't assume htole64 and le64toh are always
