Use the correct constants directly from sysconf() rather than calling
sysctl() to tell us the (still compiled-in) value. Leave the CTL_POSIX1B
stuff alone for now (but I'd like to see this replaced with a single
structure returning all of the relevant information).
Implement all of the keys from 1003.1-2001 that we can. Ensure that
the build will break if someone redefines an option constant to zero
without implementing the necessary presence-detection logic here.

hack, thereby allowing future extensions to the structure (e.g., for extended
attributes) without rebreaking the ABI. FTSENT now contains a pointer to the
parent stream, which fts_compar() can then take advantage of, avoiding the
undefined behavior previously warned about. As a consequence of this change,
the prototype of the comparison function passed to fts_open() has changed
to reflect the required amount of constness for its use. All callers in the
tree are updated to use the correct prototype.
Comparison functions can now make use of the new parent pointer to access
the new stream-specific private data pointer, which is intended to assist
creation of reentrant library routines which use fts(3) internally.

to fail needlessly if a reverse DNS lookup of the IP address didn't
come up with a hostname. As a comment in the code clearly stated,
the "damn hostname" was looked up only for the purpose of netgroup
matching. But if that lookup failed, the function bailed out
immediately even though in many cases netgroup matching would not
be used.
This change marks the hostname as unknown but continues. Where
netgroup matching is performed, an unknown hostname is handled
conservatively. I.e., for "+@netgroup" (accept) entries an unknown
hostname never matches, and for "-@netgroup" (reject) entries an
unknown hostname always matches.
In the lines affected (only), I also fixed a few bogus casts. There
are others, and in fact this entire file would be a good candidate
for a cleanup sweep.
