will downgrade in the next commit.)

two major bugs:
- off-by-one overflow when the length of the source string exceeds or
equals the destination buffer size.
- old version was not padding the destination buffer with null wide chars
This removes a lot of complexity, since we basically just reserve
space on a retrieval of a label, and pass around strings. Two new
elements: (1) consumers of the API must now declare what label
elements they are interested in retrieving, or (2) rely on the default
provided in a new configuration file, mac.conf.

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

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.
