some malloc cleanup.

e9cfb9ae3a Completely revamp the way getconf(1) works, for better adherence to the
intent of the Standard.

- Make getconf able to distinguish between configuration variables which
  are entirely unknown and those which are merely not defined in the
  compilation environment.  The latter now get a more appropriate
  "undefined\n" result rather than a diagnostic.  This may not be
  exactly right, but it's closer to the intent of the Standard than
  the previous behavior.

- Support ``programming environments'' by validating that the environment
  requested with the `-v' flag is the one-and-only execution environment.
  (If more environments are supported for some platforms in the future,
  multiple getconf(1) executables will be required, but a simple edit in
  progenv.gperf will enable automatic support for it.)  Document POSIX
  standard programming environments.

- Add all of the 1003.1-2001 configuration variables.  FreeBSD does not
  support all of these (including some that are mandatory); getconf will
  later be fixed to break the world should a required variable not be
  defined.

As a result of all these changes, gperf is no longer adequate.  Keep the
overall format and names of the files for now, to preserve revision history.
Use an awk script to process the .gperf files into C source, which does a
few things that gperf, as a more general tool, cannot do.  The keyword
recognition function is no longer a perfect hash function.

This may obviate the need for gperf in the source tree.

- Add a small compile-time regression test to break the build if any of the
  .gperf files declare conflicting token sets.  (gperf itself would have done
  this for the simple case of duplicate tokens in the same input file.)

8c6bd995f0 Hello, getconf. This is a slight reinvention of the
wheel^H^H^H^H^HPOSIX.2 and X/Open utility, and rather
more complicated than necessary.
