  tests: sanitize 'unset' usages
  
  In some shells (e.g., Solaris 10 /bin/ksh, or NetBSD 5.1 /bin/sh),
  "unset VAR" returns a non-zero exit status in case the VAR variable
  is already unset.  This doesn't interact well with our usage of
  "set -e" in the testsuite.  So far, we've avoided spurious failures
  by either explicitly ignoring the exit status from unset:
  
      unset VAR || :
  
  or explicitly ensuring that a variable is set, before trying to
  unset it:
  
      VAR=; unset VAR
  
  But we can do better, by aliasing the 'unset' command to a custom
  function that will take care of these details for us.  This will
  avoid us annoying spurious failures in the future, failures that
  have already bitten us too much times.  For an example, refer to
  commit 'v1.12.2-88-g5b1dae5' of 2012-08-05 (tests: avoid tons of
  spurious failures on NetBSD).
  
  * t/ax/test-lib.sh (_am_unset): New function.
  (unset): New alias to it.
  (_am_exit): Adjust comments.
  * t/ax/am-test-lib.sh: No need to temporary disable the 'errexit'
  shell flag when unsetting variables that are potentially already
  unset.
  (am_process_requirements): Adjust to remove a now-useless
  workaround related to unset.
