Assume a (possibly buggy) `unset' is present after a `better shell' was found.
* lib/autoconf/general.m4 (_AC_CACHE_DUMP): Use AS_UNSET.
* lib/autoconf/programs.m4 (AC_PROG_SED): Use AS_UNSET.
* lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Provide $as_unset as an
alias for AS_UNSET, for backwards compatibility.
(_AS_DETECT_BETTER_SHELL): Set BASH_ENV and ENV to /dev/null in case
the shell does not support unset.
(_AS_SHELL_SANITIZE): Work around Bash 2.01 bugs. Unset BASH_ENV.
(AS_INIT, _AS_PREPARE, AS_PREPARE): Call it.
(AS_UNSET): Assume it is there but it might fail if the variable is
not set. Use it throughout instead of $as_unset.
