- unset_builtin: add shell compatibility level check <= bash-5.1 to
force `unset a[@]' to unset array variable `a', like in previous
versions, instead of unsetting associative array element `@' or
removing all elements of an indexed array without unsetting the
variable itself

- set_expand_once: now a no-op if the shell compatibility level is
<= bash-5.1, preserving the previous versions' behavior for [[ -v

- parameter_brace_expand_rhs: make sure that the final value assigned
is always returned from ${a:=b}, even when `a' has a variable
attribute that modifies the value on assignment. Reported back on
