Part revert #22 to undo memory fault (re: b7932e87)

Browse source 
The fix in sh/xec.c, which was backported from the ksh 93v- beta to
delay the actual removal of a running function that unsets itself,
caused a segfault in the variables.sh regression tests (see #23).

src/cmd/ksh93/sh/xec.c:
- Comment out the backported code pending a correct fix for #21.
  Now both types of functions silently fail to unset themselves
  (unless they're discipline functions).

src/cmd/ksh93/tests/functions.sh:
- Disable regression tests checking that the function was actually
  unset, pending a correct fix for #21.

Resolves: #23
Reopens: #21

- A POSIX function that unsets itself while it is running no longer causes
a segmentation fault.
- `unset -f` no longer silently fails when a KornShell style function tries
to unset itself while it is running. The function will now be unset once
it has finished running.

- Passing the '-d' flag to the read builtin will no longer cause the '-r'
