Bug fixes from pdksh-unstable-5.2.13.4, including "official" versions of

some that we had already fixed locally.
 o typeset -f FUNC doesn't print follows command (and expression) substitutions.
 o when re-allocating memory, too much may be copied from old memory.
 o set -o printed some options sans names.
 o emacs mode: <esc>. in very fist command causes core dump.
 o pdksh dumps core after a cd command.
 o typeset -i reports on array elements that have no value
   (at&t ksh reports on array base name - no index).
 o ulimit -ctn unlimittttted kills shell (resource exceeded).
 o ". /dev/null" says access denied.
 o flag field in aliases incorrectly changed (all flags set instead of
   clearing ISSET) in exec.c(flushcom).
 o ${#array[*]} prints largest index instead of number of (set) elements
   in an array (ksh88 does the former).
 o sys_siglist[] doesn't always have NSIG non-null entries...
