ab81b98c49 39758: revise 39704 for array and hash parameters; more POSIXBUITINS tweaks for 
export

39704 was commit 0f5e670, forgot to reference article number in that log.

"typeset -p" outputs "typeset" for array and hash parameters, even when
exported, because those types can be marked export but are never pushed
to the enviroment.

For POSIXBUILTINS, "export var" does not implicitly set $var, and its
export state is preserved when assigned (but not when explicitly unset).

b32d974000 39460: Don't import PS4 if running as root. 
There was an exploit in bash using SHELLOPTS to turn on xtrace,
however this can't happen in zsh, so this is simply a precaution.

c6c9f5daf2 34322: bug with interface to parsestr() etc. 
Was showing up in places like ${(e)...} where command substitution
could reallocate the token string, but actually there was never any
guarantee that the lexer wouldn't do that, so this was always
a bit iffy.

d067ebcacd 33876: etc.: Separate errors and keyboards interrupts 
Combination of 12 commits from interrupt_abort branch.

Basic strategy is to introduce bits to errflag and to set and
reset them separately.

Remove interrupt status on return to main keymap.

Turn off ERRFLAG_INT for always block.

Restore bit thereafter: we probably need a new variable in order
to allow user interrupts to be reset in the always block.

Add TRY_BLOCK_INTERRUPT

This works the same as TRY_BLOCK_ERROR, but for a SIGINT, too.

Ensure propagation of SIGINT from exited job.

If received by foreground job, shell uses ERRFLAG_INT, not
ERRFLAG_ERROR, to set the new state.

Reset errflag before precmd()

Add always block in _main_completion to fix ZLS_COLORS

Ensures we get the right state of $ZLS_COLORS at the end of _main_complete
even if there's an interrupt.  However, the "right state" is a bit messy
as it depends on styles.
