Fix some polling issues:

 - Don't background-poll disabled TAPs ... this was just a bug
   waiting to happen.  (And then it happened!)

 - Don't fail command line polls of disabled taps; that's not any
   kind of error, it's just that you can't do much.  But do show
   that tap-disabled status.

 - Spell "continuous" correctly in the variable name.  ;)

Not resolved by this patch:  the need for an interlock whereby
other code (like the JTAG layer) can block all other access to
the JTAG layer, e.g. while enabling or disabling TAPs.  And
that interlock needs to be timer-safe...

reference the related "$target_name curstate" method.

Update "poll" output to report whether background polling

Also fix a small typo; PC's have "complementary" tools.
Some have also "complimentary" ones; but not all.

- Don't let disabled TAPs be set as the current target

 - Improve "targets" output:
    * Remove undesirable "chain position" number; we discourage using them
    * TAP and Target column updates:
       + make them long enough for current usage
       + improve labels, removing guesswork
       + "TapName" label patches scan_chain output
    * Highlight the "current" target
    * Display "tap disabled" as a new pseudo-state
    * Update docs accordingly

git-svn-id: svn://svn.berlios.de/openocd/trunk@2107 b42882b7-edfa-0310-969c-e2dbd0fdcd60

Let disabled targets be ignored during normal operation:

 - In target_examine(), ignore disabled TAPs

 - Reset handling must not poke at them either:
     * fail $target_name arp_* operations on disabled TAPs
     * in startup.tcl, don't even issue the arp_* wait ops 

ZW: removed superfluous braces from the patch to target.c.
