Bring iso3166 file in sync with HEAD

MFC of recent updates on the ISO3166 file:

r223633
- Remove AN again now that tzdata2011h has been imported.

r222094
- Put AN back after finding out that tzsetup(1) will complain that
  it doesn't exist. It will be removed again once the tzdata distribution
  files have been updated with the replacements for AN.

r222014
- Revert change to "MF" I made in r189767.  I bet that at the time of r189767
  I checked with http://www.iso.org/iso/country_codes/iso_3166_code_lists.htm
  and "MF" was officially spelled in English as "Saint Martin" there, but now
  that "SX" exists (for "Sint Maarten (Dutch part)") (nice official "English"
  spelling!) they seem to have added a "(French part)" suffix to "MF".  Since
  this is also in line with Newsletter VI-1 (2007-09-21), catch up.

r222011
- ISO3166: Update for newsletters VI-7 and VI-8 from 2010
  - Name change for SH
  - BQ, CW, and SX replace AN
