USA-only datachecks

[yakra]

• [x] C++: Rather than have each datacheck function check whether country == USA, check once then call all the functions.
• If I really wanna get jiggy wit it, no need to dereference a bunch of pointers and then iterate thru & compare up to 3 chars of the country string when we know beforehand whether a route's system is in the USA, and can set a bool USA_flag...
  • [x] C++: construct in Route::read_wpt; no need to recalculate for every point (easier, slightly less efficient)
  • [x] C++: pass to Route::read_wpt from main & ReadWptThread; no need to recalculate for every route (more involved, more efficient)
  • [x] Python: ...in the outermost datacheck loop
• [x] Resurrect US_BANNER (as US_LETTER?)

  for rg in `ls | grep -v _`; do grep -sv '^+' $rg/*/*.wpt | cut -f1 -d' ' | egrep ':\*?US[0-9]+[AB][/_(]|:\*?US[0-9]+[AB]$'; done

  • [x] Python
  • [x] C++
  • [x] descriptor table
  • [x] datacheck_always_error
  • [x] wptedit
  • [x] syserr.php
  • [x] datacheck.php
  • [x] add "letter " here
• [x] INTERSTATE_NO_HYPHEN does not account for leading *
