Title:
  Need ASCII regex

Status in Zorba - The XQuery Processor:
  Fix Released

Bug description:
  As discussed on the zorba-coders mailing list, in order to build Zorba
  without ICU, there needs to be a ASCII regular expression library to
  take the place of ICU.  The existing code in
  zorbatypes/regex_ascii.h/.cpp needs to be wrapped by the existing
  regex class for an alternate implementation when ZORBA_NO_UNICODE=ON,
  e.g.:

  #ifndef ZORBA_NO_UNICODE
  // existing regex class
  #else
  // new regex class backed by regex_ascii
  #endif

  You probably also need to provide an alternate implementation of
  convert_xquery_re() (in regex.h/.cpp) that currently converts an
  XQuery regular expression into an ICU regular expression.  If the
  existing regex_ascii regular expressions exactly match XQuery regular
  expressions, then the alternate implementation of convert_xquery_re()
  can simply copy xq_re to lib_re as-is.
