qt5base-lts/util/local_database/cldr2qtimezone.py
Edward Welbourne 08cfd02312 Use python more competently in CLDR/qLocaleXML scripts 
Make the python2 dependency explicit (sooner or later, python3 shall
be the default /bin/env python), make time-zone script executable (it
had a shebang).  Use triple-quoted strings, or single quotes, to avoid
extra backslashes, remove some simply spurious backslashes.  Use
generators rather than map or filter with lambdas and iterate rather
than duplicating code.  Clarify some comments.

Regenerated headers: this upates the date of generation, cuts back a
double-blank-line to single and skips a spurious trailing
comma-newline on an array's data.
