global: use pycompat.xrange()

On Python 3, our module importer automatically rewrites xrange()
to pycompat.xrange().

We want to move away from the custom importer on Python 3.

This commit converts all instances of xrange() to use
pycompat.xrange().

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
