errors: use exit code 10 for parse errors Now that `ParseError`s raised while reading the config file has been converted into `ConfigError`s, the remaining parse errors should all be "input errors" (i.e. exit code 10), according to https://www.mercurial-scm.org/wiki/ErrorCategoriesPlan. Differential Revision: https://phab.mercurial-scm.org/D9332

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