These exceptions don't require checking a server status.

Thanks Nick Pope for the review.

Fixed #30412 -- Fixed crash when adding check constraints with OR'ed condition on Oracle and SQLite.

Fixed #30408 -- Fixed crash when adding check constraints with LIKE operator on Oracle and PostgreSQL.

The LIKE operator wildcard generated for contains, startswith, endswith and
their case-insensitive variant lookups was conflicting with parameter
interpolation on CREATE constraint statement execution.

Ideally we'd delegate parameters interpolation in DDL statements on backends
that support it but that would require backward incompatible changes to the
Index and Constraint SQL generating methods.

Thanks David Sanders for the report.

Refs #30323 -- Prevented crash of autoreloader when get_resolver().urlconf_module raising an exception.

Follow up to 253adc2b.

Regression in 181fb601.

Fixed #30361 -- Increased the default timeout of watchman client to 5 seconds and made it customizable.

Made the default timeout of watchman client customizable via
DJANGO_WATCHMAN_TIMEOUT environment variable.

Thanks to Jon on Stack Overflow for reporting the issue.

Fixed #30388 -- Made inspectdb generate OneToOneFields rather than ForeignKey(unique/primary_key=True).

Thanks Carlton Gibson for the review.

When on MacOS High Sierra or below (<=10.13) it could be that a HFS+
filesystem is used. HFS+ has a time resolution of only one second
which can be too low for some of the tests.
