Log Message:
Add a patch to deal with CVE-2021-35940.

An out-of-bounds array read in the apr_time_exp*() functions was
fixed in the Apache Portable Runtime 1.6.3 release (CVE-2017-12613).
The fix for this issue was not carried forward to the APR 1.7.x
branch, and hence version 1.7.0 regressed compared to 1.6.3 and is
vulnerable to the same issue.
