Issue #29188: Support glibc 2.24 on Linux: don't use getentropy() function but
read from /dev/urandom to get random bytes, for example in os.urandom().  On
Linux, getentropy() is implemented which getrandom() is blocking mode, whereas
os.urandom() should not block.

In urllib, suffixes in no_proxy environment variable with
leading dots could match related hostnames again (e.g. .b.c matches a.b.c).
