[RFR] [7u] jdk7u271-b01

[Andrew Hughes]

Here are the changes for the jdk7u repository for the July 2020 security
update.  As well as the security fixes from jdk8u262-b10, I also
included a few relevant backports from earlier in the 8u262 cycle, along
with a number of outstanding bundled library updates which have
apparently been in the proprietary Oracle 7u fork for some time.

Webrev: https://cr.openjdk.java.net/~andrew/openjdk7/20200714/

Changes:
  - JDK-8028431: NullPointerException in DerValue.equals(DerValue)

sun.security.util.DerInputStream.getUnalignedBitString()

  - JDK-8244548: JDK 8u: sun.misc.Version.jdkUpdateVersion() returns

Assuming our testing then goes ok, we'll add the tag jdk7u271-ga and
make the release.
