[8u] RFR: 8226607: Inconsistent info between pcsclite.md and MUSCLE headers

[Severin Gehwolf]

Hi,

Could I get a review of this follow-up fix for an 8u backport (JDK-
8218780)? This follow-up re-adds a COPYING file to the MUSCLE pcsc
library header files removed by the JDK-8218780 backport. The patch
differs from the version in JDK 11 since there is no pcsclite.md file
in OpenJDK 8u.

Bug: https://bugs.openjdk.java.net/browse/JDK-8226607
webrev: http://cr.openjdk.java.net/~sgehwolf/webrevs/JDK-8226607/jdk8/01/webrev/
JDK 11u changeset: https://hg.openjdk.java.net/jdk-updates/jdk11u-dev/rev/9e304e99cbb2

I intend to push this fix together with JDK-8218780 once it passed
review and got approved.

Thoughts?

Thanks,
Severin
