libcap-2.67

[Bruce Dubbs]

New minor version.

[Xi Ruoyao]

• Replace use of fgrep with grep -F (POSIX grep flags preferred by GNU grep) - patch from David Seifert.
• Added SPDX identifiers to License file(s). Hopefully this will help the various robots out there correctly identify the longstanding licenses for libcap and friends. (Bug: 216609 reported by Günther Noack)
• Started down the rabbit hole of trying to address (Bug: 216610 reported by Günther Noack on behalf of Michael Stapelberg)
• The basic issue is how to link C code with Go psx without using CGo. This is all a low level hackery. If you are interested, browse the source.
• Correct for bad whatis entries in man pages (this was throwing a Debian build test, detail)
• Also reviewed man pages and addressed cross linkage issues (Bug: 216585)
• Cleaned up some README.md files (made a github mirror now just so I can automatically render them).
• Changed meaning of DYNAMIC=no builds.
• This now builds everything with static linking except for libc. The reason for this exception is explained in the commit message.
• Inserted demonstration exploit code in capso.so to support article.
