v1.8.1

Small bugfix release of libunwind 1.8.

One of the functional changes is that the testsuite is now installed with a make install, which may affect downstream packagers. By default these executables are installed in ${libexecdir}/libunwind where ${libexecdir} defaults to ${prefix}/libexec, but all this can be set explicitly though arguments to configure.

• Fix issue #713 by @cshung in #717
• Add do-release script by @bregma in #725
• Backport dotnet-runtime fixes to the 1.8 branch by @bregma in #726
• [v1.8] Make tests installable by @bregma in #722
