This 2.13.1 release of LTTng-UST is a bugfix-only release for various
shortcomings that were identified in the 2.13.0 release.

A few key highlights: the C++ support for building probe providers has
been improved, async-signal-safety of the close wrapper has been fixed,
pthread cancelstate in nested use scenarios is now properly handled.
