With Open MPI 5.0, the decision was made to stop building 3rd-party packages, such as Libevent, HWLOC, PMIx, and PRRTE as MCA components and instead 1) start relying on external libraries whenever possible and 2) Open MPI builds the 3rd party libraries (if needed) as independent libraries, rather than linked into libopen-pal. This patch moves libevent from an MCA framework to a stand-alone library built outside of OPAL. A wrapper in opal/util is provided to minimize the unnecessary changes in the rest of the code. When using the internal Libevent, it will be installed as a stand-alone libevent.a, instead of bundled in OPAL. Any pre-installed version of Libevent at or after 2.0.21 is preferred over the internal version. Signed-off-by: Brian Barrett <bbarrett@amazon.com>
