boost: 1.65.0 Update + Fixes
This commit updates the boost libraries to version 1.65.0 This new version brings two new libraries: - Boost.Stacktrace [1] -> Gather, store, copy and print backtraces, from Antony Polukhin. - Boost.PolyCollection [2] -> Fast containers of polymorphic objects, from Joaquín M López Muñoz. Fixes in this commit: - Boost.Python for Python 3.6 -> The dynamic library was not being compiled, resulting in an empty package. Fixed. - Boost.TypeErasure -> The dynamic library was not available to install. Fixed. - Boost.Serialization -> The wserialization dynamic library was being compiled but not available to install. Fixed. Extras: - This commit also contains the post-release fixes, which did not make it into the final release [3]. As always, more information about this release, can be found in [4].
