Bug:Boost: Use shlibs instead of header-only for call_stack::top_

This symbol is defined as a static member object inside of a boost detail header. When boost headers are used in a project that uses Boost in both the main binary as well as dlopen()'d shlibs, the top_ symbol gets duplicated and the metadata gets partitioned. We use the Boost shlib to unify both the main binary and the shlibs to use the same memory address for top_. This involves marking the templated object call_stack::top_ as "extern" and then declaring to Boost that we intend to use the shlibs.

+#   2. Checks for boost libraries in the dependency list
