  Log Message:
  -----------
  Replace boost::multi_index_container with tbb::concurrent_unordered_set in symtab_impl (#1544)

* Replace boost::multi_index_container with tbb::concurrent_unordered_set

There are now only two dimensions to each Module, so the multi_index
isn't needed. This also replaces the mutex with the intrinsic reader/
writer locks in TBB.

* Rename indexed_modules.hpp -> indexed_modules.h

* Add include guards

* add copyright

* Remove usage of'this' in fixSymModules
