  Changed paths:
    M dyninstAPI/h/BPatch_binaryEdit.h
    M dyninstAPI/src/BPatch_binaryEdit.C
    M proccontrol/src/int_thread_db.C

  Log Message:
  -----------
  Attempts to fix legacy test failures in Dyninst test suite (#549)

* In binary rewriting, when Dyninst needs to load a library,
    it does not check whether this library has been loaded before or not.
    Dyninst will create multiple binaryEdit objects for one library, which can cause inconsistent states between these objects.

    This fix adds a map to BPatch_binaryEdit to make sure each library is only loaded once.

* Fix pc_tls failures in dyamically linked binaries.
    The root cause is a broken library name matching code.
    Just should boost:filesystem::path to deal with file paths.

Closes #549
