commit 435f53a7d750fa27c9a73de4716a62c9363b5a91

    fix memory double-free in module_cache
    
    The kmodule.stp test case could evoke a double-free of module-info
    structs, since these were shared pointers, and not managed by GC.
    Oh yeah, what GC, in the year 2010.
    
    * dwflpp.cxx (dwflpp dtor): Don't delete shared mod_info ptr.
      (module_cache dtor): New function.
    * dwflpp.h: Declare.
    * tapsets.cxx (delete_session_module_cache): New function.
      (several::build_no_more): Call it.
      (dwarf_build_no_more): Use delete_map<> template.
