Eliminate catch(const char*)

I think we have to keep a few of them at least for 3.7

./cpp/src/Glacier2Lib/Application.cpp:    catch(const char* ex)
./cpp/src/Ice/Service.cpp:    catch(const char* msg)
./cpp/src/Ice/PluginManagerI.cpp:                catch(const char* msg)
./cpp/src/Ice/Application.cpp:    catch(const char* msg)
./cpp/src/Ice/Application.cpp:    catch(const char* msg)

Removing this could break applications that work fine with 3.7.1

I remove most of the occurrences just keep the ones mentioned above for compatibility. We can remove the rest for 3.8
