> When failing to load libs we do not put out the last error msg e.g.

>     if (!m_LibHandler)

>     }
>     return AXIS_SUCCESS;

> There are already methods in Platform specifics to get the last error msg and these were
used in Axis Transport2. I think they are also used in other lib load failure situations.
We must change all lib load fails to give as much info as possible.
