Subject: SWAT-352: when loading lleventhost, call apr_dso_error() function. In
addition to its usual apr_sterror() function, APR defines a special function
specifically for errors relating to the apr_dso_*() functions. Introduce
ll_apr_warn_status() and ll_apr_assert_status() overloads accepting
apr_dso_handle_t* to call apr_dso_error() as well as apr_strerror() and log
its output. Use new ll_apr_warn_status() in
LLAppViewer::loadEventHostModule() for apr_dso_load() and apr_dso_sym()
calls. Instead of shorthand ll_apr_assert_status(), use with
llassert_always() so check is still performed even in Release build. Add more
lleventhost-related debugging output, e.g. full pathname of the DLL. On Mac
and Linux, call 'file' command to report nature of the DLL too.
