Bug 2405

Processing of ORB options, both command line arguments passed to ORB_init() and
Resource Factory options from Service Config files do minimal error checking of
option arguments.  For example, binary and numeric arguments are typically
parsed by ACE_OS::atoi().  This allows bogus arguments (and typos like
-ORBDebugLevel 5-ORB...) to pass undiagnosed.

Even using ACE_OS::strtol() would be an improvement, as its "ep" argument can be
used to detect whether the entire argument was processed/converted.

It's been suggested that we may want to do this in the context of larger option
processing refactors that have been discussed lately (supporting ORB_init()'s
-ORBoptions in service config files, supporting multiple service configurator
instances, etc).
