Attn: Remove --defaultbreakpoint add --defaultti

In order to support breakpoint handling and TI handling on systems that
did not support the get TI info interface the --defaultbreakpoint
configuration option was added. This switch is no longer needed and
breakpoint handling is now the default action for available but invalid
TI info data. A new option --defaultti was added to force handling of
TI's when TI info is available but not valid.
