[rfc] Print solib events in mi-mode

[Kris Warkentin]

What do you think of something like this?  When stop-on-solib-events is set,
this will print the reason as being a shared-lib-event.

Our Eclipse team wants to be able to set breakpoints in shared libraries
that aren't loaded yet.  If they get notification of shlib-events, then they
can re-examine the list of loaded libraries and set any breakpoints that
have been enabled in the project's libs.

cheers,

Kris
