[RFA] Add observer notification in normal_stop

[Joel Brobecker <brobecker@gnat.com>]

Hello,

I am currently writing a regression test for observer.c, which will live
in testsuite/gdb.gdb. It's using a mechanism similar to xfullpath.exp.
But in order for the test to function, observer.o needs to be linked in.
This wasn't the case up to now, because there is currently no code using
it.

This patch is adding a call to observer_notify_normal_stop() inside
normal_stop. This notification will be useful later, when the latest
version of ada-task.c (from ACT's repository, accessible from
libre.act-europe.fr BTW) is contributed. In the meantime, the overhead
is really minimal and it allows us to test observer.c by debugging gdb.

2003-03-17  J. Brobecker  <brobecker@gnat.com>

        * infrun.c (observer.h): Add #include.
        (normal_stop): Add call to observer_notify_normal_stop.
        * Makefile.in (infrun.o): Add dependency on observer.h.

Ok to apply?
