f6de8ec262 create_breapoint / explicit mode: Error out if there's garbage after the breakpoint location. 
If !PARSE_CONDITION_AND_THREAD, then ARG is just the location, nothing
else.  The fact that the describing comment of create_breakpoint
doesn't mention this just looks like an oversight of when extra_string
was added.  "parse_condition_and_thread" has been a misnomer ever
since extra_string was added -- better rename it avoid more confusion.
This makes it "parse_arg", as that'll remain stable even if/when more
explicit parameters are added.

d80ee84fe2 Change detach_breakpoints to take a ptid instead of a pid 
Before this change, detach_breakpoints would take a pid, and then
set inferior_ptid to a ptid that it constructs using pid_to_ptid (pid).
Unfortunately, this ptid is not necessarily valid.  Consider for
instance the case of ia64-hpux, where ttrace refuses a register-read
operation if the LWP is not provided.

This problems shows up when GDB is trying to handle fork events.
Assuming GDB is configured to follow the parent, GDB will try to
detach from the child. But before doing so, it needs to remove
all breakpoints inside that child.  On ia64, this involves reading
inferior (the child's) memory. And on ia64-hpux, reading memory
requires us to read the bsp and bspstore registers, in order to
determine where that memory is relative to the value of those
registers, and thus to determine which ttrace operation to use in
order to fetch that memory (see ia64_hpux_xfer_memory).

This patch therefore changes detach_breakpoints to take a ptid instead
of a pid, and then updates all callers.

One of the consequences of this patch is that it trips an assert
on GNU/Linux targets.  But this assert appears to have not actual
purpose, and is thus removed.

gdb/ChangeLog:

        * breakpoint.h (detach_breakpoints): pid parameter is now a ptid.
        * breakpoint.c (detach_breakpoints): Change pid parameter into
        a ptid.  Adjust code accordingly.
        * infrun.c (handle_inferior_event): Delete variable child_pid.
        Update call to detach_breakpoints to pass the child ptid for
        fork events.
        * linux-nat.c (linux_nat_iterate_watchpoint_lwps): Remove
        assert that inferior_ptid's lwp is zero.
        (linux_handle_extended_wait): Update call to detach_breakpoints.
        * inf-ttrace.c (inf_ttrace_follow_fork): Update call to
        detach_breakpoints.

956a9fb9fb improve Ada exception catchpoint MI notification 
This rewrites the code generating the Ada exception catchpoint hit
notification for both the GDB/MI case as well as the non-MI case,
by using the relevant ui_out_* functions to generate the output.
the MI notifications for Ada exception catchpoints now include
the stop reason, and the breakpoint "disp", much like other breakpoint
events do.  It also introduces a new field "exception-name" for
exception catchpoints (excluding "failed assertion catchpoints,
where we just want to know that it was a failed assertion).

gdb/ChangeLog:

        * breakpoint.h (bpdisp_text): Add declaration.
        * breakpoint.c (bpdisp_text): Make non-static.
