* breakpoint.c (update_watchpoint): Change between software and
hardware watchpoint for all kinds of watchpoints, not just
read/write ones. Determine b->exact value here instead of
in watch_command_1. Error out if there are not enough resources
for a read or access hardware watchpoint.
(watch_command_1): Remove logic of checking whether there are
enough resources available, since update_watchpoint will do that
work now. Don't set b->exact here. Catch exceptions thrown by
update_watchpoint and delete the watchpoint.

has a breakpoint number assigned to it.

New functions.

of unwinders.
It turns out that this change is not correct, and it causes a crash
on sparc-solaris while trying to load ld.so. This is because the
memory is actually still referenced after elf_symtab_read completes.

A change we are making in the compiler to help preserve useful
types when using -feliminate-unused-debug-types exposed a small
hole in our value-printing code.
One example of the problem happens when trying to print a slice
of an array pointer. If the variable is defined as a pointer to
the typedef of an array, then we fail to print the slice, like so:
(gdb) p arr_ptr(1..2)
cannot take slice of non-array

* ada-lang.c (ada_is_simple_array_type, ada_value_slice_from_ptr)
(ada_value_slice, empty_array, to_fixed_array_type): Deal with
typedefs.
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).
