[dwarf] Anonymous nested function causes SEGV during psymbol read

According to the DWARF3 standard, a function always has a name attribute
(Section 3.3 - Subroutine and Entry Point Entries).  The only exception
is when a DW_AT_abstract_origin attribute is provided, in which case
the name may be inherited from the referenced DIE.

The problem occured because our compiler generated a subprogram DIE
for a nested function where the name attribute was missing (and no
abstract-origin either).  Our code in add_partial_symbol is not
prepared to deal with the situation, and happily just tries  to compute
the length of the (NULL) function name.

This normally cannot happen, because there is already a guard in
scan_partial_symbols, where we (silently!) ignore anonymous dies,
including anonymous subprograms. Unfortunately, there is a flaw that
affects Ada and other languages that allow nested subprograms. For
nested subprograms, we do not go through scan_partial_symbols and
thus we are missing the name check.

This patch adds the name check in the nested subprogram case. It also
adds a complaint which is emitted during the psymtab->symtab conversion
phase.

gdb/ChangeLog:

        * dwarf2read.c (add_partial_subprogram): Make sure the subprogram
        DIE has a name before creating the associated partial symbol.
        (read_func_scope): Emit a complaint if the subprogram does not
        have a name or when we can't extract the subprogram PC bounds.

the purpose of the "list file1.txt:1" test.

Avoid switch to invalid ptid during Ada task switch.

This is to prevent an internal error during an Ada task switch. A task
switch is simply a thread switch under the hood. What we do is collect
the info from the Ada Task Control Block, deduce the associated thread
ptid, and then switch to that thread.  If the thread ptid computation
routine has not been implemented for the target, of if there is a bug,
then we end up computing a bogus ptid which GDB does not know about,

     Assertion `tp' failed.
    A problem internal to GDB has been detected,
    further debugging may prove unreliable.
    Quit this debugging session? (y or n)

When this happens, it's just nicer for the user to print an error
message, and cancel the task switch. After this patch is applied,
this is what we get:

    (gdb) task 1
    [New Thread 10250]
    Unable to compute thread ID for task 1.
    Cannot switch to this task.

        before doing the associated thread switch.

Requalify Ralf Corsepius' change as a "tiny change".

Ralf's copyright assignment does not cover GDB for the moment.
He only contributed one other change, in 2005, so this should be fine.

sim: rename bool argument to avoid stdbool clash

Including stdbool.h before hw-properties.h results in a build error due
to the hw_add_boolean_property function having an argument named "bool"
in its prototype.  The source file has already be renamed to not use
this ("boolean" instead), so match the header to the source.
