ada-tasks.c: handle known tasks maintained by a simply-linked list.
The mapping between Ada tasks, and the underlying threads is
normally maintained by the GNAT runtime under the known_tasks
array. For performance reasons, this array is just a static
array with 10_000 entries in it. However, this is not very
practical in certain environments where memory is limited.
For those environments, the runtime has been enhanced to use
an alternate scheme with a linked list.
This change enhances the Ada tasking support to recognize this
situation and use the correct way of reading the tasks info
based on the the situation.

[mach-o] get rid of current_oso global
This current_oso global was used to store the OSO's symbol table
in order to relocate common symbols. But it is also making the
assumption that all sections are going to be immediately relocated
as macho_add_oso_symfile does:
- Initialize the current_oso
- Use it through symbol_file_add_from_bfd
- Reset the current_oso (to all fields NULL)
What actually happens is that the .debug_frame section gets read
lazily, and thus relocated at a later time. This relocation causes
current_oso.symbol_table to be initialized (see macho_symfile_relocate)
again. And this eventually causes to trip the...
gdb_assert (current_oso.symbol_table == NULL);
...assertion to fail because the symbol_table was never free'ed.
To be complete, this happens because macho_symfile_relocate was
called outside of macho_add_oso_symfile's control, where the
set-global/use/unset-global dance happens.
But it looks like keeping this global around is not necessary, as
this symbol table is only used to relocate the common symbols.
We can do that prior to relocating the rest of the symbols.

* machoread.c (struct macho_oso_data): Delete.

[Darwin] Do not crash (failed assertion) after PT_KILL ptrace error
It might not be a debugger bug that caused the PT_KILL ptrace operation
to fail. So emit a warning instead, and try to continue.
This patch also tries to handle the case where ptrace return -1,
but left errno set to zero. According to the ptrace man page,
it is possible for some ptrace operations to return -1 in non-error
situations, and to detect those situations, it explains that errno
should be set prior to calling ptrace, and then checked again after.

Set errno to zero before calling ptrace. If ptrace returns
-1 and errno is zero, then change then return zero.

Darwin/detach: Do not resume inferior after ptrace detach
When trying to detach from an inferior that we start from the debugger,
GDB prints the following warning:
(gdb) detach
Detaching from program: /[...]/foo, process 74593
warning: Mach error at "/[...]/darwin-nat.c:445" in function "darwin_resume_inferior": (os/kern) failure (0x5)
The warning comes from the following code in darwin_detach:
darwin_resume_inferior (inf);
This is because the process has already been resumed by the
PT_DETACH ptrace operation that has just been performed.
On the other hand, when trying to detach from an inferior that
was started outside of debugger control (thus after having attached
the debugger to that inferior), things go smoothly. That's because
we don't use ptrace to control the process in that case, and so
the resume is perfectly justified.
This patch makes sure that we resume the inferior during the detach
only when we're NOT using ptrace.

crash when printing type of tagged type
If the debugging info is incorrect or incomplete, printing the
type description of a variable that's a variant tagged type can
trigger a crash. The crash comes from us trying print a NULL
string which was supposed to be the parent type name.
We observed this behavior on bareboard targets where a-tags is
not always linked in, as is the case for native platforms, for
instance. Coupled with -feliminate-unused-debug-types, this leads
to GDB being unable to find type ada__tags__type_specific_data,
without which printing the type description above cannot be done
acurately. There is an easy workaround for this limitation,
which is to compile at least 1 unit with
-fno-eliminate-unused-debug-types, but GDB should also be made
resilient to this situation.

Fix printing address of packed array

Fix ada array bounds display
Array bounds were not correctly displayed when the SHOW parameter of

type of situation, where we have a declaration as follow:
Anon_Array_Int_Obj : array (1..10) of Integer := (others => 8);
In GDB/MI mode, trying to print the type info for our array object
yields:
(gdb) -var-create ai 0 Anon_Array_Int_Obj
(gdb) -var-info-type ai
^done,type="array (...) of integer"
The actual bounds are missing. Contrast this with what happens
when in GDB/CLI mode:
(gdb) ptype Anon_Array_Int_Obj
type = array (1 .. 10) of integer

variables whose type is a typedef to an array pointer
If we declare a type as being an access to array type, and then
declare a variable of that type, for instance:
type Some_Array is array [...];
type Array_Access is access all Some_Array;
Table : Array_Access := [...];
The variable "Table" may be defined in the debugging information
as being a typedef to the array pointer type. In the past, it was
defined directly as the array pointer type, but this has been changed
to make sure that the typedef type gets used.
If the typedef type wasn't used, it would allow the compiler to stop
emitting that typedef type when compiling with
-feliminate-unused-debug-types. The removal of this typedef would
be a problem, because GDB relies on the typedef to create symbols
for pointer types, and without it, we would no longer be able to
do "ptype array_access".
This patch helps prevent incorrect output or even crashes when that
extra typedef layer is used.
The testing is already mostly covered by arrayptr.exp, but I still
added a 'ptype' test, just for good measure.
