[Ada] Re-implement `info tasks' command using ui-out

This is in preparation for providing a GDB/MI equivalent of
the `info tasks' command.  The previous implementation was using
various printf commands to generate the command output, which
does not work at all if we want to use that same code to generate
the result for that new GDB/MI command.

This patch thus re-implements the `info tasks' command (with no
arguments) in a way that makes it GDB/MI friendly.

There is an additional hicup, which is the fact that the `info tasks'
command displays a completely different type of output when a task
ID is given. For instance:

    (gdb) info task 2
    Ada Task: 0x644d20
    Name: my_callee
    Thread: 0
    LWP: 0x5809
    Parent: 1 (main_task)
    Base Priority: 48
    State: Blocked in accept or select with terminate

The above output is better when in CLI mode, but really not
what we want when in GDB/MI mode. In GDB/MI mode, we want to
follow what the `-thread-info' command does when a task-id
is given as an argument, which is to produce the same table,
but with only one element/task in it.

For compatibility as well as practical reasons, we do not want
to change the output of the `info task TASKNO' command when in
CLI mode.  But it's easy to preserve this behavior while providing
the desirable output when in GDB/MI mode.  For this, the function
used to generated the `info tasks' output has been enhanced to take
an argument interpreted as a string. The CLI command knows to never
provide that argument, while the GDB/MI command will pass one if
provided by the user.

gdb/ChangeLog:

        * ada-tasks.c (print_ada_task_info): New function, merging
        short_task_info and info_tasks together.  Reimplement using
        ui-out instead of printing to stdout directly.  Move the code
        building and checking the task list here, instead of leaving it
        in info_tasks_command.
        (info_task): Move the code building and checking the task
        list here, instead of leaving it in info_tasks_command.
        (info_tasks_command): Delete code building and checking
        the task list - moved elsewhere.  Update calls to info_tasks
        and info_task.

One of the minor changes the switch caused is the introduction
of a space between the "current" column, and the task "ID"
column, which wasn't there before.  This matches what we do
in the "info threads" command, so I kept that change.  This
required an adjustment in the testsuite, however...

gdb/testsuite/ChangeLog:

        * gdb.ada/tasks.exp: Make the expected output for
        the `info tasks' tests more resilient to spacing
        changes.

[Ada] Remove `from_tty' parameter from ada-tasks.c:info_tasks

gdb/ChangeLog:

        * ada-tasks.c (info_tasks): Delete parameter `from_tty'.

[Ada] Adjust ada-tasks.c:ada_build_task_list

Originally, this function had a parameter called `warn_if_null'
which would trigger a message to be printed on stdout if the
program was found to not use Ada tasking.  It used one of the printf_
functions for that, which is wrong when considering the context of
GDB/MI interpreters.

So, this patch changes this function to stop printing the message,
and leaves that part to the callers instead.  It also changes the
semantics slightly to return the number of tasks found, rather than
a yes/no answer.  Not strictly needed, but simple enough to do, and
potentially useful later.

gdb/ChangeLog:

        * ada-lang.h (ada_build_task_list): Remove parameter
        `warn_if_null'.
        * ada-tasks.c (ada_build_task_list): Remove parameter
        `warn_if_null'.  Adjust implementation and documentation.
        (valid_task_id, ada_get_environment_task)
        iterate_over_live_ada_tasks): Adjust call to ada_build_task_list.
        (info_tasks_command): Adjust implementation.
        (task_command): Likewise.
        * ravenscar-thread.c (ravenscar_find_new_threads): Fix call
        to ada_build_task_list.

[Ada] Store the Ada task list in per-inferior data

Instead of storing "the" Ada task list using a static global
in ada-tasks, this patch stores that information inside
per-inferior data.

We also add in the per-inferior data the location and type of
data used in the runtime to store that task list.  Previously,
this information was saved as a static variable in one of the
functions, but this approach has the major flaw that it does
not handle multi-inferior debugging.

[Ada] Make the ATCB type info program-space-specific

This module caches the type description of various elements of
the Ada Task Control Block (ATCB). This cache was implemented
as static globals, which is wrong in the case where we have
multiple inferiors. This change cleans things up a bit by moving
some of these static globals to a per-program-space area.

gdb/ChangeLog:

        * ada-tasks.c: #include "progspace.h" and "objfiles.h".
        (atcb_type, atcb_common_type, atcb_ll_type, atcb_call_type)
        (atcb_fieldno): Delete these static globals.
        (struct ada_tasks_pspace_data): New struct.
        (ada_tasks_pspace_data_handle): New static global.
        (get_ada_tasks_pspace_data): New function.
        (ada_tasks_invalidate_pspace_data): New function.
        (get_tcb_types_info, ptid_from_atcb_common, read_atcb)
        (read_known_tasks_list, ada_new_objfile_observer): Adjust.
        (_initialize_tasks): Create this module's per-progspace
        data handle.

[Ada] Rename struct tcb_fieldnos into atcb_fieldnos.

`atcb' is clearer than `tcb', as it stands for Ada Task Control
Block. This is also consistent with the rest of the code, which
uses atcb...

        * ada-tasks.c (struct atcb_fieldnos): Renames struct tcb_fieldnos.
