5b37825d84 The remote stub can implement monitor commands which are not 
known by gdb. Such monitor commands can take a long time
to execute. An example of this is the "leak_search" monitor
command implemented in the Valgrind gdbserver.

Currently, gdb will timeout on such a monitor command.
The remote stub however will continue to execute the
command and send the output later. Gdb and the remote
stub can then be desynchronised : gdb sends a packet,
and the reply read from the stub is a previous packet.

The change committed uses getpkt_sane to detect a timeout.
In this case, it continues the loop.
A QUIT; is inserted in the loop to allow the user
to stop handling the current command. possibly
still creating a desynchronisation between gdb and the stub
but that will be upon user request.

f7e44f6574 GDB/MI: crash printing "_task" (Ada) argument 
In GDB/MI mode, trying to print the arguments of the frame corresponding
to the body of a task ("-stack-list-arguments 1") causes the debugger to
crash.

This is because the compiler adds an implicit argument to that task body
called "_task". mi/mi-cmd-stack.c:list_args_or_locals, which is
responsible for printing the value of our arguments, finds that our
"_task" symbol is an argument, and thus tries to fing the non-argument
equivalent:

              if (SYMBOL_IS_ARGUMENT (sym))
                sym2 = lookup_symbol (SYMBOL_NATURAL_NAME (sym),
                                      block, VAR_DOMAIN,
                                      (int *) NULL);

Unfortunately, it tries using the natural name, which doesn't always
work for Ada parameters, in particular those who are internally-
generated. In our case, The "_task" parameter's natural name is
"<_task>", and that symbol does not exist.  So sym2 is NULL, thus
causing the crash a little later on when trying to dereference it.
We should be using the symbol linkage name in this case, the same
way iterate_over_block_arg_vars already does.

gdb/ChangeLog:

        * mi/mi-cmd-stack.c (list_args_or_locals): For argument symbols,
        use SYMBOL_LINKAGE_NAME to find the corresponding non-argument
        symbol.  Add assertion that sym2 is never NULL.

        * gdb.ada/mi_task_arg: New testcase.
