Watchdog: disable watchdog timer when hard-rebooting a guest.
This commit causes the watchdog timer to be reset when a guest is
hard-rebooted.
The failure case previously was as follows:
(a) guest boots, watchdog is enabled
(b) guest does a reset eg:
echo 'b' > /proc/sysrq-trigger
(note that an ordinary /sbin/reboot wouldn't hit this case
since as the watchdog daemon is shut down, the daemon would
properly disable the watchdog device)
(c) the reboot takes longer than the remaining time on the
watchdog
(d) the watchdog therefore fires during the reboot
(e) probably the VM would just reboot again at this point which
is pretty benign, but it could depend on the action that the
user had selected for the watchdog
Now we use the qdev reset function to register a reset handler
which disables the timer. Note the handler is called _either_
just after init _or_ when the guest reboots.
In the i6300esb case there is a small refactoring of the code so
that the device's internal state is now fully restored to defaults
on a reboot.

exec: introduce endianness swapped mmio
The way we're currently modeling mmio is too simplified. We assume that
every device has the same endianness as the target CPU. In reality,
most devices are little endian (all PCI and ISA ones I'm aware of). Some
are big endian (special system devices) and a very little fraction is
target native endian (fw_cfg).
So instead of assuming every device to be native endianness, let's move
to a model where the device tells us which endianness it's in.
That way we can compile the devices only once and get rid of all the ugly
swap will be done by the underlying layer.
For the same of readability, this patch only introduces the helper framework
but doesn't allow the registering code to set its endianness yet.

linux-user: fix memory leaks with NPTL emulation
Running programs that create large numbers of threads, such as this
snippet from libstdc++'s pthread7-rope.cc:
const int max_thread_count = 4;
const int max_loop_count = 10000;
...
for (int j = 0; j < max_loop_count; j++)
{
...
for (int i = 0; i < max_thread_count; i++)
pthread_create (&tid[i], NULL, thread_main, 0);
for (int i = 0; i < max_thread_count; i++)
pthread_join (tid[i], NULL);
}
in user-mode emulation will quickly run out of memory. This is caused
by a failure to free memory in do_syscall prior to thread exit:
/* TODO: Free CPU state. */
pthread_exit(NULL);
The first step in fixing this is to make all TaskStates used by QEMU
dynamically allocated. The TaskState used by the initial thread was
not, as it was allocated on main's stack. So fix that, free the
cpu_env, free the TaskState, and we're home free, right?
Not exactly. When we create a thread, we do:
ts = qemu_mallocz(sizeof(TaskState) + NEW_STACK_SIZE);
...
new_stack = ts->stack;
...
ret = pthread_attr_setstack(&attr, new_stack, NEW_STACK_SIZE);
If we blindly free the TaskState, then, we yank the current (host)
thread's stack out from underneath it while it still has things to do,
like calling pthread_exit. That causes problems, as you might expect.
The solution adopted here is to let the C library allocate the thread's
stack (so the C library can properly clean it up at pthread_exit) and
provide a hint that we want NEW_STACK_SIZE bytes of stack.
With those two changes, we're done, right? Well, almost. You see,
we're creating all these host threads and their parent threads never
bother to check that their children are finished. There's no good place
for the parent threads to do so. Therefore, we need to create the
threads in a detached state so the parent thread doesn't have to call
pthread_join on the child to release the child's resources; the child
does so automatically.
With those three major changes, we can comfortably run programs like the
above without exhausting memory. We do need to delete 'stack' from the
TaskState structure.
