  char: move backends' io watch tag to CharDriverState

All the backends implement an io watcher tag for callbacks.  Move it to
CharDriverState from each backend's struct to make accessing the tag from
backend-neutral functions easier.

This will be used later to cancel a callback on chardev detach from a
frontend.

  char: remove watch callback on chardev detach from frontend

If a frontend device releases the chardev (via unplug), the chr handlers
are set to NULL via qdev's exit callbacks invoking
qemu_chr_add_handlers().  If the chardev had a pending operation, a
callback will be invoked, which will try to access data in the
just-released frontend, causing a segfault.

Ensure the callbacks are disabled when frontends release chardevs.

This was seen when a virtio-serial port was unplugged when heavy
guest->host IO was in progress (causing a callback to be registered).
In the window in which the throttling was active, unplugging ports
caused a qemu segfault.

  -----------
  target-i386: Set model=6 on qemu64 & qemu32 CPU models

There's no Intel CPU with family=6,model=2, and Linux and Windows guests
disable SEP when seeing that combination due to Pentium Pro erratum #82.

In addition to just having SEP ignored by guests, Skype (and maybe other
applications) runs sysenter directly without passing through ntdll on
Windows, and crashes because Windows ignored the SEP CPUID bit.

So, having model > 2 is a better default on qemu64 and qemu32 for two
reasons: making SEP really available for guests, and avoiding crashing
applications that work on bare metal.

model=3 would fix the problem, but it causes CPU enumeration problems
for Windows guests[1]. So let's set model=6, that matches "Athlon
(PM core)" on AMD and "P2 with on-die L2 cache" on Intel and it allows
Windows to use all CPUs as well as fixing sysenter.

  cpu: Move cpu_copy() into linux-user

It is only used there and is deemed very fragile if not incorrect in its
current memcpy() form. Moving it into linux-user will allow to move
parts into target_cpu.h headers and only copy what the ABI mandates.
