qemu: Bump to version 2.11.0

Use the latest QEMU release 2.11. Remove all patches that are no longer
required as they have been merged into the 2.11 releaese. One patch had
to be updated to apply to the 2.11 tree.

This also applies a linux user patch to avoid webkitgtk build hangs.

-I've tracked down what I think is a problem causing qemu-system-ppc
-to hang whilst booting images.
-
-I believe the decrementer timer stops receiving interrupts so
-tasks in our images hang indefinitely as the timer stopped. 
-
-It can be summed up with this line of debug:
-
-ppc_set_irq: 0x55b4e0d562f0 n_IRQ 8 level 1 => pending 00000100req 00000004
-
-It should normally read:
-
-ppc_set_irq: 0x55b4e0d562f0 n_IRQ 8 level 1 => pending 00000100req 00000002
-
-The question is why CPU_INTERRUPT_EXITTB ends up being set when the
-lines above this log message clearly sets CPU_INTERRUPT_HARD (via 
-cpu_interrupt() ).
-
-I note in cpu.h:
-
-    /* updates protected by BQL */
-    uint32_t interrupt_request;
-
-(for struct CPUState)
-
-The ppc code does "cs->interrupt_request |= CPU_INTERRUPT_EXITTB" in 5
-places, 3 in excp_helper.c and 2 in helper_regs.h. In all cases,  
-g_assert(qemu_mutex_iothread_locked()); fails. If I do something like:
-
-if (!qemu_mutex_iothread_locked()) {
-    qemu_mutex_lock_iothread();
-    cpu_interrupt(cs, CPU_INTERRUPT_EXITTB);
-    qemu_mutex_unlock_iothread();
-} else {
-    cpu_interrupt(cs, CPU_INTERRUPT_EXITTB);
-}
-
-in these call sites then I can no longer lock qemu up with my test
-case.
-
-I suspect the _HARD setting gets overwritten which stops the 
-decrementer interrupts being delivered.
