Commit 1b71f7c14f moved MODULE_INIT_QOM to
way before MODULE_INIT_MACHINE, thereby breaking assumptions made in
spice-core.c which registered both a type initializer and a machine
intializer.
This fix removes the type registration, and replaces it with calling
qemu_spice_init in vl.c after command line parsing (second pass) is
done, and after timers are armed, required by spice server.

This patch fixes warnings reported by splint:
For variables which are packed in a single bit, a signed data type
like 'int' does not make much sense.
There is no obvious reason why the two values should be packed,
so I removed the packing and changed the data type to bool

next_tb is the numeric value of a tcg target (= QEMU host) address.
Using tcg_target_ulong instead of unsigned long shows this and makes
the code portable for hosts with an unusual size of long (w64).
The type cast '(long)(next_tb & ~3)' was not needed (casting
unsigned long to long does not change the bits, and nor does
casting long to pointer for most (= all non w64) hosts.
It is removed here.
Macro or function tcg_qemu_tb_exec is used to set next_tb.
The function also returns next_tb. Therefore tcg_qemu_tb_exec
must return a tcg_target_ulong.

The pxa2xx I2C controller can have its registers at an arbitrary offset
within the MemoryRegion it creates. We use this to create two controllers,
one which covers a region of size 0x10000 with registers starting at an
offset 0x1600 into that region, and a second one which covers a region
of size just 0x100 with the registers starting at the base of the region.
The implementation of this offsetting uses two qdev properties, "offset"
(which sets the offset which must be subtracted from the address to
get the offset into the actual register bank) and "size", which is the
size of the MemoryRegion. We were actually using "offset" for two
purposes: firstly the required one of handling the registers not being
at the base of the MemoryRegion, and secondly as a workaround for a
deficiency of QEMU. Until commit 5312bd8b3, if a MemoryRegion was mapped
at a non-page boundary, the address passed into the read and write
functions would be the offset from the start of the page, not the
offset from the start of the MemoryRegion. So when calculating the value
to set the "offset" qdev property we included a rounding to a page
boundary.
Following commit 5312bd8b3 MemoryRegion read/write functions are now
correctly passed the offset from the base of the region, and our
workaround now means we're subtracting too much from addresses, resulting
in warnings like "pxa2xx_i2c_read: Bad register 0xffffff90".
The fix for this is simply to remove the rounding to a page boundary;
this allows us to slightly simplify the expression since
base - (base & (~region_size)) == base & region_size
The qdev property "offset" itself must remain because it is still
performing its primary job of handling register banks not being at
the base of the MemoryRegion.

Pxa2xx LCD controller is intended to work with 32-bit bus and it has no knowledge
of system's physical address size, so it should not use target_phys_addr_t in it's
state. Convert three variables in DMAChannel state from target_phys_addr_t to uint32_t,
use VMSTATE_UINT32 instead of VMSTATE_UINTTL for these variables.
We can do this safely because:
1) pxa2xx has 32-bit physical address;
2) rest of the code in file never assumes converted variables to have any size
different from uint32_t;
3) we shouldn't have used VMSTATE_UINTTL in the first place because this macro
is for target_ulong type (which can be different from target_phys_addr_t).

The migrate command is one of those commands where HMP and QMP completely
mix up together. This made the conversion to the QAPI (which separates the
command into QMP and HMP parts) a bit difficult.
The first important change to be noticed is that this commit completes the
removal of the Monitor object from migration code, started by the previous
commit.
Another important and tricky change is about supporting the non-detached
mode. That is, if the user doesn't pass '-d' the migrate command will lock
the monitor and will only release it when migration is finished.
To support this in the new HMP command (hmp_migrate()), it is necessary
to create a timer which runs every second and checks if the migration is
still active. If it is, the timer callback will re-schedule itself to run
one second in the future. If the migration has already finished, the
monitor lock is released and the user can use it normally.
All these changes should be transparent to the user.
