qapi: add dirty bitmap status
Bitmaps can be in a handful of different states with potentially
more to come as we tool around with migration and persistence patches.
Management applications may need to know why certain bitmaps are
unavailable for various commands, e.g. busy in another operation,
busy being migrated, etc.
Right now, all we offer is BlockDirtyInfo's boolean member 'frozen'.
Instead of adding more booleans, replace it by an enumeration member
'status' with values 'active' and 'frozen'. Then add new value
'disabled'.
Incompatible change. Fine because the changed part hasn't been
released so far.

target-arm: Avoid buffer overrun on UNPREDICTABLE ldrd/strd
A LDRD or STRD where rd is not an even number is UNPREDICTABLE.
We were letting this fall through, which is OK unless rd is 15,
in which case we would attempt to do a load_reg or store_reg
to a nonexistent r16 for the second half of the double-word.
Catch the odd-numbered-rd cases and UNDEF them instead.
To do this we rearrange the structure of the code a little
so we can put the UNDEF catches at the top before we've
allocated TCG temporaries.

hw/arm/virt-acpi-build: Basic framework for building ACPI tables on ARM
Introduce a preliminary framework in virt-acpi-build.c with the main
ACPI build functions. It exposes the generated ACPI contents to
guest over fw_cfg.
The required ACPI v5.1 tables for ARM are:
- RSDP: Initial table that points to XSDT
- RSDT: Points to FADT GTDT MADT tables
- FADT: Generic information about the machine
- GTDT: Generic timer description table
- MADT: Multiple APIC description table
- DSDT: Holds all information about system devices/peripherals, pointed by FADT

When migrating a guest, be sure to include the vector registers.
The vector registers are defined in a subsection, similar to the

we can skip them when performing the migration of the vector
registers which may or may not be present.

net/net: Record usage status of mac address
Currently QEMU dynamically generates mac address for the NIC which
doesn't specify the mac address. But when we hotplug a NIC without
specifying mac address, the mac address will increase for the same NIC
along with hotplug and hot-unplug, and at last it will overflow. And if
we codeplug one NIC with mac address e.g. "52:54:00:12:34:56", then
hotplug one NIC without specifying mac address and the mac address of
the hotplugged NIC is duplicate of "52:54:00:12:34:56".
This patch add a mac_table to record the usage status and free the mac
address when the NIC is unrealized.
