The classes that set tests for the block-stream command with discard

Some QMP commands do not have the optional 'discard' argument because

Currently disas.c reads physical memory using
cpu_physical_memory_read(). This effectively hard-codes
assuming that all CPUs have the same view of physical
memory. Switch to address_space_read() instead, which
lets us use the AddressSpace for the CPU we're
disassembling for.

We introduce a new msi_bypass field which indicates whether
the IOAPIC MSI window [0xFEE0 - 0xFEEF] must be exposed
as a reserved region. By default the field is set to true at
instantiation time. Later on we will introduce a property at
virtio pci proxy level to turn it off.

This patchset takes three places in generic code which
use cpu_physical_memory_read(), and changes them to use
address_space_read() instead.
Changes v1->v2:
* patches 1, 2 unchanged (and reviewed)
* patch 3: handle as being NULL (which for the
load_elf APIs means "use address_space_memory")
When translating an address we need to check if it belongs to
a reserved virtual address range. If it does, there are 2 cases:
- it belongs to a RESERVED region: the guest should neither use
this address in a MAP not instruct the end-point to DMA on
them. We report an error
- It belongs to an
