migration: stable ram block ordering

This makes ram block ordering under migration stable, ordered by offset.
This is especially useful for migration to exec, for debugging.

Add Intel HD Audio support to qemu.

This patch adds three devices to qemu:

intel-hda
Intel HD Audio Controller, the PCI device. Provides a HDA bus.
Emulates ICH6 at the moment. Adding a ICH9 PCIE
variant shouldn't be hard.

hda-duplex
HDA Codec. Attaches to the HDA bus. Supports 16bit stereo,...

migration: don't segfault on invalid input

host_from_stream_offset returns NULL on error,
return error instead of trying to use that address,
to avoid segfault on invalid stream.

Introduce qemu_madvise()

vl.c has a Sun-specific hack to supply a prototype for madvise(),
but the call site has apparently moved to arch_init.c.

Haiku doesn't implement madvise() in favor of posix_madvise().
OpenBSD and Solaris 10 don't implement posix_madvise() but madvise()....

savevm: Reset last block info at beginning of each save

If we save more than once we need to reset the last block info or else
only the first save has the actual block info and each subsequent save
will only use continue flags, making them unloadable independently....

ramblocks: No more being lazy about duplicate names

Now that we have a working qemu_ram_free() and the primary runtime
user of it has been updated, don't be lenient about duplicate id strings.
We also shouldn't need to create them ondemand at the target....

savevm: Migrate RAM based on name/offset

Synchronize RAM blocks with the target and migrate using name/offset
pairs. This ensures both source and target have the same view of
RAM and that we get the right bits into the right slot.

savevm: Use RAM blocks for basis of migration

We don't want to assume a contiguous address space, so migrate based
on RAM blocks instead of a fixed linear address map. This will allow
us to have holes in the ram_addr_t namespace, so we can implement
qemu_ram_free()....

savevm: Create a new continue flag to avoid resending block name

Allows us to compress the protocol a bit by setting a flag on the
offset which indicates we're still working within the same block
as last time. That way we can avoid sending the block name for...

Remove uses of ram.last_offset (aka last_ram_offset)

We currently need this either to allocate the next ram_addr_t for a
new block, or for total memory to be migrated. Both of which we can
calculate without need of this to keep us in a contiguous address space....

migration: Fix calculation of bytes_transferred

When a page with all identical bytes is transferred, it is counted
as a full page (TARGET_PAGE_SIZE) although only one byte is actually
sent. Fix this by changing ram_save_block() to return the number of
bytes sent instead of a boolean value. This makes bandwidth...

Refactor target specific handling, compile vl.c only once

architectures the option is allowed, check the flag
