There is no need to include serde_derive separately,
as it can be specified as serde feature instead.

Always properly initialize vectors so that we don't run in undefined
behaviors when the vector gets dropped.

Instead of creating a MemoryManager from scratch, let's reuse the same
code path used by snapshot/restore, so that memory regions are created
identically to what they were on the source VM.

During snapshot/restore we will need to store this structure, which is
why it must derive the Versionize trait.

This will be helpful to support the creation of a MemoryRangeTable from
virtio-mem, as it uses 2M pages.

In anticipation for supporting the merge of multiple dirty pages coming
from multiple devices, this patch factorizes the creation of a
MemoryRangeTable from a bitmap, as well as providing a simple method for
merging the dirty pages regions under a single MemoryRangeTable.

error: methods called `as_*` usually take self by reference or self by mutable reference; consider choosing a less ambiguous name

Prior to sending the memory the full state is not needed only the
configuration. This is sufficient to create the appropriate structures
in the guest and have the memory allocations ready for filling.
Update the protocol documentation to add a separate config step and move
the state to after the memory is transferred. As the VM is created in a
separate step to restoring it the requires a slightly different
constructor as well as saving the VM object for the subsequent commands.
