In order to snapshot the content of the guest RAM, the MemoryManager
must implement the Snapshottable trait.

Implement the Snapshottable trait for Vcpu, and then implements it for
CpuManager. Note that CpuManager goes through the Snapshottable
implementation of Vcpu for every vCPU in order to implement the
Snapshottable trait for itself.

Anticipating the need for a slightly different function for restoring
vCPUs, this patch factorizes most of the vCPU creation, so that it can
be reused for migration purposes.

These two new helpers will be useful to capture a vCPU state and being
able to restore it at a later time.

In anticipation for the CpuManager to aggregate all Vcpu snapshots
together, this change makes sure the CpuManager has a handle onto
every vCPU.

Based on the list of Migratable devices stored by the DeviceManager, the
DeviceManager can implement the Snapshottable trait by aggregating all
devices snapshots together.

Serial and Ioapic both implement the Migratable trait, hence the
DeviceManager can store them in the list of Migratable devices.

The parse_size helper function can now be consolidated into the
ByteSized FromStr implementation.

Now all parsing code makes use of the Toggle and it's FromStr support
move the helper function into the from_str() implementation.

The integration tests and documentation make use of empty value strings
like "--net tap=" accept them but return None so that the default value
will be used as expected.

This simplifies the parsing of the option by using OptionParser along
with its automatic conversion behaviour.
Signed-off-by: Rob Bradford <robert.bradford@intel.com>
Byte sizes are quantities ending in "K", "M", "G" and by implementing
this type with a FromStr implementation the values can be converted
using .parse().

Before porting over to OptionParser add a unit test to validate the
current memory parsing code. This showed up a bug where the "size=" was
always required. Temporarily resolve this by assigning the string a
default value which will later be replaced when the code is refactored.

This will be used to simplify and consolidate much of the parsing code
used for command line parameters.
