be32065aa4 vmm: config: Add "ByteSized" type for simplifying parsing of byte sizes 
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().

929142bc2e vmm: config: Add memory parsing unit test 
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.

1b1a2175ca vm-migration: Define the Snapshottable and Transportable traits 
A Snapshottable component can snapshot itself and
provide a MigrationSnapshot payload as a result.

A MigrationSnapshot payload is a map of component IDs to a list of
migration sections (MigrationSection). As component can be made of
several Migratable sub-components (e.g. the DeviceManager and its
device objects), a migration snapshot can be made of multiple snapshot
itself.
A snapshot is a list of migration sections, each section being a
component state snapshot. Having multiple sections allows for easier and
backward compatible migration payload extensions.

Once created, a migratable component snapshot may be transported and this
is what the Transportable trait defines, through 2 methods: send and recv.
