f787c409c4 vmm: cpu: Factorize vcpu starting code 
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.

13756490b5 vmm: cpu: Track all Vcpus through CpuManager 
In anticipation for the CpuManager to aggregate all Vcpu snapshots
together, this change makes sure the CpuManager has a handle onto
every vCPU.

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.
