Moved the commands to resize the shell to their own method. They are
now executed twice. Once as soon as the shell is connected, and a
second time as part of initialize. This latter call takes place after
the isntallation of busybox.
- This patch addresses an issue with the arguments passed the
BaseGem5Device __init__. With this patch these are no longer passed
in as they are not required in the base device implementation.
- Refactored the Gem5Device to avoid duplicated code. There is now a
BaseGem5Device which includes all of the shared functionality. The
Gem5LinuxDevice and the Gem5AndroidDevice both inherit from
BaseGem5Device, and LinuxDevice or AndroidDevice, respectively.
