This patch adds a base for testing kernel boot recording and replaying.
Each test has the phase of recording and phase of replaying.
Virtual machines just boot the kernel and do not interact with
the network.
Structure and image links for the tests are borrowed from boot_linux_console.py
Testing controls the message pattern at the end of the kernel
boot for both record and replay modes. In replay mode QEMU is also
intended to finish the execution automatically.
