This patch adds minimal integration test infrastructure for x86_64 and adds 20 integration tests to cover the following commands under x86_64: - pt - pt -kaslr - pt -has - pt -after - pt -before - pt -range - pt -filter ... - pt -ss, pt -s4, p4 -s8 Patch is for issue #11

This patch adds the infrastructure to generate custom x86_64 kernels that enter long mode and a generate page table. Each generated kernel binary generates a single page table that is chosen at compile time. For example, this patch adds these 3 tests for page table generation: - x86_64_test_entry_setup_4k_page_table_simple.bin - x86_64_test_entry_setup_4k_page_table_complex.bin - x86_64_test_entry_setup_2mb_page_table_simple.bin Each binary is a floppy-disk image. The binaries can be used to have the QEMU VM's page tables in a deterministic state. The output can be used to generate audited golden images that can be in the future compared against when running integration tests. Patch is for issue #11

This patch adds integration tests for aarch64. This is done by abstracting the test infra to support more than a single vm arch and then parametrizing the existing integration tests. This patch also adds a small aarch64 bios for setting up page tables. This bios is used for the pre-existing aarch64 golden image testing. Currently, only 3 golden tests are added: test_granularity_4k, test_granularity_16k, test_granularity_64k Patch is for issue #11

This patch adds a simple x86_32 test that covers pt and pt -ss. The Kolibri OS was chosen since I had a local floppy image and the OS is fairly small. For issue #11

This patch does the following: - Adds a fixture to handle init and deinit - Parametrize Linux kernel image to handle Linux and arch pecularities like KPTI and aarch64 page granules. - Update aarch64's default base image addr to be a list of possible addresses. - Add two debug env variables: GDB_PT_DUMP_TESTS_PAUSE_AFTER_BOOT and GDB_PT_DUMP_TESTS_PAUSE_AFTER_BOOT For issue #11

The project has a bunch of features which are not well-tested and protected against regressions. Tests are necessary to continue development.
