test_progs's IMA selftests requires extra Kconfig values, so update
latest.config to accommodate those.

tcpbpf_user uses cgroup bpf_link, not available in 5.5. hash_large_key is
testing a more permissive verifier check, implemented in 5.11. So blacklist
both.

Blacklist new tests that are depending on features in latest kernel. Also
temporarily blacklist raw_tp_test_run test, until it is fixed upstream.

Blacklist btf_map_in_map permanently for 5.5. bpf_verif_scale is broken due to
Clang issues on latest. Do not run ALU32 flavor for test_progs on 4.9.0, which
doesn't support ALU32 yet.

Drop blacklist and instead use a small whitelist of tests that are still
supposed to work on old 4.9 kernel.

Make sure that libbpf sanitizes BTF properly for older kernels.
Add a stage for 4.9.0 kernel in TravisCI.
For now make test failures non-blocking by adding 4.9.0 to `allow_failures`
section.
Blacklist is copy-pasted 5.5.0 kernel blacklist.
Now that pre-generated vmlinux.h is used for compilation of non-latest tests,
we don't need custom adjustments for 5.5 kernel selftests. Adjust blacklist
now that those new self-tests are built into test_progs.

Manually generate vmlinux.h based on latest.config to be used for non-latest
selftest build. This will keep bpftool and newest selftests builds succeeding,
while at runtime blacklist will skip them.

Permanently blacklist load_bytes_relative test on 5.5 due to missing
functionality.
Also temporarily blacklist core_reloc test due to failure on latest kernel.

Disable a bunch of new kernel selftests that can't succeed on 5.5 kernel.
Flatten Travis tests into a single stage to parallelize and speed them up.

bpf_obj_id selftest added testing of bpf_link related operations, which are
not implemented in 5.5.0. Blacklist it.

5.5 kernel has a bug in kernel allowing to violate read-only access to
mmap()-ed map. Disable selftest that now is failing.

Enable now-fixed sockmap_listen tests. Disabled vmlinux test on 5.5, on which
hrtimer_nanosleep() signature is incompatible. Filled out remaining
permanently disabled tests resons.

With fixes in selftests, these tests should now pass.
Also add ability to add comments to blacklist/whitelist to explain why certain
test is disabled.

The disk image is updated to 2020-03-11.
blacklist for LATEST kernel:
attach_probe (needs root cause)
perf_buffer (needs root cause)
send_signal (flaky)
sockmap_listen (flaky)
Run test_maps and test_verifier.
test_maps is not expected to pass for kernels other then LATEST.

vmtest is run as a TravisCI job in order to test libbpf backward compatibility
with the older kernels
Add config files required to build and run bpf kernel selftests in vmtest:
- latest.config: latest kernel config
- INDEX: links to binaries (kernels, disk image) to download
- blacklist/BLACKLIST-${kernel}: blacklisted bpf program tests for ${kernel}
