Both clang-tidy and cppcheck linting are handled by the same test file,
test/build/static_checkers. The two linters are independent of each other
though, and each one takes quite a long time. Split them into separate
files to make it easier to control which are executed from the top level
test script.

The test scripts support a "req" directive which requires one test script
to be run before another. It's implemented by doing a topological sort
based on these directives in the runner scripts, which is about as awkward
as you'd expect in Bourne shell.
It turns out we only use this functionality in one place - to make the
"make install" test run after the plain "make" test. We also already have
a simpler way of making sure tests run in a specific order: just put them
into the same test script file.
So, remove support for the "req" directive and just fold the build/all and
build/install test scripts together.

A number of individual test cases use '*out' commands to check for success
of specific commands they've issued. Now that the test harness is testing
for success of all issued commands as a matter of course, we no longer need
to do this.

Build-time selection of AVX2 flags and routines is not practical for
distributions, but limiting AVX2 usage to checksum routines with
specific run-time detection doesn't allow for easy performance gains
from auto-vectorisation of batched packet handling routines.
For x86_64, build non-AVX2 and AVX2 binaries, and implement a simple
wrapper replacing the current executable with the AVX2 build if it's
available, and if AVX2 is supported by the current CPU.

...mostly false positives, but a number of very relevant ones too,
in tcp_get_sndbuf(), tcp_conn_from_tap(), and siphash PREAMBLE().
