For example, if the test app fails to start on wayland, we'd block
~forever (ten minutes) waiting for it to render its first frame.
We don't have a good solution right now. But at least we can use a
relatively short timeout, to help out the human who rightfully expects
a result within ten seconds.
While at it, remove a sway "get_seats" command, which was a leftover
from my debugging of what input devices are available when running
headless.

We already wait for the app to render itself via the "frame ready"
stdout prints. Waiting for the canvas to be ready isn't really necessary
anymore. It helped us while we had to rely on sleeps, but that's no
longer the case.

The js/wasm bug meant that printing to stdout in the e2e app would crash
the runtime, so we couldn't synchronize with the app like in the other
drivers.
Now that the bug is fixed, we can do the same as the other drivers just
fine.

Now that we use tip due to breaking changes in Go's JS APIs, let's
replace our hacky cleanup list code with 1.14's upcoming
testing.T.Cleanup.
Adding more deliberate uses of tip would ususally be best avoided, but
these will only affect developers working on gio's tests, not regular
users of gio.
While at it, remove some debug t.Logf calls I forgot to remove.

This means we can deduplicate some of the logic, and keep it all in one
place.
Start expanding the logic too; the tests are slow, so they should be
skipped on 'go test -short'. The ones we have so far all run in a matter
of seconds on an average laptop today, but future tests will probably
require heavier work like wine or kvm.

In an earlier commit, we made it possible to run the e2e tests with the
race detector enabled everywhere via GOFLAGS=-race go test.
However, that's not at all standard; most users will simply use 'go test
-race'. Moreover, having 'go test -race' run the test program with the
race detector, but not the e2e gio app, is a bit useless.
Instead, have the tests detect when they run with the race detector, and
enable the race detector in the test app too. As before, the JS test is
skipped whenever -race is used.
This also means we can test with -race in the same way in each of the
modules, which simplifies CI.

Spotted the javac one by chance when reading the code, so I ran the tool
and fixed another small bug while at it.
Signed-off-by: Daniel Martí <mvdan@mvdan.cc>
Right now, we can only run the e2e gio app with -race, not without
-race, because the flag is hard-coded in the tests.
The reason for this change was that 'GOFLAGS=-race go test' would fail
with the JS test, since js/wasm doesn't support the race detector. Fix
that by skipping the JS test when -race is used.
Now, we can run multiple levels of -race:
go test # no -race at all
go test -race # -race for the tests, not the e2e gio app
GOFLAGS=-race go test # -race for everything (best-effort)
To detect the race detector being on, we use a file with a build tag.

It's not possible to set GOFLAGS=-race because some programs are
built for webassembly where -race is not supported.

Clicking doesn't quite work yet, but everything else does. We use a
custom sway config to ensure that it's a minimalist setup with no bar or
borders, like the other drivers.
The generic test now adapts to the window's real size when running in
non-headless mode, since tiling window managers resize some drivers like
sway. The default headless mode still expects the exact size that we
specify, as no real windows are at play.
While at it, clean up some now unused code from the x11 file.

We can instead synchronize with the gio app via stdout. We need three
states, since we need to first invalidate a frame and then print when
the next frame is drawn.
This is not happening on the JS test yet, because stdout printing
crashes in that case. See the comment.
This change should make the X11 test a bit faster on fast machines,
while making it more stable in small or headless machines like CI.

Instead rely on more tiny standalone tools. In this case, scrot lets us
take png screenshots, and works well.
On the plus side, we remove some large X Go deps, and we don't need
nearly as much code.
While at it, skip if any of the tools are missing, and actually defer
the cleanup funcs so that they run when we fail the test early.

The test app now responds to mouse clicks; clicking on one of the four
sections of the app flips it to red color until clicked again.
Add a Click method to the TestDriver interface, and implement it in both
of the current drivers. Unfortunately, I failed at implementing it in
X11 with the xdg library, after a few wasted hours. Instead, start
relying on more external tools which are simple to use and not heavy to
install.

The e2e app now splits the window into four rectangles and paints them
differently.
The first advantage is that we now test that we see the entire Gio app.
Before, with a solid background color, we could be seeing a small part
of the window and we wouldn't tell the difference.
The second advantage is that we test more colors. In particular, the
fourth color includes a different alpha value, which renders the same on
JS and X11.

Now we implement the "red background" end-to-end test exactly once.
While at it, start using a 800x600 window size, which is a bit more
realistic than 600x600, and will catch if we got either dimension wrong.
The interface only has two methods for now, but it will be expanded in
the future to also support input such as clicks.
Keeping state in the test driver, such as a context or a connection, is
a bit awkward but necessary so that we don't have to repeat arguments
over and over. The same applies to testing.T.

chromedp was defaulting to log.Printf, which is not good for tests.
The xgb and xgbutil logs were suppressed if -v wasn't given, but they
were sent straight to os.Stderr otherwise:
=== RUN TestX11
=== PAUSE TestX11
=== CONT TestX11
XGB: conn.go:47: Could not get authority info: EOF
XGB: conn.go:48: Trying connection without authority info...
--- PASS: TestX11 (0.87s)
Instead, direct their loggers to an io.Writer implementation that sends
its output to t.Logf:
=== RUN TestX11
=== PAUSE TestX11
=== CONT TestX11
TestX11: x11_test.go:187: XGB: conn.go:47: Could not get authority info: EOF
TestX11: x11_test.go:187: XGB: conn.go:48: Trying connection without authority info...
--- PASS: TestX11 (0.86s)
We do end up with duplicate log prefixes, but at least we don't write
straight to stderr, which will be a problem as we add more concurrent
tests.
