Follow-up for commit 98e7a29a (component/trafficserver: Version up to
9.0.2).

Drop patch from pull-request 7577, as it has since been merged upstream.

Zodburi 2.5.0 added support for demo: URI scheme:
https://github.com/Pylons/zodburi/blob/master/CHANGES.rst#250-2021-05-12

- due to a thinko in c170fe3e (ZODB: Provide ZODB4-wc2 which backports MVCC approach from ZODB5)
  4-wc2 revision was set on a ZEO(egg) section instead of ZEO(repository)
  section. As the result it was ZEO4 - not ZEO4-wc2 - that was installed.

  This was leading to hangs in tests with wcfs waiting for ZODB server to
  update it after a commit, but no notification was coming from ZEO at all.

  For the refrence: the reason ZEO4-wc2 exists at all is the backport patches
  that teach ZEO to send invalidations even on empty transactions
  (nexedi/ZEO@bf80d23d), and to include
  just-created objects into invalidations as well (nexedi/ZEO@f2fae122).
  Those changes are needed for WCFS to be always notificated on every
  transaction and with full set of changed objects.

- there was a typo: it was `revisions` instead of `revision`.

-> Fix both issues. Now it is ZEO4-wc2 that is installed for real when `ZODB.major = 4-wc2`.

The promise is commented out because it fails inside a test suite
due to port conflicts with the testnode of the test suite.

`srv/testnode/abc/inst/test0-0`  -> `t/abc/i/0`

Replace `softwaretype` recipe with `switch-softwaretype`

This is similar to d67f382f (wendelin.core: Fix test build 2)

Always reference to in-tree eggs via ${<name>:egg} instead of just name. This fixes e.g. the following build failure:

    Installing wendelin.core-python.
    While:
      Installing wendelin.core-python.
      Base installation request: 'wendelin.core[test]', 'pygolang[pyx.build]', 'neoppod[tests]', 'ZEO[test]'
      Getting distribution for 'ZEO[test]'.
    Error: Picked: ZEO = 5.2.3

Not sure why it worked before.

Neoppod is a bit special - leave it as is for now.

This teaches nxdtest to detect leaked processes and to clean them up
automatically instead of letting tests stuck because of them. See
nexedi/nxdtest@0ad45a9c and
nexedi/nxdtest!9 for details.

New dependencies of nxdtest are:

- psutil (already covered by stack/slapos.cfg),
- pytest-timeout, and
- setproctitle

These comments are not updated automatically and very hard to update manually,
so it's better not to have them.

This also adds a headless-chromium component and enables the http_sub
module in the Nginx component. Some basic tests are included. See merge
request nexedi/slapos!1014 for more details and discussion.

This change includes a rewrite of the previous
component/headless-chromium, which used an outdated version of Chromium.
It differs from component/chromium in that:

- It only provides a headless shell, rather than the full Chromium
  browser (though this can be changed).
- It compiles from source rather than downloading a binary build.

There is also a new software release software/headless-chromium which
makes use of the updated component/headless-chromium to expose a remote
debugging port.

Wendelin.core2[test] depends on scipy[1]. Before slapos.buildout
2.7.1+slapos013 the build was succeeding because scipy was, likely, installed
via binary wheel. But after that buildout upgrade the build fails:

ZEO 5.2.3 fixes several client concurrency bugs that could result in
data corruption. See changelog in https://pypi.org/project/ZEO/5.2.3/
for details.

trollius 2.2.post1 -> 2.2.1 update fixes "bad file descriptor" problem for ZEO5.
See https://github.com/zopefoundation/ZEO/issues/176 for details.

futures 3.2.0 -> 3.3.0 update brings in more efficient use of threads in
ThreadPoolExecutor. See https://github.com/agronholm/pythonfutures/blob/master/CHANGES.rst#330
for details.

It can take a little time before everything is ready and we don't have a
promise for this, because it's really application level.

See merge request nexedi/slapos!1031

This propery has a default, which indicates that it is not required.

https://rjsf-team.github.io/react-jsonschema-form/ can handle this
correctly, but needs a default along with the const.

Most tools work without this, but it's cleaner to define this anyway

This reverts commit f34aeeab.

this had the side effect of installing `promise-check-free-disk-space` which
is still used - at least by caddy tests.

In the test output, there are lots of tracebacks like this one:

    "./software/caddy-frontend/test/test.py", line 534, in do_GET
        for header in config.pop('X-Drop-Header', '').split():
    AttributeError: 'NoneType' object has no attribute 'split'

this does not seem to impact the test result, but it makes the result hard to
read.

Now that slapos-node-software service does not use --all we have to use another
approach for this test which re-installs an already installed software.

Use the slapos-node-software-all services which was made for similar use cases.

This was changed as part of b049c057 (upgrade to slapos.toolbox version
0.123, 2021-07-19), but this is not a slapos.toolbox promise plugin, it's
still an old style promise.

when running on test nodes some promise fail because testnode itself has
monitoring and the promise connects to testnode's own monitoring.

This reveals a real problem, but we need to fix testnode first to be able
to use this.

With gcc 6.3.0 we see build failures:

    error: no matching function for call to 'tesseract::STRING::STRING()'

According to https://github.com/tesseract-ocr/tesseract/issues/3210#issuecomment-774599019
minimal gcc version is version 7.

This probably started to break since d6dd75df (component/ghostscript:
version up 9.54.0, 2021-05-25) and 5f616dd7 (component/tesseract: version
up 4.1.1, 2021-05-20).

This gcc is needed for both tesseract and ghostscript, because ghostscript
build again its embedded copy of tesseract.

In b049c057 (upgrade to slapos.toolbox version 0.123, 2021-07-19), we
translated check-secure = 1 to config-http-code = 401, but check-secure = 1
also accepted responses with status code 200.

Thoses promises where checking servers without authentication enabled, they
reply with 200, so update the promises accordingly to expect 200.
