Add support for "like" auto-detection and use as default comparison
operator.
Allows mimicking KeywordKey and DefaultKey with 2 parameters, in addition
to already-supported simple SearchKey.

MissingCategoryDocumentConstraint was incorrectly using
unrestrictedTraverse, unlike category API which uses its own
resolveCategory method with better semantics.

Because of this, some problems were not reported:
 - categories using paths that resolve by acquisition, but does not
exists as such (like in the test)
 - categories using path with dynamic objects, like a website language.

Thus we need to properly handle this use case otherwise simply failing makes "client
side" - i.e. testnode keep trying forever in its _retryRPC calls which
indefinitely blocks further tests executions.

A new test suite to perform static check on business templates using  `CodingStyleTestCase`.

This runs a coding style test for each business template, after installing the business template and its dependencies listed in business template metadata.

---

In order to start with a test suite with no failure, business templates that does not pass this test today (because they don't install or because pylint issues still needs to be reviewed) are skipped with an ad-hoc  `bt/skip_coding_style_test` in the business template. Note that this file is not created by business template system as it is a temporary measure, business templates must pass pylint and other checks from `CodingStyleTestCase`.

---

I took the approach of creating one independent test per business template, instead of the approach of creating a site with all business templates like we did in testNamingConventions or testHTML. This appears as another "Coding Style" test, like Performance or Scalability tests.

The idea behind this was that if we extend our business template checks ( for example when we translate the [ERP5 Module Creation Guidelines](https://www.erp5.com/documentation/developer/guideline/module) to some scripts we can run on a business template ), we can check that each business template contain what it should contain and not just that the global result is OK.

PortalTransforms: safe_html: Changes in b255c894 were not actually applied so merge FS module and portal_transforms/safe_html.

These titles duplicate listbox configuration, preventing any change from
reaching users (...who customised their listbox).
Also fixes cases where column title was stored in selection after
translation, which breaks some reports.

Avoid double-calls when one is enough.
Avoid unused locals.
Avoid repeating conditions.
Inline single-use expressions.

Bootstrap is actually the automatic migration of tools. It happened to me
several times that I mistakenly start an old instance on a too new version of
products and this instance is migrated automatically.

By leaving a note in transaction it's easier to find out which
transaction performed the automatic migration to revert to the state
before using technique such as
https://blog.gocept.com/2019/06/14/undo-transactions-by-truncating-zodb-data-fs/
for FileStorage.

with this change, a command such as;

    python -m ZODB.scripts.fstail -n 20 ./instance/slappart6/srv/zodb/root.fs

show something like:

    2019-11-12 02:46:42.106313: hash=44fecb9a63411fbf305cea82f4c699c478000d61
    user=' None' description='/timer_service/process_timer\nSite migrated' length=462938 offset=881877846 (+70)

for the transaction which did the migration, so it's easy to repair.

Also, ZODB Components Transforms modules were 'Document Component', whereas
it should be 'Module Component' (introduced recently) considering that they
have no Portal Type.

We'll gradually enable the business templates as we fix them.
