automatically detect dictionary terms in nodes

The D10/D9 version, as of 8.x-1.0-alpha1, ships with a Definition filter plugin replicating the legacy hook_filter handling older versions used to have.

The way it has been designed is to support another Automatic filter plugin that will automatically (hence the name) identify words matching G2 entries and wrap them in a <dfn> element so that the

Definition/code> filter can then handle them.

The keys to solving the underlying issues are the discovery of Aho-Corasick (already implemented and tested in alpha1) and the idea of having a "stop list" to avoid matching G2 entries that could be false positives. 

That way, when a term in the stop list still needs to be linked (as opposed to being a false positive), the author can still manually use a <code><dfn>

element to generate the definition link, but it will not be automatically added.

First step: the base filter and its configuration.

Multi-pattern matcher and filter implemented. Need more integration testing.

Stop list handled, with different values per input format. Seems to be feature-complete.

15 years later, merged to current dev HEAD. Thanks all.
