Before this path, [Param_tags.init()] was run before
[Plugin.execute_plugin_if_needed()]. It had the downside of making
plugin compilation warn about any unknown parametrized tag present in
a _tags file, even those that would be defined by the plugin
itself. The fix is to [really_acknowledge] only the tags used for the
plugin compilation, and delay the full [Param_tags.init()] call to
after plugin execution.
This was discussed in detail in PR#5680, comment 0010186.

If in the future we want to be able to use information from _tags when
compiling the myocamlbuild.ml plugin, we should compile the plugin
*after* the OCaml-tags rules of Ocaml_specific have been loaded
(OCaml_specific.init()). This patch does not change the plugin
compilation, but it delays it to the end of the initialization phase
to allow such future changes.
This means that the parsing of configuration files
(including traversing directories to find _tags files in depth) will
be done twice (once during the first run to compile the plugin, and
then once when run from the plugin). Of these operations, the only
that has user-visible consequences (and the first candidate to
performance degradations) is the hygiene checking, which we therefore
disable during the first run. Note that checksumming files is not
duplicated (it is done after the initialization phase).
Note that the semantics of _tags files in subdirectories is that they
are only ranging over files in that subhierarchy (even "true: foo"
lines do not apply to the files in ancestor or
sibling directories). This means that no _tags file in a subdirectory
can add tags to "myocamlbuild.ml". If performance of file traversing
ever was to become an issue, we could therefore skip it and read only
the root _tags file if present.

You can still have a fine grained control using your _tags
file and the "traverse" tag.
There is no longer the "true: traverse" tag declaration by default.
To make ocamlbuild recursive use one of these:
1) Give the -r flag to ocamlbuild.
2) Have a _tags or myocamlbuild.ml file in your top directory.

.depends file was generated by an ugly rule that executed the ocamldep
command instead of returning it for later execution. Moreover this execution
was in order to read the output and store as a side effect. By doing this it
was more complicated to work with this command. Now the rule just returns the
command to execute as for other rules. And that's clients that wants
dependencies of a file that trigger the reading of this file.

There is now an abstract type to ensure that resource_patterns are not mixed
with resources. Rules are now 'a gen_rules where 'a is the type of production
resources (either a resource or a resource_pattern).
