Subject: Update JSON-PP to CPAN version 4.00

[DELTA]

4.00 2018-12-07
- production release

3.99_01 2018-12-03
- BACKWARD INCOMPATIBILITY:
As JSON::XS 4.0 changed its policy and enabled allow_nonref
by default, JSON::PP also enabled allow_nonref by default

- implement allow_tags that was introduced by JSON::XS 3.0
- add boolean_values that was introduced by JSON::XS 4.0
- allow literal tags in strings in relaxed mode, as JSON::XS 3.02 does
- allow PERL_JSON_PP_USE_B environmental variable to restore
old number detection behavior for compatibility
- various doc updates

 =over 4
 
-=item 1. C<convert_blessed> is enabled and the object has a C<TO_JSON> method.
+=item 1. C<allow_tags> is enabled and the object has a C<FREEZE> method.
+
+In this case, C<JSON::PP> creates a tagged JSON value, using a nonstandard
+extension to the JSON syntax.
+
+This works by invoking the C<FREEZE> method on the object, with the first
+argument being the object to serialise, and the second argument being the
+constant string C<JSON> to distinguish it from other serialisers.
+
+The C<FREEZE> method can return any number of values (i.e. zero or
+more). These values and the paclkage/classname of the object will then be
+encoded as a tagged JSON value in the following format:
+
+   ("classname")[FREEZE return values...]

+
+   ("URI")["http://www.google.com/"]
+   ("MyDate")[2013,10,29]
+   ("ImageData::JPEG")["Z3...VlCg=="]

+=head3 DESERIALISATION
+
+For deserialisation there are only two cases to consider: either
+nonstandard tagging was used, in which case C<allow_tags> decides,
+or objects cannot be automatically be deserialised, in which
+case you can use postprocessing or the C<filter_json_object> or
+C<filter_json_single_key_object> callbacks to get some real objects our of
+your JSON.
+
+This section only considers the tagged value case: a tagged JSON object
+is encountered during decoding and C<allow_tags> is disabled, a parse
+error will result (as if tagged values were not part of the grammar).
+
+If C<allow_tags> is enabled, C<JSON::PP> will look up the C<THAW> method
+of the package/classname used during serialisation (it will not attempt
+to load the package as a Perl module). If there is no such method, the
+decoding will fail with an error.
+
+Otherwise, the C<THAW> method is invoked with the classname as first
+argument, the constant string C<JSON> as second argument, and all the
+values from the JSON array (the values originally returned by the
+C<FREEZE> method) as remaining arguments.
+
+The method must then return the object. While technically you can return
+any Perl scalar, you might have to enable the C<allow_nonref> setting to
+make that work in all cases, so better return an actual blessed reference.
+
+As an example, let's implement a C<THAW> function that regenerates the
+C<My::Object> from the C<FREEZE> example earlier:
+
+   sub My::Object::THAW {
