fixup! support sort on both the full text search score and the column value itself.

* ignore sort on full text search score if no full text search happens.
* escape table name and column name in order_by_dict.
fulltext: escape some characters in Mroonga boolean search queries.
ERP5Type.patches.Restricted: Allow access to hash instances.
syncml : even when do not create signature, try to get the document for an update
use TokenBigramSplitSymbolAlphaDigit parser instead of TokenBigramSplitSymbolAlpha by default.

so that we have less misses even though we have more noises.

to migrate, you can use the following SQL :

ALTER TABLE catalog_full_text
  DROP KEY title,
  DROP KEY description,
  ENGINE=mroonga,
  ADD FULLTEXT KEY title (`title`) COMMENT 'parser "TokenBigramSplitSymbolAlphaDigit"',
  ADD FULLTEXT KEY description (`description`) COMMENT 'parser "TokenBigramSplitSymbolAlphaDigit"';

ALTER TABLE content_translation
  DROP KEY translated_text,
  ENGINE=mroonga,
  ADD FULLTEXT KEY translated_text (`translated_text`) COMMENT 'parser "TokenBigramSplitSymbolAlphaDigit"';

ALTER TABLE full_text
  DROP KEY SearchableText,
  ENGINE=mroonga,
  ADD FULLTEXT KEY SearchableText (`SearchableText`) COMMENT 'parser "TokenBigramSplitSymbolAlphaDigit"';
erp5_hal_json_style: check if isWebMode is present before calling it.
ERP5Type.patches.OFSItem: Explicitly declare volatileCached public.
