field.default.inc
Default 'implementations' of hook_field_*(): common field housekeeping.
Those implementations are special, as field.module does not define any field types. Those functions take care of default stuff common to all field types. They are called through the _field_invoke_default() iterator, generally in the corresponding field_attach_[operation]() function.
