Implement ValidityState::badInput
 https://bugs.webkit.org/show_bug.cgi?id=102861

 Reviewed by NOBODY (OOPS!).

 Add ValidityState::badInput, add hasBadInput, which always returns
 false, to FormAssociatedElement, HTMLInputElement, and InputType.

  For NumberInputType, we had hasUnacceptableValue, which was a hack to
  make an input element match to :invalid if the element had non-number
  strings. We don't need the hack any more because badInput affects :invalid
  style. hasUnacceptableValue is re-used for hasBadInput implementation.
  We cleared invalid numbers when elements lost focus to tell users that
  the element had invalid numbers. We don't need this behavior because the
  interactive validation tells it.

  For date/time input types, we should make an input badInput when the
  input has empty value but its sub-fields have values. It covers both of
  partial input cases such as 12/--/2012 and invalid dates such as
  02/31/2012.

  For other types, ValidityState::badInput always returns false.

  This patch doesn't contain tests for badInput validation messages. They
  will be added later.

  * html/ValidityState.h:
  (ValidityState): Add badInput.
  * html/ValidityState.cpp:
  (WebCore::ValidityState::badInput):
  Added. Calls FormAssociatedElement::hasBadInput.

  * html/FormAssociatedElement.h:
  (FormAssociatedElement): Add hasBadInput.
  * html/FormAssociatedElement.cpp:
  (WebCore::FormAssociatedElement::hasBadInput):
  Added. It always returns false.
  (WebCore::FormAssociatedElement::valid): Takes account of hasBadInput().

  * html/HTMLInputElement.h:
  (HTMLInputElement):
  Remove hasUnacceptableValue, and add hasBadInput override.
  * html/HTMLInputElement.cpp:
  (WebCore::HTMLInputElement::hasBadInput):
  Added. Delegate to InputType::hasBadInput.
  (WebCore): Remove hasUnacceptableValue.

  * html/InputType.h:
  (InputType): Add hasBadInput and badInputText, and remove
  hasUnacceptableValue.
  * html/InputType.cpp:
  (WebCore::InputType::hasBadInput): Added. Returns false.
  (WebCore::InputType::badInputText):
  Added. This function should not be called because hasBadInput always
  returns false.
  (WebCore::InputType::validationMessage):
  Supports badInput. This returns badInputText if hasBadInput is true.

  * html/NumberInputType.h:
  (NumberInputType): Add hasBadInput and badInputTest. Remove
  handleBlurEvent and hasUnacceptableValue.
  * html/NumberInputType.cpp:
  Remove handleBlurEvent, which cleared invalid number strings.
  (WebCore::NumberInputType::hasBadInput):
  Added. We don't need to check existence of a renderer. The standard form
  validation feature doesn't care of it.
  (WebCore::NumberInputType::badInputText): Returns
  validationMessageBadInputForNumberText defined in LocalizedStrings.h.
  * css/SelectorChecker.cpp:
  (WebCore::SelectorChecker::checkOneSelector):
  Remove a hack for hasUnacceptableValue. isValidFormControlElement takes
  account of badInput.
  * dom/Element.h: Remove hasUnacceptableValue.

  * html/BaseMultipleFieldsDateAndTimeInputType.h:
  (BaseMultipleFieldsDateAndTimeInputType): Add hasBadInput and badInputText.
  * html/BaseMultipleFieldsDateAndTimeInputType.cpp:
  (WebCore::BaseMultipleFieldsDateAndTimeInputType::badInputText):
  Returns validationMessageBadInputForDateTimeText defined in LocalizedStrings.h.
  (WebCore::BaseMultipleFieldsDateAndTimeInputType::hasBadInput):
  Added.
  (WebCore::BaseMultipleFieldsDateAndTimeInputType::setValue):
  Add setNeedsValidityCheck call. It is needed because
  updateInnerTextValue can modify subfields empty state.

  * html/TextFieldInputType.cpp:
  (WebCore::TextFieldInputType::subtreeHasChanged): Update a comment.
  * platform/LocalizedStrings.h:
   (WebCore): Add validationMessageBadInputForNumberText and
   validationMessageBadInputForDateTimeText.
   * platform/LocalizedStrings.cpp:
   (WebCore::validationMessageBadInputForNumberText):
   Added a placeholder implementation. This should be fixed later.
