Make render_as_link() in views_handler_field alterable [#2580139]

Problem/Motivation

Guess you created a custom field hander and would like provide some additional options for "Output this field as a link" (i.e. adding an attribute). Currently you will have to copy the function render_as_link() and make your modifications.

Proposed resolution

Add a possibility to alter the link parameters directly before passing it to the l()-function.

Remaining tasks

User interface changes

None.

API changes

New function alter_render_as_link(&$text, &$path, &$options, array $context) { } in views_handler_field.

Data model changes

None.

Patch introduces the new function.

Example usage in custom field handler class:

<?php
function alter_render_as_link(&$text, &$path, &$options, array $context) {
  $id = strtr($context['alter']['link_id'], $context['tokens']);
  if ($id) {
    $options['attributes']['id'] = array($id);
  }
}
?>

Is it useful to have this in Drupal 8? If yes, will the backport policy apply?

Yes, this may apply to Drupal 8, too.
But: after looking at FieldPluginBase::renderAsLink() I guess one can simply override the renderer used for the custom field handler and inject the modifications into the render-array.

The 3 year old patch in #2 to views_handler_field.inc does not apply to the latest views 7.x-3.x-dev and if still relevant needs to be rerolled.
