Fixed #8861 
* use ajax on PR review page

* handle review comments

* extract duplicate code

FetchCodeCommentsByLine was initially more or less copied from fetchCodeCommentsByReview. Now they both use a common findCodeComments function instead

* use the Engine that was passed into the method

* When replying to an outdated comment it should not appear on the files page

This happened because the comment took the latest commitID as its base instead of the
reviewID that it was replying to.

There was also no way of creating an already outdated comment - and a
reply to a review on an outdated line should be outdated.

* add request review feature in pull request

add a way to notify specific reviewers to review like github , by add  or delet a  special type
review . The acton is  is similar to Assign ,  so many code reuse the function and items of
Assignee, but the meaning and result is different.

The Permission style is is similar to github, that only writer can add a review request from Reviewers,
but the poster can recall and remove a review request after a reviwer has revied even if he don't have
Write Premission. only manager , the poster and reviewer of a request review can remove it.

The reviewers can be requested to review contain all readers for private repo , for public, contain
all writers and watchers.

The offical Review Request will block merge if Reject can block it.

an other change: add ui otify for Assignees.
