Perf dashboard should provide a way to associate bugs with a test run
https://bugs.webkit.org/show_bug.cgi?id=137857

Reviewed by Andreas Kling.

Added a "privileged" API, /privileged-api/associate-bug, to associate a bug with a test run.
/privileged-api/ is to be protected by an authentication mechanism such as DigestAuth over https by
the Apache configuration.

The Cross Site Request (CSRF) Forgery prevention for privileged APIs work as follows. When a user is
about to make a privileged API access, the front end code obtains a CSRF token generated by POST'ing
to privileged-api/generate-csrf-token; the page sets a randomly generated salt and an expiration time
via the cookie and returns a token computed from those two values as well as the remote username.

The font end code then POST's the request along with the returned token. The server side code verifies
that the specified token can be generated from the salt and the expiration time set in the cookie, and
the token hasn't expired.

* init-database.sql: Added bug_url to bug_trackers table, and added bugs table. Each bug tracker will
have zero or exactly one bug associated with a test run.

* public/admin/bug-trackers.php: Added the support for editing bug_url.
* public/api/runs.php:
(fetch_runs_for_config): Modified the query to fetch bugs associated with test_runs.
(parse_bugs_array): Added. Parses the aggregated bugs and creates a dictionary that maps a tracker id to
an associated bug if there is one.
(format_run): Calls parse_bugs_array.

* public/include/json-header.php: Added helper functions to deal for CSRF prevention.
(ensure_privileged_api_data): Added. Dies immediately if the request's method is not POST or doesn't
have a valid JSON payload.
(ensure_privileged_api_data_and_token): Ditto. Also checks that the CSRF prevention token is valid.
(compute_token): Computes a CSRF token using the REMOTE_USER (e.g. set via BasicAuth), the salt, and
the expiration time stored in the cookie.
(verify_token): Returns true iff the specified token matches what compute_token returns from the cookie.

* public/include/manifest.php:
(ManifestGenerator::bug_trackers): Include bug_url as bugUrl in the manifest. Also use tracker_id instead
of tracker_name as the key in the manifest. This requires changes to both v1 and v2 front end.

* public/index.html:
(Chart..showTooltipWithResults): Updated for the manifest format changed mentioned above.

* public/privileged-api/associate-bug.php: Added.
(main): Added. Associates or dissociates a bug with a test run inside a transaction. It prevent a CSRF
attack via ensure_privileged_api_data_and_token, which calls verify_token.

* public/privileged-api/generate-csrf-token.php: Added. Generates a CSRF token valid for one hour.

* public/v2/app.css:
(.disabled .icon-button:hover g): Used by the "bugs" icon when a range of points or no points are
selected in a chart.

* public/v2/app.js:
(App.PaneController.actions.toggleBugsPane): Added. Toggles the visibility of the bugs pane when exactly
one point is selected in the chart. Also hides the search pane when making the bugs pane visible since
they would overlap on each other if both of them are shown.
(App.PaneController.actions.associateBug): Makes a privileged API request to associate the specified bug
with the currently selected point (test run). Updates the bug information in "details" and colors of dots
in the charts to reflect new states. Because chart data objects aren't real Ember objects for performance
reasons, we have to use a dirty hack of modifying a dummy counter bugsChangeCount.
(App.PaneController.actions.toggleSearchPane): Renamed from toggleSearch. Also hides the bugs pane when
showing the search pane.
(App.PaneController.actions.rangeChanged): Takes all selected points as the second argument instead of
taking start and end points as the second and the third arguments so that _showDetails can enumerate all
bugs in the selected range.

(App.PaneController._detailsChanged): Added. Hide the bugs pane whenever a new point is selected.
Also update singlySelectedPoint, which is used by toggleBugsPane and associateBug.
(App.PaneController._currentItemChanged): Updated for the _showDetails change.
(App.PaneController._showDetails): Takes an array of selected points in place of old arguments.
Simplified the code to compute the revision information. Calls _updateBugs to format the associated bugs.
(App.PaneController._updateBugs): Sets details.bugTrackers to a dictionary that maps a bug tracker id to
a bug tracker proxy with an array of (bugNumber, bugUrl) pairs and also editedBugNumber, which is used by
the bugs pane to associate or dissociate a bug number, if exactly one point is selected.

(App.InteractiveChartComponent._updateDotsWithBugs): Added. Sets hasBugs class on dots as needed.
(App.InteractiveChartComponent._setCurrentSelection): Finds and passes all points in the selected range
to selectionChanged action instead of just finding the first and the last points.

* public/v2/chart-pane.css: Updated the style.

* public/v2/data.js:
(PrivilegedAPI): Added. A wrapper for privileged APIs' CSRF tokens.
(PrivilegedAPI.sendRequest): Makes a privileged API call. Fetches a new CSRF token if needed.
(PrivilegedAPI._generateTokenInServerIfNeeded): Makes a request to privileged-api/generate-csrf-token if
we haven't already obtained a CSRF token or if the token has already been expired.
(PrivilegedAPI._post): Makes a single POST request to /privileged-api/* with a JSON payload.

(Measurement.prototype.bugs): Added.
(Measurement.prototype.hasBugs): Returns true iff bugs has more than one bug number.
(Measurement.prototype.associateBug): Associates a bug with a test run via privileged-api/associate-bug.

* public/v2/index.html: Added the bugs pane. Also added a list of bugs associated with the current run in
the details.

* public/v2/manifest.js:
(App.BugTracker.bugUrl):
(App.BugTracker.newBugUrl): Added.
(App.BugTracker.repositories): Added. This was a missing back reference to repositories.
(App.MetricSerializer.normalizePayload): Now parses/loads the list of bug trackers from the manifest.
(App.Manifest.repositoriesWithReportedCommits): Now initialized to an empty array instead of null.
(App.Manifest.bugTrackers): Added.
(App.Manifest._fetchedManifest): Sets App.Manifest.bugTrackers. Also sorts the list of repositories by
their respective ids to make the ordering stable.
