Due to animations, DOM might get destroyed much later than scope and so the element $destroy event
might get fired outside of $digest, which causes changes to the validation model go unobserved
until the next digest. By deregistering on scope event, the deregistration always happens
in $digest and the form validation model changes will be observed.

BREAKING CHANGE:
This commit introduces the notion of "private" properties (properties
whose names begin and/or end with an underscore) on the scope chain.
These properties will not be available to Angular expressions (i.e. {{
}} interpolation in templates and strings passed to `$parse`) They are
freely available to JavaScript code (as before).
Motivation
----------
Angular expressions execute in a limited context. They do not have
direct access to the global scope, Window, Document or the Function
constructor. However, they have direct access to names/properties on
the scope chain. It has been a long standing best practice to keep
sensitive APIs outside of the scope chain (in a closure or your
controller.) That's easier said that done for two reasons: (1)
JavaScript does not have a notion of private properties so if you need
someone on the scope chain for JavaScript use, you also expose it to
Angular expressions, and (2) the new "controller as" syntax that's now
in increased usage exposes the entire controller on the scope chain
greatly increaing the exposed surface. Though Angular expressions are
written and controlled by the developer, they (1) typically deal with
user input and (2) don't get the kind of test coverage that JavaScript
code would. This commit provides a way, via a naming convention, to
allow publishing/restricting properties from controllers/scopes to
Angular expressions enabling one to only expose those properties that
are actually needed by the expressions.
When using ngIf with ngInclude on the same element, ngIf previously did not remove
elements added by ngInclude. Similarly, when using ngIfStart/End, ngIf will miss
elements added between the start/end markers added after ngIf is linked.
This commit changes the behavior of ngIf to add a comment node at the end of its
elements such that elements between the starting comment and this ending comment
are removed when ngIf's predicate does not hold.
Recently we changed the priority of attribute interpolation directive to -100
to ensure that it executes early in the post linking phase. This causes issues
with when terminal directives are placed on elements with attribute bindings
because the terminal directive will usually have 0 or higher priority which
results in attr interpolation directive not being applied to the element.
To fix this issue I'm switching the priority back to 100 and making moving the
binding setup into the pre-linking function.
This means that:
- terminal directives with priority lower than 100 will not affect the attribute
binding
- if a directive wants to add or alter bindings it can do so in the pre-linking
phase, as long as the priority of this directive is more than 100
- all post-linking functions will execute after the attribute binding has been
set up
- all pre-linking functions with directive priority lower than 100 will execute
after the attribute bindings have been setup
BREAKING CHANGE: the attribute interpolation (binding) executes as a directive
with priority 100 and the binding is set up in the pre-linking phase. It used
to be that the priority was -100 in rc.2 (100 before rc.2) and that the binding
was setup in the post-linking phase.

When we re-enter compilation either due to async directive templates or element transclude directive
we need to keep track of controllers to instantiate during linking.
This piece of info was missing when re-entering compilation and that's what this commit fixes.
I also reordered the properties in the previousCompileContext object.

A common mistake for beginners is to attach a controller in both the
$routeProvider and also in the html document using the ng-controller
directive. This change highlights this, to help prevent developers from
doing so in the future.

When we refactored , we broke the csp mode because the previous implementation
relied on the fact that it was ok to lazy initialize the .csp property, this
is not the case any more.
Besides, we need to know about csp mode during bootstrap and avoid injecting the
stylesheet when csp is active, so I refactored the code to fix both issues.
PR #4411 will follow up on this commit and add more improvements.

BREAKING CHANGE: triggering ngCsp directive via `ng:csp` attribute is not
supported any more. Please use data-ng-csp instead.
Issue an error and abort compilation when two directives that ask for transclusion are found
on a single element. This configuration is not supported and we previously failed to issue
the error because in the case of element transclusion the compilation is re-started and this
caused the compilation context to be lost.
The ngRepeat directive has been special-cased to bypass this warning because it knows how to
handle this scenario internally.
This is not an ideal solution to the problem of multiple transclusions per element, we are
hoping to have this configuration supported by the compiler in the future. See #4357.

BREAKING CHANGE: the priority of ngRepeat, ngSwitchWhen, ngIf,
ngInclude and ngView has changed. This could affect directives that
explicitly specify their priority.
In order to make ngRepeat, ngSwitchWhen, ngIf, ngInclude and ngView
work together in all common scenarios their directives are being
adjusted to achieve the following precendence:
Directive | Old Priority | New Priority
=============================================
ngRepeat | 1000 | 1000
---------------------------------------------
ngSwitchWhen | 500 | 800
---------------------------------------------
ngIf | 1000 | 600
---------------------------------------------
ngInclude/ngView | 1000 | 400
Array.prototype.sort is speced out to be as potentionally unstable sort,
which is how it's implemented in FF and IE. This has caused the order
of directives with the same priority to vary between browsers.
For consistency sake, we now consider directive name and registration,
order when determining the order of directives with the same priority.
Note: it is still possible to get into a situation when the directive
order is underministic - when source files are loaded asynchronously
in non-deterministic order and there are are directives registered
with the same name and priority, the order in which they will be applied
will depend on the file load order.
The location service, and other portions of the application,
were relying on a complicated regular expression to get parts of a URL.
But there is already a private urlUtils provider,
which relies on HTMLAnchorElement to provide this information,
and is suitable for most cases.
In order to make urlUtils more accessible in the absence of DI,
its methods were converted to standalone functions available globally.
The urlUtils.resolve method was renamed urlResolve,
and was refactored to only take 1 argument, url,
and not the 2nd "parse" boolean.
The method now always returns a parsed url.
All places in code which previously wanted a string instead of a parsed
url can now get the value from the href property of the returned object.
Tests were also added to ensure IPv6 addresses were handled correctly.
