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.
Closes#4409
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.

Issue: multi-elements ng-repeat (ng-repeat-start, ng-repeat-end) can contain elements with a trancluding directive. This directive changes content of the row (template) and ng-repeat does not work correctly (when removing/moving rows), because ng-repeat works with the original template (elements).
This changes ng-repeat behavior to traverse the DOM to find current elements everytime we are moving/removing rows (if the template has multiple elements).
Closes#3104
This reverts commit 3a65822023.
The change cased regressions in third party components that require
promises from getter functions not to be unwrapped.
Since we have deprecated the promise unwrapping support in $parse it
doesn't make much sense to fix this issue and deal with regressions in
third party code.
Closes#4158
This commit disables promise unwrapping and adds
$parseProvider.unwrapPromises() getter/setter api that allows developers
to turn the feature back on if needed. Promise unwrapping support will
be removed from Angular in the future and this setting only allows for
enabling it during transitional period.
If the unwrapping is enabled, Angular will log a warning about each
expression that unwraps a promise (to reduce the noise, each expression
is logged only onces). To disable this logging use
`$parseProvider.logPromiseWarnings(false)`.
Previously promises found anywhere in the expression during expression
evaluation would evaluate to undefined while unresolved and to the
fulfillment value if fulfilled.
This is a feature that didn't prove to be wildly useful or popular,
primarily because of the dichotomy between data access in templates
(accessed as raw values) and controller code (accessed as promises).
In most code we ended up resolving promises manually in controllers
or automatically via routing and unifying the model access in this way.
Other downsides of automatic promise unwrapping:
- when building components it's often desirable to receive the
raw promises
- adds complexity and slows down expression evaluation
- makes expression code pre-generation unattractive due to the
amount of code that needs to be generated
- makes IDE auto-completion and tool support hard
- adds too much magic
BREAKING CHANGE: $parse and templates in general will no longer
automatically unwrap promises. This feature has been deprecated and
if absolutely needed, it can be reenabled during transitional period
via `$parseProvider.unwrapPromises(true)` api.

Changed controller name in example html to ScrollCtrl to match name in example js.
Add styling to example html so scrollable area is not obtrusive to documentation page design.
Closes#3898
`checkboxInputType` and `ngList` directives need to have special logic for whether
they are empty or not. Previously this had been hard coded into their
own directives or the `ngRequired` directive. This made it difficult to handle
these special cases.
This change factors out the question of whether an input is empty into a method
`$isEmpty` on the `ngModelController`. The `ngRequired` directive now uses this
method when testing for validity and directives, such as `checkbox` or `ngList`
can override it to apply logic specific to their needs.
Closes#3490, #3658, #2594
The $interval service simplifies creating and testing recurring tasks.
This service does not increment $browser's outstanding request count,
which means that scenario tests and Protractor tests will not timeout
when a site uses a polling function registered by $interval. Provides
a workaround for #2402.
For unit tests, repeated tasks can be controlled using ngMock$interval's
tick(), tickNext(), and tickAll() functions.
This reverts commit 281feba4ca.
Since Lexer and Parser objects are stateful it is not safe
to reuse them for parsing of multiple expressions.
After recent refactoring into prototypical style, the instantiation
of these objects is so cheap that it's not a huge win to use
singletons here.
Objects received from outside AngularJS may have had their `hasOwnProperty`
method overridden with something else. In cases where we can do this without
incurring a performance penalty we call directly on Object.prototype.hasOwnProperty
to ensure that we use the correct method.
Also, we have some internal hash objects, where the keys for the map are provided
from outside AngularJS. In such cases we either prevent `hasOwnProperty` from
being used as a key or provide some other way of preventing our objects from
having their `hasOwnProperty` overridden.
BREAKING CHANGE: Inputs with name equal to "hasOwnProperty" are not allowed inside
form or ngForm directives.
Before, inputs whose name was "hasOwnProperty" were quietly ignored and not added
to the scope. Now a badname exception is thrown.
Using "hasOwnProperty" for an input name would be very unusual and bad practice.
Either do not include such an input in a `form` or `ngForm` directive or change
the name of the input.
Closes#3331
This reduces memory consumption of parsed angular expressions and
speeds up parsing.
This JSPerf case demonstrates the performance boost:
http://jsperf.com/closure-vs-prototype-ngparser
Chrome: 1.5–2x boost
FF: slightly slower (I would love to know why)
IE: 4x boost
To be clear, this doesn't have any impact on runtime performance
of expressions as demostrated in this JSPerf:

previously the compile/link fns executed in this order controlled via priority:
- CompilePriorityHigh, CompilePriorityMedium, CompilePriorityLow
- PreLinkPriorityHigh, PreLinkPriorityMedium, PreLinkPriorityLow
- link children
- PostLinkPriorityHigh, PostLinkPriorityMedium, PostLinkPriorityLow
This was changed to:
- CompilePriorityHigh, CompilePriorityMedium, CompilePriorityLow
- PreLinkPriorityHigh, PreLinkPriorityMedium, PreLinkPriorityLow
- link children
- PostLinkPriorityLow, PostLinkPriorityMedium , PostLinkPriorityHigh
Using this order the child transclusion directive that gets replaced
onto the current element get executed correctly (see issue #3558),
and more generally, the order of execution of post linking function
makes more sense. The incorrect order was an oversight that has
gone unnoticed for many suns and moons.
(FYI: postLink functions are the default linking functions)
BREAKING CHANGE: the order of postLink fn is now mirror opposite of
the order in which corresponding preLinking and compile functions
execute.
Very few directives in practice rely on order of postLinking function
(unlike on the order of compile functions), so in the rare case
of this change affecting an existing directive, it might be necessary
to convert it to a preLinking function or give it negative priority
(look at the diff of this commit to see how an internal attribute
interpolation directive was adjusted).
Closes#3558
Previously we would stop the compilation for both regular and element
transclusion directives which was wrong. Only element transclusion directives
should be terminal.
