If class A is derived from class B, then an instance of class A can be
converted to B via a static cast, so a slower QI is not needed.

This avoids setting the title a second time when the title and uri remain the same across setTitle calls. This means we can avoid unnecessary history updates which currently result in extra disk i/o.

This also removes the (afaict, unused) stub implementation from TabParent. The netwerk header
inclusions were necessary because those files included TabParent.h and through it,
nsISecureBrowserUI, but now TabParent.h no longer does that.

This patch makes the docshell not to report an error if it is a unknown
protocol error. However, we will still display the error page in this
case.

Create ChromeBrowsingContext and move parent process specific parts
from BrowsingContext there. After that make sure that all
BrowsingContexts created in the parent process is actually
ChromeBrowsingContexts and all BrowsingContexts in the child processes
are BrowsingContexts.

The patch also removes some NS_ENSURE_ARG_POINTER checks from these attributes'
getters. Most of these getters already lack such checks, and as long as the
infallible getters are used a non-null pointer is guaranteed. In the worst case
we'll safely null-crash anyway.
- Move VIEWER_WINDOW from nsISHistory to nsSHistory.
- Mark some C++-only nsISHistory methods as [noscript, notxpcom].
- Add gotoIndex() to nsISHistory so that LegacySHistoryImpl() can be removed.
This patch:
- removes GetTransactionAtIndex(), because getTransactionAtIndex() can be used
instead;
- renames a lot of things;
- updates some comments.
nsISHEntry.index is readonly, but if you pass `true` as getEntryAtIndex()'s
second argument, nsISHEntry.index will be modified. This is pretty gross.
This patch changes `index` so it's not readonly (because it's not!) and removes
getEntryAtIndex()'s second argument.
nsSHistory currently implements nsIWebNavigation, but only three of the methods
are actually used, and the rest call MOZ_CRASH. This patch removes the
inheritance and changes the implementations of those three methods (Reload(),
GetCurrentURI(), and GotoIndex()) to pure C++.
There is one test, bug662200_window.xul, that calls Reload() from JS, which is
no longer possible. Fortunately, nsSHistory::ReloadCurrentEntry() -- which *is*
available from JS -- is similar enough to Reload(0) that it can be used
instead.
(The only difference between Reload(0) and ReloadCurrentEntry() is that the
former triggers the `OnHistoryReload` notification and the latter triggers
`OnHistoryGotoIndex`, which doesn't matter for this test.)
This patch removes the 'ScreenOrientationInternal' type from
dom/base/ScreenOrientation.h and moves it into the
HalScreenConfiguration.h header, renaming it simply to 'ScreenOrientation'
in the process. This has several knock-off effects:
- It allows files that needed ScreenOrientationInternal to include a much
smaller header than before
- It greatly reduces the number of headers pulled in when including Hal.h
- It clarifies the role of the type. The 'Internal' part in the name had
nothing to do with it being part of the implementation. The type was public
and called that way only to avoid clashing with the 'ScreenOrientation'
class. Since we moved it into a different namespace it can be renamed
safely.
- It allows a file that was manually re-declaring 'ScreenConfigurationInternal'
type to use the original one
- Finally this fixes a few files which were missing headers they actually
required but that would still build because unified compilation put them into
units that already had those headers thanks to ScreenConfiguration.h

Expose Chrome only WebIDL to interface with BrowsingContext from
script. The API consists of parent, firstChild and nextSibling
attributes for BrowsingContext, and the browsingContext attribute for
Window.
Correctness improvements:
* UTF errors are handled safely per spec instead of dangerously truncating
strings.
* There are fewer converter implementations.
Performance improvements:
* The old code did exact buffer length math, which meant doing UTF math twice
on each input string (once for length calculation and another time for
conversion). Exact length math is more complicated when handling errors
properly, which the old code didn't do. The new code does UTF math on the
string content only once (when converting) but risks allocating more than
once. There are heuristics in place to lower the probability of
reallocation in cases where the double math avoidance isn't enough of a
saving to absorb an allocation and memcpy.
* Previously, in UTF-16 <-> UTF-8 conversions, an ASCII prefix was optimized
but a single non-ASCII code point pessimized the rest of the string. The
new code tries to get back on the fast ASCII path.
* UTF-16 to Latin1 conversion guarantees less about handling of out-of-range
input to eliminate an operation from the inner loop on x86/x86_64.
* When assigning to a pre-existing string, the new code tries to reuse the
old buffer instead of first releasing the old buffer and then allocating a
new one.
* When reallocating from the new code, the memcpy covers only the data that
is part of the logical length of the old string instead of memcpying the
whole capacity. (For old callers old excess memcpy behavior is preserved
due to bogus callers. See bug 1472113.)
* UTF-8 strings in XPConnect that are in the Latin1 range are passed to
SpiderMonkey as Latin1.
New features:
* Conversion between UTF-8 and Latin1 is added in order to enable faster
future interop between Rust code (or otherwise UTF-8-using code) and text
node and SpiderMonkey code that uses Latin1.
