Previously the SessionHistoryInfo would hold onto and hand out the
original nsIInputStream objects which were provided by the
nsDocShellLoadState and used to create the underlying channel. This
could cause issues in edge cases, as input streams when serialized over
IPC have their logical owner transferred to the IPC layer so that it can
copy the data to the peer process.
This patch changes the logic to instead clone the input stream to and
from the history info. This means that the history info has its own
instance of the stream type and interacting with it shouldn't interfere
with other consumers of the post data stream.
The behaviour for non-SHIP session history is not changed, as it doesn't
serialize the relevant streams over IPC in the same way, and is on track to be
removed.

For desktop this should basically have no impact (maybe impacts tab
warming, but if we wanted we could set the priority hint from the tab
switcher the same way we set renderLayers), but Fenix always has
renderLayers as true, effectively, so we were never de-prioritizing the
background tab processes.

Currently only same origin requests are preloaded and preloads in the
secure context. This may change in the future to match W3C decisions and
Chromes behavior.
Also only images get preloaded. This will change in the future to cover
asset types.
Currently the anchor isn't parsed correctly yet[1], so this will be
fixed in a future patch.
On non-2xx responses of the main document all ongoing preloads get
canceled. Already completed preloads don't get affected and are in the
cache.
It is currently untested whether unused preloads don't have side effects.
Another future patch should cover adding the preload to the devtools.

This clarifies some of the members and arguments which were used in
DocumentLoadListener to make them more clear, adding documentation.
In addition to the simplifications of logic and improved naming, this
patch also moves the responsibility of managing StreamFilterRequest out
of DisconnectListeners so that stream listeners behave more
consistently, as the existing flag doesn't map well to whether or not
they should be cleared.
This was kept seperate from part 1 as it is largely a clarity
improvement, and may make it harder to see the important changes in that
part.

This patch changes how we handle document loads which are being handled
internally but have Content-Disposition: attachment specified at the
DocumentLoadListener layer. This was done as process switching is
currently the only place during a load where we can change the target
BrowsingContext which the load will complete in.
The only situation where we should currently continue to deliver a
successful request to the default content-viewer despite
Content-Disposition: attachment being specified is when we choose to
handle a downloaded PDF internally, so this shouldn't impact other
cases.
The change is handled by forcing a process switch under the hood, and
opening a new browser window asynchronously to handle the process
switch, similar to how object and embed load upgrades are handled. This
is done using nsIBrowserDOMWindow to attempt to respect the user's
window opening preferences.
A small change to browser.js was also made to try to encourage the new
tab to be opened next to the previous tab, as well as to avoid starting
unnecessary new processes when creating the new browser window.

essentially just added an unnecessary layer of complexity/indirection to the

This property defaults to false. When set to true, user-initiated link clicks in
the top-level BrowsingContext will default target to _blank. This is similar to what
we do for App Tabs, but is slightly more aggressive in that in will also occur for
same-origin navigations.

Before this patch, nsISiteSecurityService APIs took "flags" parameters that
differentiated private contexts from not private contexts. However, these
parameters were redundant with respect to origin attributes, which led to some
confusion for consumers of these APIs. This patch removes these parameters in
favor of using origin attributes.

This allows popups and sidebars to use the chrome preferred
color-scheme.
This moves the responsibility of setting the content-preferred color
scheme to the appropriate browsers to the front-end (via tabs.css).
We still return the PreferredColorSchemeForContent() when there's no
pres context (e.g., for display:none in-process iframes). We could
potentially move a bunch of the pres-context data to the document
instead, but that should be acceptable IMO as for general web content
there's no behavior change in any case.

This patch replaces the previous process selection infrastructure with a
new setup implemented entirely in C++, which should more accurately
track the set of processes in use, and should encourage re-use of the
existing content process when navigating by not counting the current
tab.
This approach intentionally allows for process switching to another
process during navigation if there is uneven load between processes to
encourage balanced process use.
I think this may also fix some of the session restore issues with many
tabs using the same process, rather than being spread over 4, as we now
track a tab earlier in its lifecycle before the BrowserParent instance
is created.

In the case where the triggering principal doesn't exist, calling
nsDocShellLoadState::MaybeStripTrackerQueryStrings() will crash. It's
becuase we will access the triggering principal in the function.
The patch makes the function to return early if the triggering prinicpal
doesn't exist. In this case, we cannot decide if we need to strip the
URL because the information from the triggering principal is lacking.
Therefore, we can only return and don't strip the URL. Also, this can
avoid crashing Firefox.
