Currently, the document entry is created at the first time when some JS code tries to access it. But for the case when server timing headers exist for a document loading channel, we need to create the document entry and save the server timing data in the document entry.
If we don’t do this, the server timing data would be lost since the http channel will be deleted.

This patch was reviewed in parts, however the intermediate states would not build:
Bug 1443954 - Part 3A: Strip pointers from the argument to WriteParam and WriteIPDLParam before selecting the ParamTraits impl, r=froydnj
Bug 1443954 - Part 3B: Move nsIAlertNotification serialization to the refcounted system, r=bz
Bug 1443954 - Part 3C: Move geolocation serialization to the refcounted system, r=bz
Bug 1443954 - Part 3D: Move nsIInputStream serialization to the refcounted system, r=baku
Bug 1443954 - Part 3E: Move BlobImpl serialization to the refcounted system, r=baku
Bug 1443954 - Part 3F: Correctly implement ParamTraits for actors after the ParamTraits changes, r=froydnj
NullPrincipal::Create() (will null OA) may cause an OriginAttributes bypass.
We change Create() so OriginAttributes is no longer optional, and rename
Create() with no arguments to make it more explicit about what the caller is doing.

Currently VarCache prefs are setup in two parts:
- The vanilla pref part, installed via a data file such as all.js, or via an
API call.
- The VarCache variable part, setup by an Add*VarCache() call.
Both parts are needed for the pref to actually operate as a proper VarCache
pref. (There are various prefs for which we do one but not the other unless a
certain condition is met.)
This patch introduces a new way of doing things. There is a new file,
modules/libpref/init/StaticPrefList.h, which defines prefs like this:
> VARCACHE_PREF(
> "layout.accessiblecaret.width",
> layout_accessiblecaret_width,
> float, 34.0
> )
This replaces both the existing parts.
The preprocessor is used to generate multiple things from this single
definition:
- A global variable (the VarCache itself).
- A getter for that global variable.
- A call to an init function that unconditionally installs the pref in the
prefs hash table at startup.
C++ files can include the new StaticPrefs.h file to access the getter.
Rust code cannot use the getter, but can access the global variable directly
via structs.rs. This is similar to how things currently work for Rust code.
Non-VarCache prefs can also be declared in StaticPrefList.h, using PREF instead
of the VARCACHE_PREF.
The new approach has the following advantages.
+ It eliminates the duplication (in all.js and the Add*VarCache() call) of the
pref name and default value, preventing potential mismatches. (This is a real
problem in practice!)
+ There is now a single initialization point for these VarCache prefs.
+ This avoids need to find a place to insert the Add*VarCache() calls, which
are currently spread all over the place.
+ It also eliminates the common pattern whereby these calls are wrapped in a
execute-once block protected by a static boolean (see bug 1346224).
+ It's no longer possible to have a VarCache pref for which only one of the
pieces has been setup.
+ It encapsulates the VarCache global variable, so there is no need to declare
it separately.
+ VarCache reads are done via a getter (e.g. StaticPrefs::foo_bar_baz())
instead of a raw global variable read.
+ This makes it clearer that you're reading a pref value, and easier to
search for uses.
+ This prevents accidental writes to the global variable.
+ This prevents accidental mistyping of the pref name.
+ This provides a single chokepoint in the code for such accesses, which make
adding checking and instrumentation feasible.
+ It subsumes MediaPrefs, and will allow that class to be removed. (gfxPrefs is
a harder lift, unfortunately.)
+ Once all VarCache prefs are migrated to the new approach, the VarCache
mechanism will be better encapsulated, with fewer details publicly visible.
+ (Future work) This will allow the pref names to be stored statically, saving
memory in every process.
The main downside of the new approach is that all of these prefs are in a
single header that is included in quite a few places, so any changes to this
header will cause a fair amount of recompilation.
Another minor downside is that all VarCache prefs are defined and visible from
start-up. For test-only prefs like network.predictor.doing-tests, having them
show in about:config isn't particularly useful.
The patch also moves three network VarCache prefs to the new mechanism as a
basic demonstration. (And note the inconsistencies in the multiple initial
values that were provided for
network.auth.subresource-img-cross-origin-http-auth-allow!) There will be
numerous follow-up bugs to convert the remaining VarCache prefs.

The original code (from bug 1200802) declared an XPCOM object as a static bare
pointer, which for future reference is probably never the right thing to do. It
might have worked if it was cleared before shutdown but it never was.

Older versions of clang complain about this code, with:
netwerk/protocol/http/nsCORSListenerProxy.cpp:230:5: error: default initialization of an object of const type 'const struct CheckHeaderToken' without a user-provided default constructor
Later versions of the standard were amended to make this not an error,
but clang still warns. Pacify clang by making the object not const.
What we're really doing in CacheEntry::CheckRequest is checking:
a) Whether the method is contained in our allowed methods; and
b) Whether all of the headers are contained in our allowed headers.
nsTArray lets us check directly for containing elements, so let's use
that facility rather than rolling our own.
nsCaseInsensitiveCStringComparator ought to be cheap to construct, but
the object actually has a vtable to install and whatnot. So it's
beneficial to pull the construction of it outside of the headers loop.
The entries in mMethods and mHeaders aren't sorted in any special way,
so we can remove expired entries using UnorderedRemoveElementAt, which
is faster than RemoveElementAt.
