Frozen flex items have already been clamped to their min/max sizes, so their
size-change isn't a "how much we want to flex" measurement, and it's not useful
for determining whether the rest of the line is shrinking.
This patch is just adding a `if (!item->IsFrozen())` check around some code,
and reindenting that code, and adjusting a few comments.
This change is necessary to avoid failing the "GrowthState" assertions,
because (for example) a flex item that's clamped to a small max-width
could fool us into thinking we're in a "shrinking" state (since its final
size is smaller than its base size), even though really we're
in a "growth" state and the item was simply clamped. We avoid this
problem by skipping (potentially-clamped) frozen items when determining
the line's GrowthState.

We'd like to be able to record the "desired" (pre-clamped) delta size from
tentatively flexing for these items. That size would be computed during a loop
of the flex layout algorithm -- but we can't do that if we freeze them before
we start flexing. So let's bypass this early freeze so they get a chance to
compute this tentative size, even though they can never have it.

This refactor does a few things:
1. Unifies the composition of the GeckoBundle, so that some tricky edge
cases don't need to be implemented twice.
2. Allows us to be more frugal with round trip sync ipc calls. Instead
of retrieving everything from the start, only progressivley retrieve
what we need.
3. Sets the groundwork for the next patch that will return from this
function earlier with a smaller bundle.

Creates the nsDocShellLoadState object, which is basically
nsDocShellLoadInfo plus a few extra fields to make it usable as a
single argument to nsDocShell::LoadURI (and eventually
nsDocShell::InternalLoad).
Subframe history handling is a huge logic block in
nsDocShell::LoadURI, which is only used on history loads. This patch
also extracts the logic out into its own function to make the body of
LoadURI clearer.

The Webrender Pref Experiment is reporting its pref via telemetry and that is
reporting a different value than what the Normandy experiments telemetry
indicates should be being seen.
In Bug 1499552 I added a pref and telemetry reporting in preparation for running
a dummy Pref Experiment to verify that prefs set are reported as set, but I
realised I missed a case; where there's an existing default pref set,
we're only covering the case where that default pref has value false. We're seeing
a ~25% failure rate in the pref reporting. So we should cover the other three cases
in the dummy Pref Experiment, just in case it's one of these four cases that
is failing.
So here I add another dummy pref with a default value of true, and I report that
via telemetry. I rename the pref I added yesterday to make things consistent.

The known web element cache in the WebDriver test client, or
webdriver.Session._element_cache, is used only to avoid constructing
new webdriver.Element instances of the same web element and serves
no practical purpose beyond that
Since this client is intended for testing purposes, we would like
to be able to construct duplicate webdriver.Element instances,
so that e.g. fake elements can be constructed and send to the remote end.

Before this patch, Necko functions polling the state of TLS sockets
(essentially, TransportSecurityInfo) would cause a considerable amount of
locking on TransportSecurityInfo::mMutex instances via GetErrorCode(). Most of
this code only cared if an error had been set via SetCanceled(), so this patch
adds an atomic boolean mCanceled (and associated accessor GetCanceled()) that
can be used to the same effect but without acquiring the lock.

Iterating an IDB cursor generates a lot of overhead. In this patch, we upgrade the kinto-offline to its latest version that uses `getAll()` when no filter is specified. We leverage this change in tippytop, by omitting the filter and filtering the whole list there instead. This allowed us to go from ~1sec on a 1000 entries to ~70ms.

In the current code there are 3 main issues:
1. nsFileStream is not really thread-safe. There is nothing to protect the
internal members and we see crashes.
2. nsPipeInputStream doesn't implement ::Seek() method and that caused issues
in devtools when a nsHttpChannel sends POST data using a pipe. In order to fix
this, bug 1494176 added a check in nsHttpChannel: if the stream doesn't
implement ::Seek(), let's clone it. This was an hack around nsPipeInputStream,
and it's bad.
3. When nsHttpChannel sends POST data using a file stream, nsFileStream does
I/O on main-thread because of the issue 2. Plus, ::Seek() is called on the
main-thread causing issue 1.
Note that nsPipeInputStream implements only ::Tell(), of the nsISeekableStream
methods. It doesn't implement ::Seek() and it doesn't implement ::SetEOF().
With this patch I want to fix point 2 and point 3 (and consequentially issue 1
- but we need a separate fix for it - follow up). The patch does:
1. it splits nsISeekableStream in 2 interfaces: nsITellableStream and
nsISeekableStream.
2. nsPipeInputStream implements only nsITellableStream. Doing this, we don't
need the ::Seek() check for point 2 in nsHttpChannel: a simple QI check is
enough.
3. Because we don't call ::Seek() in nsHttpChannel, nsFileStream doesn't do I/O
on the main-thread, and we don't crash doing so.
Instead of creating a timer and then setting the timer's target, we can
determine the timer's target and pass it in directly when the timer is
created. This reordering of steps is slightly more efficient, since
SetTarget() is both a virtual call and requires locking, both of which
can be skipped if we know the target at timer creation time.
When sending a command to the server, a timestamp is
computed before evaluating the string, and is then
sent back to the client in the packet.
However, if top-level await, or somme :commands, the
evaluation takes more time, which means the timestamp
is now innacurate.
For those cases, we update the timestamp before sending
the packet to the client.
