This patch adds telemetry probes to find out how often the cache wins the race but the entry cannot be used because it needs to be revalidated and we cannot send a conditional request.
The reference cycle is supposed to be removed when HttpBackgroundChannelChild::ActorDestroyed, however this operation
is pending due until HttpChannelChild receives OnStartRequest IPC message. Unfortunately the OnStartRequest IPC message
is dropped because of PContent shutdown procedure. So, the reference removal is never executed, which leaks memory
until content process is terminated.

GetMainThreadEventTarget doesn't label runnable with correct doc group or tab group.
In HttpChannelChild we should replace it with |GetNeckoTarget| in general.
By making mIsTrackingResource atomic, HttpChannelChild::ProcessNotifyTrackingResource can be
further changed to do direct function call without dispatching additional runnable on main thread.

nsIURI.originCharset had two use cases:
1) Dealing with the spec-incompliant feature of escapes in the hash
(reference) part of the URL.
2) For UI display of non-UTF-8 URLs.
For hash part handling, we use the document charset instead. For pretty
display of query strings on legacy-encoded pages, we no longer care to them
(see bug 817374 comment 18).
Also, the URL Standard has no concept of "origin charset". This patch
removes nsIURI.originCharset for reducing complexity and spec compliance.

In order to identify how HTTP OMT is used in user environment, I add a telemetry HTTP_CHILD_OMT_STATS
to record the success and fail reason for each HttpChannelChild.
- "success": OMT request is accepted and the target thread is not main thread.
- "successMainThread": OMT request is accepted but the target thread is still main thread.
- "failListener": OMT request is rejected by the direct listener of this channel.
- "failListenerChain": OMT request is rejected by one of the listener in the listener chain.
- "notRequested": HTTP OMT is not requested by the channel owner.

HttpBackgroundChannelChild::ActorDestroy is always called on STS thread. However OnSocketThread will return wrong
result during shutdown phase. In this case we need to use gSocketTransportService->IsOnCurrentThreadInfallible()
to get correct result. In addition, we should disconnect mChannelChild immediately while ActorDestroy is not
triggered by normal IPDL deletion to release HTTP channel as soon as possible.

Most of the names passed to nsIStringBundle::{Get,Format}StringFromUTF8Name
have one of the two following forms:
- a 16-bit C string literal, which is then converted to an 8-bit string in
order for the lookup to occur;
- an 8-bit C string literal converted to a 16-bit string, which is then
converted back to an 8-bit string in order for the lookup to occur.
This patch introduces and uses alternative methods that can take an 8-bit C
string literal, which requires changing some signatures in other methods and
functions. It replaces all C++ uses of the old methods.
The patch also changes the existing {Get,Format}StringFromName() methods so
they take an AUTF8String argument for the name instead of a wstring, because
that's nicer for JS code.
Even though there is a method for C++ code and a different one for JS code,
|binaryname| is used so that the existing method names can be used for the
common case in both languages.
The change reduces the number of NS_ConvertUTF8toUTF16 and
NS_ConvertUTF16toUTF8 conversions while running Speedometer v2 from ~270,000 to
~160,000. (Most of these conversions involved the string
"deprecatedReferrerDirective" in nsCSPParser.cpp.)

In e10s, a channel created by parent does not have a reliable reference
to the inner window ID that initiated the request. Without that, the
channel must request that the content process log and blocked messages
to the web console. This patch creates a new ipdl interface to pass the
message from the parent to the child process. The nsCORSListenerProxy
also needs to keep a reference to the nsIHttpChannel that created it so
it can find its way back to the child. Additionally, the
HttpChannelParent needs to be propagated when creating a new channel for
CORS.

When racing cache with network and the network wins, we don't reset mAvailableCachedAltDataType. So when the cache entry has been opened and has alt-data then nsHttpChannel::GetAlternativeDataType returns alt-data type, but we're delivering raw response (no conversion are applied) from the network.

It's silly to use prmem.h within Firefox code given that in our configuration
its functions are just wrappers for malloc() et al. (Indeed, in some places we
mix PR_Malloc() with free(), or malloc() with PR_Free().)
This patch removes all uses, except for the places where we need to use
PR_Free() to free something allocated by another NSPR function; in those cases
I've added a comment explaining which function did the allocation.

2. Change FtpChannelChild due to (1) and also don't use SystemGroup to dispatch nsFtpChildAsyncAlert runnable since nsIPrompt may touch js script.
3. Use NeckoTargetHolder::Dispatch to dispatch runnables in nsBaseChannel.
Note that RedirectRunnable should be on main thread, so I changed the code from NS_DispatchToCurrentThread to NeckoTargetHolder::Dispatch.

CachePerfStats gathers performance data for single open, read and write operations as well as the whole cache entry opening. It maintains long term and short term average. The long term average filters out excessive values and it represents and average time for a given operation when the cache is not busy. The short term average represents the current cache speed. By comparing these two stats we know pretty quickly that the cache is getting slower and then we race the cache with network immediately without a delay. Otherwise the delay is based on the average cache entry open time.
This patch makes the following changes to the macros.
- Removes PROFILER_LABEL_FUNC. It's only suitable for use in functions outside
classes, due to PROFILER_FUNCTION_NAME not getting class names, and it was
mostly misused.
- Removes PROFILER_FUNCTION_NAME. It's no longer used, and __func__ is
universally available now anyway.
- Combines the first two string literal arguments of PROFILER_LABEL and
PROFILER_LABEL_DYNAMIC into a single argument. There was no good reason for
them to be separate, and it forced a '::' in the label, which isn't always
appropriate. Also, the meaning of the "name_space" argument was interpreted
in an interesting variety of ways.
- Adds an "AUTO_" prefix to PROFILER_LABEL and PROFILER_LABEL_DYNAMIC, to make
it clearer they construct RAII objects rather than just being function calls.
(I myself have screwed up the scoping because of this in the past.)
- Fills in the 'js::ProfileEntry::Category::' qualifier within the macro, so
the caller doesn't need to. This makes a *lot* more of the uses fit onto a
single line.
The patch also makes the following changes to the macro uses (beyond those
required by the changes described above).
- Fixes a bunch of labels that had gotten out of sync with the name of the
class and/or function that encloses them.
- Removes a useless PROFILER_LABEL use within a trivial scope in
EventStateManager::DispatchMouseOrPointerEvent(). It clearly wasn't serving
any useful purpose. It also serves as extra evidence that the AUTO_ prefix is
a good idea.
- Tweaks DecodePool::SyncRunIf{Preferred,Possible} so that the labelling is
done within them, instead of at their callsites, because that's a more
standard way of doing things.
