If we just update the document pointer and not the inner window id then the request is unusable by any document since both the inner window id and the document pointer must match for it to be re-usable.

ReferrerPolicy gets tossed back and forth as a uint32_t and

webidl file and use consistently in native code.

Similar to bug 1373258 and moz-page-thumb:// URIs, we are getting bitten
by the lack of caching support for non-HTTP channels. This may be
removed once bug 1406134 is implemented.

Summary: Really sorry for the size of the patch. It's mostly automatic
s/nsIDocument/Document/ but I had to fix up in a bunch of places manually to
add the right namespacing and such.
Overall it's not a very interesting patch I think.
nsDocument.cpp turns into Document.cpp, nsIDocument.h into Document.h and
nsIDocumentInlines.h into DocumentInlines.h.
I also changed a bunch of nsCOMPtr usage to RefPtr, but not all of it.
While fixing up some of the bits I also removed some unneeded OwnerDoc() null
checks and such, but I didn't do anything riskier than that.
If an imgCacheValidator object is destroyed without calling
imgCacheValidator::OnStartRequest, or imgRequest::Init fails in
OnStartRequest, we left the bound proxies hanging on an update. Now we
cancel the new request, and bind the validating proxies to said request
to ensure their listeners fail gracefully.
When cache validation is in progress, imgRequestProxy defers its
notifications to its listener until the validation is complete. This is
because the cache may be discarded, and the current state will change.
It attempted to share the same flags with notification deferrals used by
ProgressTracker to indicate that there is a pending notification, but
this has problematic/confusing. Hence this patch creates dedicated flags
for notification deferrals due to cache validation.
imgLoader::ValidateEntry would aggressively determine an entry has
expired, even when the request hasn't yet begun. This is because the
expiration time for the entry was not set unless it was for a channel
which supports caching. Now we set the expiration time for all
channels, and if it doesn't support caching, it just expires at the
current time when imgRequest::OnStartRequest is called. Additionally,
imgLoader::ValidateEntry will not consider the expiration time in the
entry until it is non-zero.
An imgRequestProxy may defer notifications when it needs to block on an
imgCacheValidator. It may also be cancelled before the validator has
completed its operation, but before this change, we did not remove the
request from the set of proxies, imgCacheValidator::mProxies. When the
deferral was completed, it would assert to ensure each proxy was still
expecting a deferral before issuing the notifications. Cancelling a
request can actually reset that state, which means we fail the assert.
Failing the assert is actually harmless; in release we suffer no
negative consequences as a result of this sequence of events. Now we
just remove the proxy from the validator set to avoid asserting.
In order to let necko postpone the load of favicon, we have to set request context ID to the http channel that is created to load favicon.
This patch starts with passing a request context ID to nsContentUtils::LoadImage and makes other necessary changes to set the request context ID to the channel.
This part is mainly to mark the channel as urgent-start if src related
attributes in HTMLImageElement and HTMLInputElement is set and the channel is
open due to user interaction. Unfortunately, we cannot just check the event
state just after creating channel since some loading image tasks will be queue
and execute in stable state. Thus, I store the event state in elements and
pass it to the place where create the channel.

This change moves most of the logic for the threadsafety check into
nsAutoOwningThread, rather than having part of the logic live in
nsAutoOwningThread and part of the logic live in nsDebug.h. Changing
this also forces us to clean up a couple of places that replicated the
logic that lived in nsDebug.h as well.
mTouchedTime is not appropriate for this as it is updated when an image
load re-uses the same imgRequest, especially as it has one second
granularity. A timestamp that is updated every time the backing file is
re-read should work better.
A millisecond granularity timestamp would be preferable, and would be
achievable on most or all supported platforms. But some older
filesystems have timestamp granularity of a second or worse, notably
ext3 and FAT32 (and even ext4 filesytems created with inode_size < 256
bytes, e.g. with 'mke2fs -t small' - see
https://ext4.wiki.kernel.org/index.php/Ext4_Disk_Layout#Inode_Timestamps
for details.)
