CacheFile::OnChunkRead and CacheFile::OnChunkWritten now correctly handle discarded chunks. It's now also ensured that the chunk which is going to be discarded isn't references by any input stream.
Adds nsISubstitutionObserver so that substitutions set on a
parent nsISubstitutingProtocolHandler which are then propagated
to child processes can be observed in the child.
Updates test_extensionURL.html to set substitutions on the parent
ExtensionProtocolHandler before trying to load moz-extension URI's
using those substitutions.

Changes ExtensionProtocolHandler to use remote streams for
moz-extension loads of file and JAR URI's to allow for
filesystem read-access sandboxing.
Adds messaging to PNecko to allow child processes to
request an input stream or file descriptor for moz-extension
URI's.
Add ExtensionProtocolHandler singleton so that NeckoParent can
call methods directly and ExtensionProtocolHandler::NewFD
can use a new member variable |mFileOpenerThread| to open files.
Adds FileDescriptorFile, a limited implementation of nsIFile
that wraps a file descriptor, to be sideloaded into
nsJARChannels so that extension JAR files can be read
using a file descriptor without accessing the filesystem
directly.

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.

SpecialPowers.loadChromeScript() sends a script to the child process,
then creates a sandbox, and runs the script in that sandbox. There are
various sandboxOptions that can be passed when creating a sandbox, and
it would be nice to have that functionality for loadChromeScript.
I just need this for wantGlobalProperties, but I might as well make it
as general as possible. I'm not sure all of the types it can take can
actually be serialized across processes, but I guess that's okay.
