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.

The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.

This also requires changing XMLHttpRequest so that it doesn't crash if
memory-mapping would be applicable but the channel has no associated
nsIFile; a regression test for that case is added.
Bonus fix: nsJARChannel::AsyncOpen now checks whether the inner channel's
AsyncOpen failed.
Avoid potential file locking issues by not keeping references to the input
stream in the first place, analog to how nsBaseChannel/nsFileChannel are
implemented. The file locks will now be released as soon as either the stream
is explictly closed or the stream instance gets destroyed.
This means that a synchronous ::Open() will transfer the input stream
ownership to the caller, while asynchronous ::AsyncOpen() will transfer it to
the pump handling the asynchronous transfer to the caller's listener.
