This patch mainly whitelist all the dot-files in the persistence directories and
origin directories. Ignore dot-files was first proposed in
Bug 944918 comment 39. ".desktop" was also mentioned in that comment Besides,
"desktop.ini" was first mentioned in Bug 944918 comment 42, "Thumbs.db" was
mentioned in 1493262 comment 11, and "Desktop.ini" was first mentioned
Bug 1423917 comment 46.Thus, this patch also whitelist them all during
initialization.

This patch uses nsLiteralCString instead of nsCString for avoiding increasing
the number of static constructors. Also, it removes the declaration of
kInternalError and kExternalError on Beta and Release since they won't be use
in these channels.

This patch uses categorical keyed Historgram to collect data. While the key is
used to determine whether is it an external error or an internal error (Note:
the external error is referred to low level failure, for example: database
corrupt, OS API errors, ... etc; the internal error is referred to errors, like:
not handle file properly, unexpected filenames, ... etc), the labels for
categorical indicates where the error happens.
Furthermore, this patch make QuotaManager keep traversing the profile even if
an error happens so that we can get more information in the telemetry data.
Please note that these things should only happen in the Nightly Channel.

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.
This patch was enhanced by asuth to bind attached database path.
Places has shown that argument binding is necessary. (Profiles may include usernames in their path which can have cool emoji and such.)
Datastores are preloaded only for content principals. The preloading is triggered as soon as possible to lower the chance of blocking the main thread in content process. If there is no physical database on disk for given origin, datastore is not created. Preloaded datastores are kept alive for 20 seconds.
New methods open() and close() are added to the Storage WebIDL interface. They are only available when a pref is set and are only intended for testing. There's also a new method resetStoragesForPrincipal() which is used as a callback for close() since datastores don't release directory locks immediately. resetStoragesForPrincipal() requests an exclusive lock for given origin, so it must wait for any exising shared locks to be released.
Expose the nested main event target, so it can be used in the single process case by the parent side to process runnables which need to run on the main thread.
After this change we don't have use hacks like getting profile directory path on the child side and sending it to the parent. The parent side can now do it freely even in the single process case.
This patch was enhanced by asuth to not tunnel the nested main event target through IPC.
Preparation of datastores now creates real database files on disk. The LocalStorage directory is protected by a directory lock.
Infrastructure for database schema upgrades is in place too.
Database actors are now explicitely tracked by the datastore. When the last actor finishes the directory lock is released.
Added also implementation for QuotaClient::GetUsageForOrigin() and QuotaClient::AbortOperations().
This adds a new quota client implementation, but only implements ShutdownWorkThreads.
At shutdown we wait for all running operations to finish including database actors which are closed by using an extra IPC message which avoids races between the parent and child.
Databases are dropped on the child side as soon as they are not used (e.g. after unlinking by the cycle collector).
