This patch gets rid of gUsages in LSNG. This provides better consistency and
makes it easier to cache quota info on disk.
The patch also fixes some edge cases when usage was not adjusted correctly after
a failed file or database operation.

This patch wraps the uint64_t type in a Maybe container, so the client usage can
represent a state when there are no files on disk for the given client. Zero
usage then represents a state when there are some files but they are empty or
the client tracks logical size (not physical size of files on disk) and the
logical size is zero. This can be useful especially for LocalStorage.

This patch adds a fixed-size array of client usages to OriginInfo and modifies
quota tracking APIs to require the client type to be passed in.
A new method ResetUsageForClient is implemented. The method is used during
client-specific origin clearing. ResetUsageForClient is much faster than calling
GetUsageForOrigin and calling DecreaseUsageForOrigin after that.
LockedUsage now has an assertion that verifies that the total sum of client
usages matches total origin usage. This method should be called instead of
touching mUsage directly.
A new assertion is added to GetQuotaObject which verifies that passed file
belongs to the given persistence type, origin, and client.

They're infallible in practice and always `NS_OK`. (This stems from
`AddVarCacheNoAssignment()` always returning `NS_OK`.)
As a result, the commit removes lots of unnecessary checks.

LS Request parameters are now verified as part of the state machine so an actor
is always created. Before this patch, we were doing verification prior to actor
creation. If the verification failed, we didn't create an actor and content
was endlessly waiting for a reply.
This patch adds a write optimizer to LSSnapshot. The optimizer is only used when
there are no observers for other content processes.

This patch renames GetSnapshotInitInfo to GetSnapshotLoadInfo and removes some arguments that are not directly related to load info.

This patch renames the Checkpoint IPC message to CheckpointAndNotify. Other structures used by checkpointing are renamed too. Datastore methods SetItem/RemoveItem/Clear no longer call NotifyObservers, it's now up to RecvCheckpointAndNotify to call it.

This patch creates a new generic class LSWriteOptimizer which can be used with any value type for specific write optimizations either on the parent side or the child side.
