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.
