Original description:

(This was initially described in #6963)

Our current design to is implement "processing" signals on Folder, Account,
and Engine. The common signal parameters are a notification type (Background
Sync, Database Update, Search Processing, Sending Email, Connecting, and a
generic Activity notification), a state enum (Start, Progress, Stop), a
percentage field of some kind for Progress, and a tag to indicate
Start/Progress/Stop pairings.

In addition, each container (Account, Engine) aggregates the objects it holds
as a convenience to the client. Thus, the Account "processing" signal includes
a nullable Folder parameter, and the Engine "processing" signal includes a
nullable Account parameter. (It's possible in the future Engine will do its
own background processing.)

Since some of these notifications can come in parallel, each object in the
heirarchy will have a ProcessingTracker which does the bookwork of tracking
pairs and supplying relevant information, i.e. the number of active processes
per type, the aggregate percentage per type, and maybe even an overall
aggregate percentage and a simple boolean "is_processing" field.

With this in place, the client can then get specific information about what
objects are busy (Account, Folder, #4654) as well as a simplified result
("is_processing") for the current spinner (#4644), while not precluding other
indicators where displaying a percentage is desireable (during the search
upgrade, which is what this ticket covers). This system is flexible enough
that all background processing can report their status at any time.
