This file was originally added on the release-ios-v3.1.0 branch, before #3913 merged ios/ into platform/ios/. When the release branch was merged back into master in 17f44d7bd9, the file was left in the old ios/ directory.

This change makes background data gathering more efficient by disabling
standard location updates when the device has been stationary for at
least five minutes. It also establishes region monitoring and
significant location change monitoring so that if the device appears to
be in motion again then background telemetry data collection can resume.
All of this reduces the amount of time required for telemetry data
collection to the time the device is in motion only. It also only
applies to host apps that already run in the background and have the
always location permission from their users.
This also includes some changes to make the internal pause/resume API of
the MGLMapboxEvents class less complex and autonomous. The side effects
of the map view waking or sleeping are no longer required for mapbox
events to work as intended.

If the server keeps sending replies considered from the client in the
past (there is no way to tell if the server or client clock is wrong),
the client will try to interpolate a valid expiration time based
on the delta of the expiration intervals sent by the server.
If the intervals are always the same, exponential backoff kicks in
until we get a different expiration time from what we already have.
When we receive an expired tile, we don't immediately retry
because in case the server keeps serving an expired tile, that
would cause an infinite retry cycle.
Now we add an exponential delay, similarly to what we do for
connection errors.

This introduces a new utility class that wraps networking via
NSURLSession. All related code that used to live inside the telemetry
MGLMapboxEvents class has been pulled into the new MGLAPIClient.
An API client instance is used as a service by telemetry and can be
reused in the future when and if our networking needs grow or become
more complex.
SQLite REPLACE is *not* UPSERT. If a conflict occurs, it first deletes the existing row, then inserts a new row. This means that AUTOINCREMENT primary keys change. This will break foreign keys to that value, which we use.
Instead we must try an UPDATE, and fall back to an INSERT if the UPDATE changes zero rows.
Coverage compiler and linker flags are used only when (1) in debug build
and (2) with ENABLE_COVERAGE set to 1. Besides, because OS X's libtool
is unable to understand '--coverage', this linker flag is only used
genrating executable targets. Also, using 'link_settings' to specify
linker options and separate instructions for OSX and Linux.
The last map object to get destroyed will also destroy
the RunLoop (which will also destroy the AsyncTask).
This will clear any reference to the Node default main
loop and let it close.
Downside is that we need to make sure we are always calling
`map.release()`.
The run loop will be kept alive because it has an `AsyncTask`. We
also can simple stop the loop with `uv_stop()`.
The `RunLoop` is still gonna be the last object to be destroyed
because it is the first object to be created in the thread, so
by design it won't outlive `Timer`s and `AsyncTask`s.
This patch won't change the current behavior, will just make
the code simpler.
