Make "SD Card removed" notification dismissible if the removed SD Card is not the primary storage

The Galaxy S uses the "external SD Card" as the extended storage
and it the notification should be dismissible as it's okay not
to have it.

Additionally, this patch also not hide the USB storage mount dialog
if the removed storage is not the primary storage

Adjust kernel data stack TCP parameters to optimize performance

Enhance Android MobileDataStateTracker class to identify technology
EVDO rev B separate from earlier releases.  This permits use of
separate TCP buffer size for higher bandwidth technology.

Sensor: Add RotationVectorSensor2

Some ICS apps (namely, Google Maps) expects a rotation vector to be
available. Newer devices, this is provided by either Android's
sensor fusion (requires Gyro) or by hardware sensor fusion (MPL).

Older devices will lack this virtual sensor and compass in Google
Maps will not work. To fix this, we can provide our own rotation
vector sensor by converting the values from the orientation sensor.
(They are basically the same information in different formats.)

Thanks to Unhelpful for the help with related math.

frameworks/base: Fix screen stretch issue for NuPlayer

- Fixes screen not moving to full screen after suspend resume during RTSP
  streaming in landscape mode.
- If there is an incorrect height and width, it saves the video height and
  width and then does the correction to have proper width and height.

Keep track of tetherable USB interfaces in both up and down link states.

USB network interfaces that are present-since-boot are never issued "added"
(or "removed", for that matter) notifications from netd, and thus, are only
discovered by Tethering when their link state changes.  Prior to this
commit, such interfaces were only tracked on change to "up" link state,
even though the interfaces were _not_ removed on changes to "down" state.

On some devices (e.g., epicmtd) a change to "up" state only occurs after
(i) IFF_UP is set on the interface, (ii) the rndis USB gadget function is
enabled, and (iii) a USB cable is connected to another machine.  Since
rndis is enabled immediately before the start of USB tethering, the "up"
state is achieved asynchronously, and often _after_ Tethering looks for a
tetherable interface.  However, "down" state is synchronously reported when
IFF_UP is set, and thus, serves as an effective mechanism to notify
Tethering about the existence of the interface.
Add support for using a custom USB management service.
Add support for USB tethering interfaces that are always present.

Previously, the state machine assumed that the USB tethering interfaces
appear/disappear when reconfiguring USB or changing the USB status. Add
some fallback handling for devices where this isn't the case.
Some fixes for custom USB service handling.
