Adds documentation to CdmaCellLocation get lat/long methods

Adds better documentation to the getBaseStationLatitude() and
getBaseStationLongitude() methods to indicate the units for latitude
and longitude in CdmaCellLocation. Unlike the Android Location API
methods, latitude and longitude in CdmaCellLocation are not in decimal
degrees but instead in 0.25 seconds due to a more obscure 3GPP standard
underlying the Telephony API.  The current Javadocs on the Android
developer page (http://goo.gl/hvWo6) do not indicate the units for
latitude and longitude in CdmaCellLocation, making it very difficult
for developers to interpret the output of these methods, especially
since 0.25 seconds is not a commonly used unit for latitude and longitude
in application-level code.  This patch adds clear documentation to
these methods so developers can clearly understand the units for
latitude and longitude without having to dig through the Android
platform source code.

SystemServer: Looper's getMainLooper to return ServerThread

Fix to ensure Context.getMainLooper and Looper.getMainLooper
returns ServerThread for system_server. Currently, Looper's
getMainLooper returns null.

Adds utility method to convert 0.25 secs to decimal degrees

This patch adds a utility method that converts latitude and longitude
in quarter seconds units to decimal degrees units.  The Telephony API
returns CDMA base station latitude and longitude in quarter seconds
due to a 3GPP telecom standard, while the Android Location API, and
the vast majority of application-level code, uses decimal degrees.

For example, to measure the distance from the user's current location
to the base station using the Location API Location.distanceBetween()
method (http://goo.gl/YjO8O), the base station lat and long would need
to be converted to decimal degrees first.

Since most application developers will likely never use lat/long information
in quarter seconds units, and instead will need this information in decimal
degrees, this utility method will frequently be used by anyone querying
base station location data from CdmaCellLocation.

Sample values to test conversion:

0.25 seconds: lat = 399491, long = -1189145
is equivalent to
decimal degrees: lat = 27.742430555555554, long = -82.57951388888888

Avoid memory leak in the Shutdown confirmation dialog.

How to reproduce:
1) Lock the screen.
2) Open the Phone options menu by long pressing the power
   button.
3) Tap "Power off" to display the confirmation dialog.
4) Repeat step 2 and 3 a few times (without closing the
   confirmation dialog.

Each time the confirmation dialog is displayed, a new
instance is created. A stack of confirmation dialogs are
created on the screen.

This is fixed by making sure the previous dialog is
dismissed before launching a new dialog.

stagefright aacenc: Move system headers before local headers

This avoids issues with the encoder's own definition of __inline,
which conflicts with headers brought in by string.h in glibc.
