audio: Fixed dead lock in AudioService during volume change

- AudioService goes into dead lock when there is a volume
  change for source stream and the respective aliased stream
  simultaneously from multiple threads
- When setIndex is called for source stream, it also updates
  the index for the aliased streams. Meantime, setAllIndexes
  is called on aliased stream. Initially, it gets index of
  default device of source stream. It requires lock on the
  source stream. This is leading to a dead lock
- Fix is to avoid locking parent while updating child
  streams. Removing lock from method and synchronizing
  parent only when it is updating member variable.

audio: Inform audio HAL if it is a voice call initiated by Telephony

setMode() API with IN_CALL mode can be called by any of the Apps.

or not. Inform to audio HAL if it is a voice call by checking

Common: Add the api to parse the string to current language

These APIs are used to parse the text to local languange.
For example, if the carrier name in English is got from network or SIM card, we will
use these APIs to parse it to local language and display it to the user.

Fix the texture ID reuse issue in HWUI.

Issue: When the layer of previous frame is destroyed, it doesn't clear the
texture id in mBoundTextures[mTextureUnit], so in the next frame, if
glGenTexture returns same texture ID of the previous frame,
the new texture is not bound.
