Framework: Forward port ADB over network (Part 2 of 2)

Includes:
- ADB Over Network, integration of the adb-host mode (already present)
  The feature can be used/tested without the Settings part:

    setprop service.adb.tcp.port 5555

  Note: This ADB setting is not persistent (for security purpose) and
  require init.rc implementation event like this : http://bit.ly/AdbTcpIP

Improve scrolling cache

Scrolling cache helps make short scrolls/flings smooth but will
cause stutter when long flings are made. This patch disables
scrolling cache when long flings are made.

This patch also fixes a related bug where scrolling cache will
not be enabled properly when transitioning from flinging to scrolling.

Patch Set 2: Calculate threshold based on maximum velocity (Sang Tae Park)

KeyguardSimPinView: don't send dummy request to get remaining pin

I'm not sure of the behavior on QCOM RILs, but on Broadcom RIL
(and probably other RILs), this will eat into the user's PIN
remaining tries. Given that the user is only given ~3 tries, this
is a very bad idea.

In addition, if onAttachedToWindow is called multiple times before
the RIL replies, this can completely delete the retry quota leading
straight to the PUK screen.

Framework: Volume key cursor control (1/2)
