EventHub: Modify the keyboard layout file name for headset button

The keyboard layout file name was formed based on the name of
tabla sound card on current machine. If it doesn't find such
file, it is going to use Generic keyboard layout where the
key mappings are different, even though the scan code is same.
The sound card name differs across different machine types.
So, generalising the keyboard layout file name will work across
all machine types.

frameworks/base: Fix for headset switch detect

- Headset Switch detect is not functional
- Headset driver on modem in 8x25 and 7x27A targets
  introduces a delay of 500ms before reporting headset
  events to application processor to avoid the problem
  of spurious interrupts being reported due to hardware
  limitation on these targets. Frameworks code in JB
  treats button release event received after 500ms after
  button press as long press event and generates WEBSEARCH
  event. Due to this all the events in 8x25 and 7x27A
  are interpreted as long press events.
- To avoid this problem increase the timeout to more than
  500ms by introducing headset hook delay property for
  these targets.

frameworks/base: Fix for UI freeze issue with headset insert/removal

- UI freeze is observed while quick insertion and removal of headset
  for multiple times.
- notifyJackSwitchChanged() acquires mHeadsetLock and waits on
  phoneWindowManager lock to call update() as it is a synchronized
  function. sendIntents() is also "synchronized". This function also
  tries to acquire mHeadsetLock. So there is a dead lock, when the
  notifyJackSwitchChanged() acquires the mHeadsetLock before this
  function does.
- update() is called only from notifyJackSwitched() and need not be a
  synchronized function. Removed synchronization on the update() to
  fix the issue.

UMS support with any volume, not only primary (2/3)

This patch enables UMS support when any volume supports it, even when the
primary storage doesn't.

1. Vold: assign lun_numbers sequentially to the volumes being added to the
   VolumeManager.
2. Fix portions of code which assume that the device has UMS support iff the
   primary storage supports UMS.
   Instead, determine whether the device supports UMS by checking each volume.
3. Display the UMS option in Settings.apk when any volume supports it.

Revert "Framework: Fixes mms automatic retrieval (2/2)"

This reverts commit 1b94dd84424efdaaaeb67cf85118880f200e52b8.
Mms auto-retrieval (2/3): framework

- TelephonyProperties.java: creates new properties "persist.mms.auto_retrieval"$
"persist.mms.auto_on_roaming"
- GsmDataConnectionTracker.java: sets logic for allowing mms data connections
depending on the above properties
- PackaManagerService.java: sets shared user "android.uid.mms" to value MMS_UID
which has the same value as AID_MMS in android_filesystem_config.h

Patchset 1: Initial commit
Patchset 2: Fix braces formating at canSetupData()
Patchset 3: PackageManagerService.java
