This way they don't immediately destruct. Also
up the logging for an allocation failure and use
posix_madvise to possibly improve memory performance.

Test: Transfer files and verify that allocs are scoped properly

when playing multimedia file, GenericSource::getTrackInfo run in the
NuPlayerDriver thread, and GenericSource::getFormatMeta run in the
Generic thread. they would access the critical resource which is
mMetaData in IMediaSource. There is no lock to protect mMetaData.
Occasionally, SIGSEGV occurs when mMetaData point to a new object.

Instead getting trackInfo in Generic thread.

Protect the Audio Policy Manager by adding extra checks
for data.readCString() strings when parsing / decoding
a Binder transaction.

Also:
 * Moved audio_is_output_device() / audio_is_input_device() checks
   inside handleDeviceConfigChange()
   from the AudioPolicyInterface to the AudioPolicyManager
 * Removed similar redundant checks inside
    AudioPolicyService::setDeviceConnectionState()

Test: code compilation

The ioctl preallocates kernel buffers for the read/write syscalls,
reducing memory fragmentation and allowing for larger buffers,
as well as removing the kmalloc overhead.

* Since system/bt depends on this library, it needs to be converted to
  Android.bp before the conversion in system/bt can be continued.
* Majority of work is done by androidmk Android.mk > Android.bp
* Fixed sanitize arguements
* Removed LOCAL_EXPORT_C_INCLUDE_DIRS as Android.bp only supports
  exporting sub-directories of current Android.bp file
* Removed frameworks/av/media/libmedia/aidl include path as it no longer
  exists and Android.mk failed to check that
* Removed include path for audio-utils as it is being automatically
  included when we link against libaudioutils
* Android.mk file must be deleted as a library of the same name can only
  be defined once in either Android.bp or Android.mk
* A library defined in Android.bp can be used by either Android.bp or
  Android.mk files. However, a library defined in Android.mk cannot be
  used by Android.bp file. Therefore, for system/bt to link against this
  library in the Android.bp, this library must be converted first

MPEG4Write mdhd duration of AV track is larger than INT32_MAX
after record over 15 hours, so write mdhd box as version 1 type
which enhance duration to 64 bit.

* Added new call handleDeviceConfigChange() to the Media Framework.
  That call can be used when there are device configuration changes
  (e.g., Bluetooth A2DP codec configuration has changed).
* Added new method AudioPolicyManager::handleDeviceConfigChange().
  That method toggles the UNAVAILABLE/AVAILABLE connection state of the
  device, so it can be reconfigured as appropriate - e.g., the audio
  feeding parameters can be updated.
* Fix ALOGVV compilation errors when extra logging is enabled.

From code analysis, we should make sure that M3UParser::initCheck
returns OK then perform hash memcpy. This would prevent NuPlayer from
overlooking a malformed M3U8 and crashing later on a NULL derefernce.

opposite order, so dumpsys could mix up the format and active
state for a given track. Also fix potential NULL pointer dereference.
