* changes:
  Add ION usage into dumpsys report and account ION pools as kernel cache
  Improve cached kernel memory accounting using meminfo KReclaimable field
  Add JNI API to query sizes of ION heaps, pools and mapped part of the heaps

Report ION pools, ION mapped and unmapped heap sizes. Account ION pools
as kernel reclaimable memory which removes them from the "Lost RAM"
category.

KReclaimable field from /proc/meminfo is designed to represent total amount
of memory that kernel can reclaim when needed. This includes reclaimable
memory consumed by slab and reported in SReclaimable field as well as ION
pools. By using KReclaimable instead of SReclaimable we will account for
ION pools currently reported under "Lost RAM" category in dumpsys meminfo
report.

Provide means for system_server to query ION memory usage. The new API
allows to get total size of ION heaps, pools and part of ION heaps that
is mapped into user space.

The module framework is now a build-only library whose purpose is to
provide hidden APIs from the non-updatable part of the platform and APIs
from the modules. Merging updatable_media_stub to framework, like the
stub libraries from other modules.

Such checks uses old libvintf to parse new VINTF metadata, which is not
supported. The check is now moved to OTA package build time, so there is
no need to check it on the device.

ModemActivityInfo is used for batteryStatusService which is part of
system service. To prepare telephony to be an mainline module, we
should expose ModemActivityInfo to systemAPI

1. remove getConsumedPower API as we are missing modem support, API
today only report 0
2. isValid API is introduced to cover modem issues before. Do not
expose this for now.
