Add support for Samsung extended AGPS

The AGPS implementation in the GPS chipset used in some Samsung devices
(i9100, i9300) can make use of the Psc field. Adapt the relevant
functions hiding the changes incompatible with other devices under the
AGPS_USE_PSC #define.

Credit to Qaweck from xda-developers forum for finding the meaning
of the field.

FileUtils: add method to get UUID of a volume

android_os_FileUtils_getVolumeUUID: Fix the incorrect logical for call blkid_get_tag_value.
    There are two problems in here.
  1. For the function blkid_get_tag_value third parameter is should be the device, not the mount pointer, in the MediaPrivader.attachVolume, it will pass the mount path to call this function.
  2. The UUID for device is hex, so call atoi is not right. I think call strtol is better than atoi.
