We are investigating replacing make_ext4fs with the upstream tool mke2fs.
See b/23686092 for more informations.
To mitigate the trouble that may arise if the new tool behave differently
compared to the old one, there will be a transition period where both mke2fs
and make_ext4fs will be supported.
This patch does 3 things:
- add the necessary code to use mke2fs to format an ext4 partition;
- add a dependency to the binary used by vold.
Test: m -j32 with TARGET_USES_MKE2FS={,false,true}
TARGET_USERIMAGES_USE_EXT4={,true}

Changing the num_sectors used in ioctl with BLKGETSIZE because
the kernel expects an unsigned long type and then changes 64 bits
with a 64 bits userspace. This overwrites what's located close to
the parameter location if any.

When formatting volumes, pass along fsType string which can be "auto"
to let the volume select the best choice. For now, private volumes
assume that MMC devices (like SD cards) are best off using f2fs when
both kernel support and tools are present, otherwise fall back to
ext4. Use blkid when mounting to pick the right set of tools.
Move filesystem utility methods into namespaces and place in separate
directory to be more organized.
