Allow mapping of raw block devices to partition names
Allow mapping of raw block devices (those without a partition table)
to partition names for first stage mount and ueventd. For example, a
block device `vdb` that contains only an ext4 metadata partition could
be mapped to `metadata` such that /dev/block/by-name/metadata is
created.
The mapping is provided by the `androidboot.partition_map` bootconfig
or kernel command line parameter.
