libblkid: store only canonical devnames to the cache
Let's try to use symlink:
# ls -la /dev/block/8\:1
# lrwxrwxrwx 1 root root 7 May 25 16:42 /dev/block/8:1 -> ../sda1
# blkid /dev/block/8:1
/dev/block/8:3: LABEL="HOME" UUID="196972ad-3b13-4bba-ac54-4cb3f7b409a4" TYPE="ext4" PARTUUID="6073277f-87bc-43ff-bcfd-724c4484a63a"
unfortunately the symlink is stored to the cache:
<device DEVNO="0x0803" TIME="1464253300.715279" LABEL="HOME" UUID="196972ad-3b13-4bba-ac54-4cb3f7b409a4" TYPE="ext4" PARTUUID="6073277f-87bc-43ff-bcfd-724c4484a63a">/dev/block/8:3</device>
next time if you ask for LABEL=HOME the answer will be /dev/block/8:3
rather than /dev/sda3.
It seems better to canonicalize the paths we store to the cache.
Unfortunately if you ask for /dev/block/8:3 then you probably expect
that blkid_dev_devname() returns the same path. This patch introduces
dev->bid_xname, this is the path used by application (and never stored
in the cache).
