blkdiscard: add new command

blkdiscard is used to discard device sectors. This is useful for
solid-state drivers (SSDs) and thinly-provisioned storage. Unlike
fstrim this command is used directly on the block device.

blkkdiscard uses BLKDISCARD ioctl or BLKSECDISCARD ioctl for the secure
discard.

All data in the discarded region on the device will be lost!
