[PATCH 00/13] erofs-utils: mkfs: introduce rebuild mode

[Jingbo Xu]

Introduce a new rebuild mode merging multiple erofs images generated
from either tarerfs index mode (--tar=i):

	mkfs.erofs --tar=i --aufs layer0.erofs layer0.tar
	...
	mkfs.erofs --tar=i --aufs layerN.erofs layerN.tar

	mkfs.erofs merge.erofs layerN.erofs ... layer0.erofs

or tarerofs non-index mode (--tar=f):

	mkfs.erofs --tar=f -Enoinline_data --aufs layer0.erofs layer0.tar
	...
	mkfs.erofs --tar=f -Enoinline_data --aufs layerN.erofs layerN.tar

	mkfs.erofs merge.erofs layerN.erofs ... layer0.erofs

The rebuild mode doesn't support flat inline datalayout yet.
