libmtd: Add support to access OOB available size
This patch exposes OOB available size to user. Then user can use
OOB free area according to OOB available size.
Steps to get OOB available size:
First, access /sys/class/mtd/mtdX/oobavail. If not exist, then
try to get ecc layout by ioctl "ECCGETLAYOUT". If none of them
work, set OOB available size to 0.
