mtdutils: move OOB auto-layout into libmtd's mtd_write
With the addition of the the new ioctl(MEMWRITE), we can use the
kernel's internal OOB autoplacement option. It's a cleaner interface and
avoids too much duplication of coding effort.
This patch moves any legacy code (using MEMGETOOBSEL) into a legacy
function in libmtd.c. It's not exactly a "pre-2.6.30" feature, so I'm not
moving it to libmtd_legacy.c.
Now, autoplacement features are only activated if we call mtd_write with
mode == MTD_OPS_AUTO_OOB. This should fix some discrepancies for
nandwrite, where we weren't handling OOB consistently (i.e., we had
different functionality when the kernel did/didn't support MEMWRITE).
But that also means that we now default to using MTD_OPS_PLACE_OOB
instead of AUTO layout. To re-enable autoplacement, we can re-implement
the `--autoplace' option that had previously rotted.
This patch also cleans up a need for an extra OOB buffer in nandwrite.
This has been tested a little in nandsim as well as on SLC NAND flash.
