This series adds a nand write variant which implements the procedure reccomended in the UBI FAQ [1] of dropping trailing pages of eraseblocks containing entirely 0xff's.

Changes since v2: * dropped WITH_DEFAULTS in favour of '0' * moved copyright header to nand_util patch * added write.trimffs variant to README.nand
Changes since v1: * renamed to 'trimffs' from 'ubi' * wrapped the new feature in #ifdefs * don't make it default for jffs -- patch dropped * attribution of the drop_ffs() function from mtd-utils to Artem
