[JFFS2] Core changes required to support JFFS2-on-Dataflash devices.
DataFlash page-sizes are not a power of two (they're multiples of 528
bytes). There are a few places in JFFS2 code where sector_size is used
as a bitmask. A new macro (SECTOR_ADDR) was defined to calculate these
sector addresses. For non-DataFlash devices, the original (faster)
bitmask operation is still used.
In scan.c, the EMPTY_SCAN_SIZE was a constant of 1024.
Since this could be larger than the sector size of the DataFlash, this
is now basically set to MIN(sector_size, 1024).
Addition of a jffs2_is_writebuffered() macro.
