[PATCH]erase count tracking in JFFS2

[zhao forrest]

Hi,

Here I port my original patch to make it adapt
to eraseblock header.
Since EBH has include erase count, part of erase count
tracking work has been done in EBH patch.
The main functionality of this patch is to record
max_erase_count, and assign the average erase_count
to blocks, which has no EBH previously.

The patch is at:

Thanks,
Forrest
