strict check of extended attribute flags while opening a striped file
Added a fd_ctx structure for stripe, which takes care of understanding the extended attribute flags, and opening the right blocks in order (to make sure the read/write operations happen in order). Helps to handle situations like accidentally adding subvolumes to stripe, etc Signed-off-by: Anand V. Avati <avati@dev.gluster.com>
