eCryptfs: update metadata read/write functions
Update the metadata read/write functions and grow_file() to use the
read_write.c routines. Do not open another lower file; use the persistent
lower file instead. Provide a separate function for
crypto.c::ecryptfs_read_xattr_region() to get to the lower xattr without
having to go through the eCryptfs getxattr.
