orangefs: revamp block sizes
Now the superblock block size is PAGE_SIZE. The inode block size is
PAGE_SIZE for directories and symlinks, but is the server-reported
block size for regular files.
The block size in the OrangeFS private inode is now deleted. Stat
now reports PAGE_SIZE for directories and symlinks and the
server-reported block size for regular files.
The user-space visible change is that the block size for directores
and symlinks and the superblock is now PAGE_SIZE rather than the size of
the client-core shared memory buffers, which was typically four
megabytes.
