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.
