xfs: rename MAXPATHLEN to XFS_SYMLINK_MAXLEN
XFS has a maximum symlink target length of 1024 bytes; this is a holdover from the Irix days. Unfortunately, the constant establishing this is 'MAXPATHLEN' and is /not/ the same as the Linux MAXPATHLEN, which is 4096. The kernel enforces its 1024 byte MAXPATHLEN on symlink targets, but xfsprogs picks up the (Linux) system 4096 byte MAXPATHLEN, which means that xfs_repair doesn't complain about oversized symlinks. Since this is an on-disk format constraint, put the define in the XFS namespace and move everything over to use the new name. Signed-off-by: Darrick J.
