XFS: ASCII case-insensitive support

Implement ASCII case-insensitive support. It's primary purpose
is for supporting existing filesystems that already use this
case-insensitive mode migrated from IRIX. But, if you only need
ASCII-only case-insensitive support (ie. English only) and will
never use another language, then this mode is perfectly adequate.

ASCII-CI is implemented by generating hashes based on lower-case
letters and doing lower-case compares. It implements a new
xfs_nameops vector for doing the hashes and comparisons for
all filename operations.

To create a filesystem with this CI mode, use:
# mkfs.xfs -n version=ci <device>

  Add ASCII CI flag and support to superblock
