fs/jfs: Use common ucs2 upper case table

Use the UCS-2 upper case tables from nls, that are shared
with smb.

This code in JFS is hard to test, so we're only reusing the
same tables (which are identical), not trying to reuse the
rest of the helper functions.

fs: add CONFIG_BUFFER_HEAD

Add a new config option that controls building the buffer_head code, and
select it from all file systems and stacking drivers that need it.

For the block device nodes and alternative iomap based buffered I/O path
is provided when buffer_head support is not enabled, and iomap needs a
a small tweak to define the IOMAP_F_BUFFER_HEAD flag to 0 to not call
into the buffer_head code when it doesn't exist.

Otherwise this is just Kconfig and ifdef changes.

fs: build the legacy direct I/O code conditionally

Add a new LEGACY_DIRECT_IO config symbol that is only selected by the
file systems that still use the legacy blockdev_direct_IO code, so that
kernels without support for those file systems don't need to build the
code.
