This patch implements the initial Kunit based set of
unit tests for HFS string operations. It checks
functionality of hfs_strcmp(), hfs_hash_dentry(),
and hfs_compare_dentry() methods.

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.

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.

The CONFIG_EXPERIMENTAL config item has not carried much meaning for a
while now and is almost always enabled by default. As agreed during the
Linux kernel summit, remove it from any "depends on" lines in Kconfigs.
