inode_operations.fileattr_(get|set) didn't exist when the various flag
ioctls where implemented - but they do now, which means we can delete a
bunch of ioctl code in favor of standard VFS level wrappers.

This patch implements support for case-insensitive file name lookups
in bcachefs.
The implementation uses the same UTF-8 lowering and normalization that
ext4 and f2fs is using.
More information is provided in Documentation/bcachefs/casefolding.rst
Compatibility notes:
This uses the new versioning scheme for incompatible features where an
incompatible feature is tied to a version number: the superblock says
"we may use incompat features up to x" and "incompat features up to x
are in use", disallowing mounting by previous versions.
Additionally, and old style incompat feature bit is used, so that
kernels without utf8 casefolding support know if casefolding
specifically is in use and they're allowed to mount.

This lets us use bch2_prt_bitflags to print them out.

Initially forked from drivers/md/bcache, bcachefs is a new copy-on-write
filesystem with every feature you could possibly want.
