Add a helper function which checks if an inode is encrypted, and if so,
tries to set up its encryption key. This is a pattern which is
duplicated in multiple places in each of ext4, f2fs, and ubifs --- for
example, when a regular file is asked to be opened or truncated.

Now that all callers of fscrypt_operations.is_encrypted() have been
switched to IS_ENCRYPTED(), remove ->is_encrypted().

Filesystems have to include different header files based on whether they
are compiled with encryption support or not. That's nasty and messy.
Instead, rationalise the headers so we have a single include fscrypt.h
and let it decide what internal implementation to include based on the
__FS_HAS_ENCRYPTION define. Filesystems set __FS_HAS_ENCRYPTION to 1
before including linux/fscrypt.h if they are built with encryption
support. Otherwise, they must set __FS_HAS_ENCRYPTION to 0.
Add guards to prevent fscrypt_supp.h and fscrypt_notsupp.h from being
directly included by filesystems.
