Create a libxfs helper function that marks an inode free on disk.

INIT_XATTRS is overloaded here -- it's set during the creat process when
we think that we're immediately going to set some ACL xattrs to save
time. However, it's also used by the parent pointers code to enable the
attr fork in preparation to receive ppptr xattrs. This results in
xfs_has_parent() branches scattered around the codebase to turn on
INIT_XATTRS.
Linkable files are created far more commonly than unlinkable temporary
files or directory tree roots, so we should centralize this logic in
xfs_inode_init. For the three callers that don't want parent pointers
(online repiar tempfiles, unlinkable tempfiles, rootdir creation) we
provide an UNLINKABLE flag to skip attr fork initialization.

Move all the code that initializes a new inode's attributes from the
icreate_args structure and the parent directory into libxfs.

Callers that want to create an inode currently pass all possible file
attribute values for the new inode into xfs_init_new_inode as ten
separate parameters. This causes two code maintenance issues: first, we
have large multi-line call sites which programmers must read carefully
to make sure they did not accidentally invert a value. Second, all
three file id parameters must be passed separately to the quota
functions; any discrepancy results in quota count errors.
Clean this up by creating a new icreate_args structure to hold all this
information, some helpers to initialize them properly, and make the
callers pass this structure through to the creation function, whose name
we shorten to xfs_icreate. This eliminates the issues, enables us to
keep the inode init code in sync with userspace via libxfs, and is
needed for future metadata directory tree management.
(A subsequent cleanup will also fix the quota alloc calls.)

Hoist the inode flag conversion functions into libxfs so that we can
keep them in sync. Do this by creating a new xfs_inode_util.c file in
libxfs.
