xfs_dir_canenter and xfs_dir_createname are
almost identical.
Fold the former into the latter, with a helpful
wrapper for the former. If createname is called without
an inode number, it now only checks for space, and does
not actually add the entry.

Move the resblks test out of the xfs_dir_canenter,
and into the caller.
This makes a little more sense on the face of it;
xfs_dir_canenter immediately returns if resblks !=0;
and given some of the comments preceding the calls:
* Check for ability to enter directory entry, if no space reserved.
even more so.
It also facilitates the next patch.

Convert all the errors the core XFs code to negative error signs
like the rest of the kernel and remove all the sign conversion we
do in the interface layers.
Errors for conversion (and comparison) found via searches like:
$ git grep " E" fs/xfs
$ git grep "return E" fs/xfs
$ git grep " E[A-Z].*;$" fs/xfs
Negation points found via searches like:
$ git grep "= -[a-z,A-Z]" fs/xfs
$ git grep "return -[a-z,A-D,F-Z]" fs/xfs
$ git grep " -[a-z].*;" fs/xfs

Move all the source files that are shared with userspace into
libxfs/. This is done as one big chunk simpy to get it done
quickly
