Adding an extended attribute to a symbolic link can force that
link to an remote extent. xfs_inactive() incorrectly assumes
that any symbolic link small enough to be in the inode core
is incore, resulting in the remote extent to not be removed.
xfs_ifree() will assert on presence of this leaked remote extent.

Add a header to the remote symlink block, containing location and
owner information, as well as CRCs and LSN fields. This requires
verifiers to be added to the remote symlink buffers for CRC enabled
filesystems.
This also fixes a bug reading multiple block symlinks, where the second
block overwrites the first block when copying out the link name.

The symlink code is about to get more complicated when CRCs are
added for remote symlink blocks. The symlink management code is
mostly self contained, so move it to it's own files so that all the
new code and the existing symlink code will not be intermingled
with other unrelated code.
