H A Dlibzfs_dataset.cdiff 271764 Thu Sep 18 12:20:02 MDT 2014 will zfs_setprop_error(): Handle errno value E2BIG.

This errno value is emitted by dsl_props_set_check() in
sys/cddl/contrib/opensolaris/uts/common/fs/zfs/dsl_prop.c, and
is used to mean that the property value is too long. For the record,
the maximum length is ZAP_MAXVALUELEN, which is 8*1024 bytes.

Instead of claiming an unknown error (and abort()ing), provide
something more specific to the scenario involved. As far as I
can tell, E2BIG is not emitted for any other scenario.

Affects: All ZFS versions starting 27 Feb 2009 (illumos ccba0801)
This change modified the value returned by
dsl_props_set_check(), so that it can distinguish between
a name that's too long and a value that's too long, but
libzfs was not updated accordingly.
