libedit : feel like obsoleting el_data_get/set

Hello;

In my attempt to update libedit and make it somewhat more in line with
NetBSD's code I found we added two private functions: el_data_get and
el_data_set:

http://svnweb.freebsd.org/base?view=revision&revision=50070 


According to OpenGrok we are not using those functions at all, plus
we have had for a while the upstream sanctioned el_get() and
el_set(),
.
I have no hurry to remove them but I do think it would be good to
reduce some differences with NetBSD's version so I have this
patch that I would like to commit as soon as next week.

Raise your hand if you happen to use them and would prefer
the change postponed or not done.

best regards,

Pedro.
