Big diff, mostly cosmetic.

Big diff, mostly cosmetic.

The two fixes are:
	- osc_con2dlmcl() now fills in rconn properly.
	- lov_connect() gets the mdc_conn data passed in via the conn param

The cosmetic:
	- add a new field to the export struct exp_rconnh.  Don't use the
	  import field, it is for the LDLM to use later.
	- make the export struct elements exp_foo instead of export_foo.
