Move functionality of net_conf_showshare() to libnet_conf.c

The functionality is moved to a new function libnet_smbconf_getshare().
This returns the parameters of the given share as two lists: the list
of parameter names and the list of matching (formatted) parameter values.

The retrieval and formatting is done in a new internal helper function
libnet_smbconf_reg_get_values() that is to become the replacement for
list_values() from net_conf.c once functionality of net_conf_list() has
been moved to libnet_conf, too.
