Reverted some of the nsc xpath API changes. In the revert, xpath_first() and xpath_vec() retain their old syntax with nsc==NULL.

The reason is to be conservative with the API. However, less used functions, such as xpath_vec_bool(), xpath_vec_ctx() and xpath_vec_flag()  are changed with a new `nsc`parameter, which should be set to NULL in most cases.
