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.

@ -480,7 +480,7 @@ You use XPATHs on the XML trees in the transaction commit callback.
Suppose you want to print all added interfaces:
```
cxobj *target = transaction_target(td); # wanted XML tree
vec = xpath_vec_flag(target, "//interface", &len, XML_FLAG_ADD); /* Get added i/fs */
vec = xpath_vec_flag(target, NULL, "//interface", &len, XML_FLAG_ADD); /* Get added i/fs */
for (i=0; i<len; i++) /* Loop over added i/fs */
clicon_xml2file(stdout, vec[i], 0, 1); /* Print the added interface */
```
