Subject: lib/vsprintf: declare no_hash_pointers in sprintf.h
Date: Mon, 14 Aug 2023 19:33:44 +0300

Sparse is not happy to see non-static variable without declaration:
lib/vsprintf.c:61:6: warning: symbol 'no_hash_pointers' was not declared. 
Should it be static?

Declare respective variable in the sprintf.h.  With this, add a comment to
discourage its use if no real need.
