Re: vasnprintf, u*-vasnprintf: Support string arguments longer than 2 GiB

[Bruno Haible]

Three more patches in this series:

1) Fix a small mistake that caused gcc warnings.
2) I measured the amount of RAM that the tests need:
     $ /usr/bin/time -f "Max RSS: %M KiB" ./test-...printf-big
   This is consistent with what I see by watching the process through "top".
3) vasnwprintf tests: Add test of %s directive with large arguments.
   This test passes without modifications to lib/vasnprintf.c. The
   corresponding code is in lines 3141..3628.

        vasnprintf, u*-asnprintf tests: Adjust memory need.
        * tests/test-vasnprintf-big.c (main): Require 10, not 12, GiB of RAM.
        * tests/unistdio/test-u8-asnprintf-big.c (main): Require 15 GiB of RAM.
