tofu: Compare squares instead of square roots.
* g10/Makefile.am (tofu_source) [USE_TOFU]: Remove sqrtu32.h and
sqrtu32.c.
* g10/sqrtu32.h, g10/sqrtu32.c: Removed files.
* g10/tofu.c: Compare squares instead of square roots.
--
The original code is a factor 11.5 slower than using libm's sqrt(),
which in turn is a factor 3.5 slower than using one multiplication
on the other side of the comparison. Also, it's much simpler now.
