Import Sprout. This is to fix the build on clang.

Browse source 
Sprout is needed because pow, log2 and log10 are constexpr on gcc,
but that's nonstandard. Sprout provides the constexpr version of
those functions.

Also fix warnings. I still get plenty of warnings about some suggested
paretheses, but it seems to be a bug from clang. See
https://llvm.org/bugs/show_bug.cgi?id=21629 for the bug report.
