ape: deduplicate math.h
This merges all of /$objtype/include/ape/math.h into
/sys/include/ape/math.h.
All headers were exactly the same except some didn't implement
isnan(x) and isinf(x), or they weren't passing the sign
parameter to isInf(d, sign).

Looks the stuff inside this ifdef are standardized:
http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1256.pdf, section 7.12
https://pubs.opengroup.org/onlinepubs/7908799/xsh/math.h.html
We should probably drop the _RESEARCH_SOURCE ifdef.
