469541984d Improve cstdfloat iostream code. 
Copies input stream parsing from multiprecision.
Fixes https://github.com/boostorg/math/issues/1064
This is still not "proper" iostream code, but it's much better than it was.

de9a1a0ee5 Fix race conditions in differential evolution (#1063) 
Through a combination of silly mistakes, I missed a pile of race conditions in the OpenMP threading.

Switch to C++ threading. Note that this change requires serial generation of trial vectors.

Hopefully I can figure out to parallelize the generation of trial vectors to reduce the serial section a la Ahmdahl's law,
while simultaneously keeping thread sanitizer happy.

0e3b29f389 ten should be a constexpr as a float 
Its int counterpart is a constexpr, and the ten variable never changes, so for consistency, we should make float_type ten constexpr as welll.

eaf876c81e Correct non-central-t series convergence bug. 
Fixes https://github.com/boostorg/math/issues/1035.
See also https://github.com/scipy/scipy/issues/19348.
Accuracy in left tail is still poor, and the reflection formula appears to be to blame as it's use causes the series to cancel out the first term, but it appears we have no real choice in the matter here.  At least we do now get a few digits correct.
