Zoltán Vörös 27767aafa2 lib/libm_dbl: Add round.c source code.
This code is imported from musl, to match existing code in libm_dbl.

The file is also added to the build in stm32/Makefile.  It's not needed by
the core code but, similar to c5cc64175b,
allows round() to be used by user C modules or board extensions.

Jim Mussared 580a2656d1 stm32: Use hardware double sqrt on F7/H7 MCUs.
Identical to cd527bb324 but for doubles.
This gives a -2.754% improvement on bm_float.py, and -35% improvement on
calling sqrt in a loop.

Andrew Leech 57a73973ad lib/libm_dbl: Add implementation of copysign() for DEBUG builds.
This provides a double variant of the float copysignf from libm/math.c
which is required for DEBUG=1 builds when MICROPY_FLOAT_IMPL=double

Damien George 0b239d458c lib/libm_dbl/tanh: Make tanh more efficient and handle large numbers.
Prior to this patch tanh(large number) would return nan due to inf/inf.
