lib/libm: Move Thumb-specific sqrtf function to separate file.
...
This allows it to be used only when the hardware supports VFP
instructions, preventing compile errors.

lib/libm: Format code to pass gcc v6.1.1 warning.
...
gcc 6.1.1 warns when indentation is misleading, and in this case the
formatting of the code really is misleading. So adjust the formatting
to be clear of the meaning of the code.

lib/libm: Add acosh, asinh, atanh, tan; get working with stmhal.
...
acoshf, asinhf, atanhf were added from musl. mathsincos.c was
split up into its original, separate files (from newlibe-nano-2).
tan was added.
All of the important missing float functions are now implemented,
and pyboard now passes tests/float/math_fun.py (finally!).

lib: Add lib and libm, moving current files from stmhal.
...
Top-level lib directory is for standard C libraries that we want to
provide our own versions of (for efficiency and stand-alone reasons).
It currently has libm in it for math functions.
Also add atanf and atan2f, which addresses issue #837 .
