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: Allow math funcs to be used by non-Thumb archs.
...
Requires addition of software implementation of sqrtf function.

lib/libm: Add frexp and modf functions; use in stmhal; add tests.
...
Addresses issue #1081 .

stmhal: Add fake implementation of __aeabi_f2lz().
...
To make mp_obj_new_int_from_float() somehow work.

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!).

py: Implement divmod, % and proper // for floating point.
...
Tested and working on unix and pyboard.

py and libm: Add asinf,acosf; print higher precision for float.
...
Also use less stack space when printing single precision float.
Addition of asinf and acosf addresses issue #851 .

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 .
