20beff9ae3 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.

bcf041f1a3 stmhal: Add wiznet5k module, to control WIZnet ethernet adaptor. 
Allows to create socket objects that support TCP and UDP in server and
client mode.  Interface is very close to standard Python socket class,
except bind and accept do not work the same (due to hardware not
supporting them in the usual way).

Not compiled by default.  To compile this module, use:
make MICROPY_PY_WIZNET5K=1

ecc88e949c Change some parts of the core API to use mp_uint_t instead of uint/int. 
Addressing issue #50, still some way to go yet.

8707ea3421 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.

34e43c7ee9 stmhal: Improve efficiency of SysTick IRQ and HAL_Delay. 
SysTick IRQ now increases millisecond counter directly (ie without
calling HAL_IncTick).  Provide our own version of HAL_Delay that does a
wfi while waiting.  This more than halves power consumption when running
a loop containing a pyb.delay call.  It used to be like this, but new
version of HAL library regressed this feature.

29c92a407c stmhal: Use MP_OBJ_NEW_SMALL_INT directly in pyb.micros/millis. 
Also some whitespace cleanup.

2bf044442e Add support for pyb.micros() by using the systick timer. 
I also removed trailing spaces from modpyb.c which affected a couple
of lines technically not part of this patch.

Tested using: https://github.com/dhylands/upy-examples/blob/master/micros_test.py

which eventually fails due to wraparound issues (I could fix the test to compensate
but didn't bother)

e5cbb70328 stmhal: Make enable_irq and disable_irq inline functions. 
These functions are generally 1 machine instruction, and are used in
critical code, so makes sense to have them inline.

Also leave these functions uninverted (ie 0 means enable, 1 means
disable) and provide macro constants if you really need to distinguish
the states.  This makes for smaller code as well (combined with
inlining).

Applied to teensy port as well.

3c658a4e75 py: Fix bug where GC collected native/viper/asm function data. 
Because (for Thumb) a function pointer has the LSB set, pointers to
dynamic functions in RAM (eg native, viper or asm functions) were not
being traced by the GC.  This patch is a comprehensive fix for this.

Addresses issue #820.

that goes after the internal flash drive.

b63be37be1 stmhal: In safe mode, still mount SD card and present as MSD over USB. 
It's still "safe" because no scripts are run.  Remove the SD card if you
want to access the internal flash filesystem.  Addresses issue #616.

Also: remove obsolete pyb.source_dir setting, and reset pyb.main and
pyb.usb_mode settings on soft-reset.

tests pass.
