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.

* Fix #692
Add license header to (almost) all files.2014-05-03T22:27:38+00:00Damien Georgedamien.p.george@gmail.com2014-05-03T22:27:38+00:00urn:sha1:04b9147e150d2d6fa3750f312fe328b6a71c1b28
Blanket wide to all .c and .h files. Some files originating from ST are
difficult to deal with (license wise) so it was left out of those.
Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.
stmhal: Update ADC, DAC and I2C objects to use new buffer protocol.2014-04-18T22:28:56+00:00Damien Georgedamien.p.george@gmail.com2014-04-18T22:28:56+00:00urn:sha1:38ae014e4258811d1612f9e140a35f8f9aa0ddb8
Main reason for expanding buffer protocol API was to support writes to a
buffer in ADC module (see read_timed). With this change you can now
create an array of arbitrary type and ADC.read_timed will store into
that array in the correct format (byte, int, float). I wonder though if
all these changes were really worth it to support just this function.
Hopefully this enhanced buffer protocol API (with typecode specified)
will be used elsewhere.
stmhal: Add more math functions.2014-04-16T23:13:13+00:00Damien Georgedamien.p.george@gmail.com2014-04-16T23:13:13+00:00urn:sha1:89831d02896372730899d37edc4054fb3424c21b
Taken straight from musl and newlib. License seems compatible with MIT.
