Merge branch 'teensy-new' of github.com:dhylands/micropython into dhylands-teensy-new Conflicts: stmhal/pin_named_pins.c stmhal/readline.c Renamed HAL_H to MICROPY_HAL_H. Made stmhal/mphal.h which intends to define the generic Micro Python HAL, which in stmhal sits above the ST HAL.

// We use the ST Cube HAL library for most hardware peripherals
#include <stm32f4xx_hal.h>
// Basic GPIO functions
#define GPIO_read_pin(gpio, pin) (((gpio)->IDR >> (pin)) & 1)
#define GPIO_set_pin(gpio, pin_mask) (((gpio)->BSRRL) = (pin_mask))
#define GPIO_clear_pin(gpio, pin_mask) (((gpio)->BSRRH) = (pin_mask))
Add support for selecting pin alternate functions from python. Converts generted pins to use qstrs instead of string pointers. This patch also adds the following functions: pyb.Pin.names() pyb.Pin.af_list() pyb.Pin.gpio() dir(pyb.Pin.board) and dir(pyb.Pin.cpu) also produce useful results. pyb.Pin now takes kw args. pyb.Pin.__str__ now prints more useful information about the pin configuration. I found the following functions in my boot.py to be useful: ```python def pins(): for pin_name in dir(pyb.Pin.board): pin = pyb.Pin(pin_name) print(&#39;{:10s} {:s}&#39;.format(pin_name, str(pin))) def af(): for pin_name in dir(pyb.Pin.board): pin = pyb.Pin(pin_name) print(&#39;{:10s} {:s}&#39;.format(pin_name, str(pin.af_list()))) ```

stmhal: Use OSError with POSIX error code for HAL errors. Addresses issue #921.

extern const byte mp_hal_status_to_errno_table[4];
NORETURN void mp_hal_raise(HAL_StatusTypeDef status);
stmhal: Reduce coupling between USB driver and readline. This makes it easier to re-use readline.c and pyexec.c from stmhal in other ports.
