There were 2 bugs, now fixed by this patch:
- after deleting an element the len of the dict did not decrease by 1
- after deleting an element searching through the dict could lead to
a seg fault due to there being an MP_OBJ_SENTINEL in the ordered array
The patch enables the possibility to disable or initialize the repl
info from outside of the module. Can also be used to initialize the
repl_display_debugging_info in pyexec.c if not startup file is clearing
.bss segment.
The renames are:
HAL_Delay -> mp_hal_delay_ms
sys_tick_udelay -> mp_hal_delay_us
sys_tick_get_microseconds -> mp_hal_ticks_us
And mp_hal_ticks_ms is added to provide the full set of timing functions.
Also, a separate HAL_Delay function is added which differs slightly from
mp_hal_delay_ms and is intended for use only by the ST HAL functions.
The sdk_12.1.0 nrf52_ble.c implementation was dependent on SDK components.
This has been replaced with the ble_uart.c implementation using a standalone
bluetooth driver implementation without need of SDK components.
Also, sdk.mk has been updated to not use a special linker script.
Script does not really work very well with blocking char read and
async ble notifications printing data when terminal stdout is blocked
by readchar. Bluetooth UART profile implemented in ble_uart.c is
now working with tralamazza's nus_console nodejs script.

Disable Bluetooth UART to be used for REPL by default. Can be overridden
in nrf5_sdk_conf.h. It is defined in mpconfigport.h as it is connected to
mphalport.c, where the config is used to determine whether default print
functions should be using HW UART or Bluetooth UART.
ble_uart.c implements UART Bluetooth service on top of the
bluetooth stack driver api calls. Can be enabled to be compiled
in by defining MICROPY_PY_BLE_NUS = 1 in nrf5_sdk_conf.h.
If BLE UART service has been enabled, the mp_hal_stdout_tx_strn_cooked
is not defined by default anymore, and has to be implemented by the
UART driver (in this case BLE).
User can override PYTHON executable before running script,
gen-cpydiff.py works only with Python3 and most systems register
its executable as 'python3'.
I also didn't see any real reason for mkrules.mk to exist,
so I merged the contents into Makefile.
Now you can do:
```
make BOARD=pca10028 clean
make BOARD=pca10028 flash
```
and it will work properly.
