lib: Update stm32f1 code to version 1.8.0

Update the stm32f1 code to the latest from ST.  Merge the
lib/cmsis-stm32f1/ and lib/hal-stm32f1/ into a single lib/stm32f1/
directory.  Document all the differences from the pristine upstream
code.

-  * @file    stm32f1xx_hal_timebase_rtc_alarm_template.c 

-  * @author  MCD Application Team

-  * @version V1.1.1

-  * @date    12-May-2017

-  * @brief   HAL time base based on the hardware RTC_ALARM.

-  *

-  *          This file override the native HAL time base functions (defined as weak)

-  *          to use the RTC ALARM for time base generation:

-  *           + Intializes the RTC peripheral to increment the seconds registers each 1ms

-  *           + The alarm is configured to assert an interrupt when the RTC reaches 1ms 

-  *           + HAL_IncTick is called at each Alarm event and the time is reset to 00:00:00

-  *           + HSE (default), LSE or LSI can be selected as RTC clock source

-  ==============================================================================

-    [..]

-    This file must be copied to the application folder and modified as follows:

-    (#) Rename it to 'stm32f1xx_hal_timebase_rtc_alarm.c'

-    (#) Add this file and the RTC HAL drivers to your project and uncomment

-       HAL_RTC_MODULE_ENABLED define in stm32f1xx_hal_conf.h 

-

-    [..]

-    (@) HAL RTC alarm and HAL RTC wakeup drivers can’t be used with low power modes:

-        The wake up capability of the RTC may be intrusive in case of prior low power mode

-        configuration requiring different wake up sources.

-        Application/Example behavior is no more guaranteed 

-    (@) The stm32f1xx_hal_timebase_tim use is recommended for the Applications/Examples

-          requiring low power modes
