Squashed commit of the following:
net/icmp: Finishes off icmp_recvfrom().
net/icmp: Add readahead support for IPPROTO_ICMP sockets.
net/icmp: Add poll() support for IPPROTO_ICMP sockets.
net/icmp: Add a connection structure for IPPROTO_ICMP sockets.
net/icmp: Implements sendto for the IPPROTO_ICMP socket.
net/icmp: Move icmp_sendto() and icmp_recvfrom() to separate files. They are likely to be complex (when they are implemented).
net/icmp: Hook IPPROTO_ICMP sockets into network. Fix some naming collisions. Still missing basic ICMP send/receive logic.
configs: apps/system/ping current need poll() enabled.
configs: All defconfig files that use to enable low-level support must now enabled CONFIG_SYSTEM_PING.
net/icmp: Adds basic build framework to support IPPROTO_ICMP sockets.
Master
* stm32_hrtim: fix warnings related with RCC
* stm32f33xxx_adc: add some publicly visable interfaces and some code to support injected channels
* stm32f33xxx_dma: add public interface to handle with DMA interrupts
* stm32_hrtim: change some names and add some coments
* chip/stm32f33xxx_adc.h: cosmetics
* nucleo-f334r8: add logic for zero latency high priority interrupts example
* stm32: update some ADC-related configuration in Kconfig
Approved-by: Gregory Nutt <gnutt@nuttx.org>
STM32L1, STM32L4 RTC: add periodic interrupts, update L1 RTC implementation
* STM32L4 RTC: add support experimental CONFIG_RTC_PERIODIC
* STM32 RTC: separate STM32L1 RTC into a separate file
STM32L1 RTC is very close to F4 or L4 versions, with two alarms
and periodic wakeup support so backported L4 peripheral to L1.
* RTC: add periodic alarms to upper and lower halves

Master
* stm32f33xxx_adc.c: fix some warnings and compilation error when extsel not in use
* nucleo-f334r8/adc: change serial console to USART2 (STLINK COM)

The same interrupt handler is entered with the device structure parameter in all situations,
multiple or single PCA. One should still be careful if multiple PCA devices share the same IRQ.
Lower part of STM32 CAN driver arch/arm/src/stm32/stm32_can.c uses all three hw tx mailboxes and clears TXFP bit in the CAN_MCR register (it means transmission order is defined by identifier and mailbox number).
This creates situation when order frames are put in upper part of CAN driver (via can_write) and order frames are sent on bus can be different (and I experience this in wild).
Since CAN driver API pretends to be "file like" I expect data to be read from fd the same order it is written. So I consider described behaviour to be a bug.
I propose either to set TXFP bit in the CAN_MCR register (FIFO transmit order) or to use only one mailbox.
Stm32 rtc small patches
* RTC: canceling an alarm marks it as inactive
* STM32L4, STM32F4, STM32F7 RTC: fix reading alarm value that is more than 24h in future
* STM32F0 RTC: fix backup register count in stm32_rtcc.h
All other STM32: SHIFTR_SUBFS_MASK was correct in STM32F0 only
* STM32L1: use correct EXTI line definitions
