Port STM32F7 I2C driver to STM32L4
* arch/stm32l4: port STM32F7 I2C driver to STM32L4
STM32L4 I2C driver is in work-in-progress state (plentiful of
TODOs and #warnings) and lags many features found in more
up-to-date STM32 I2C drivers. The peripheral on STM32F7 and
STM32L4 are identical except for L4's 'wakeup from stop mode'
flag and STM32F7's I2C driver is in more 'ready to use' state.
Patch ports the STM32F7 I2C driver to STM32L4. The I2C clock
configuration is kept the same as before (I2CCLK = PCLK1 80 Mhz)
instead of switching to STM32F7 arch default that is I2CCLK=HSI.
Further work would be to add configuration option for choosing
I2C clock source instead of current hard-coded default.
* arch/arm/stm32f7: i2c: restore bus frequency after I2C reset
Copy frequency restoration fix from STM32L4 I2C driver to STM32F7 I2C driver.
* arch/arm/stm32f7: i2c: remove unused Kconfig option
* configs/nucleo-l496zg/nsh: enable I2C4 bus with i2ctool

Squashed commit of the following:
net/icmpv6: IPPROT_ICMP6 socket logic now builds without error.
net/icmpv6: Add support for read-ahead and poll(). Initial commit is just cloned from ICMP with the appropriate name changes.
configs/: All defconfig filess that include CONFIG_NET_ICMPv6_SOCKET=y need to select CONFIG_SYSTEM_PING6=y and deselect CONFIG_DISABLE_POLL.
Update NSH documention to show that ping6 is now a built in command.
net/icmpv6: Add icmpv6_sendto.c and icmpv6_recvfrom.c. Initial versions are just clones from icmp/ with appropriate name changes.
net/icmpv6: Clone some ICMP socket logic as the beginning of support for ICMPv6 socket support.
Rename CONFIG_NET_ICMPv6_PING to CONFIG_NET_ICMPv6_SOCKET. Move prototype for icmpv6_ping from include/nuttx/net/icmpv6 to net/icmpv6/icmpv6.h
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.

BCM2708: Add enough infrastructrue (more stubs) to get a clean compilation of the Pi Zero configuration (with many undefined things at link time).
BCM2708: Add basic interrupt handling logic
BCM2708: Add interrupt register definitions.
BCM2708: Add irq.h header file
BCM2708/Pi zero: bcm_boot.c and bcm_memorymap.h now compile. Added pizero linker script.
BCM2708/Pi Zero: Add Make.defs needed to build.
arch/arm/include/bcm2708, arch/arm/src/bcm2708, configs/pizero: Add some basic build and configuration logic.
configs/pizero: Add some basic structure of the Rasperry Pi Zero port.
Created directory configs/pizero. Nothing there now but a README.txt file.
Add initial boot.c and memorymap.c files

BCM2708 memory map: Add VBASE defintions; fix VCSDRAM address per Alan; move all virtual address to the bottom of the file to avoid confusion -- top is all physical address; bottom is all veritural address.
Add initial memory map to BCM2708/BCM2835

sched/mqueue: Rename all private static functions for use the nxmq_ vs. mq_ naming.
sched/mqueue: Rename all OS internal functions declared in sched/mqueue/mqueue.h to begin with nxmq_ vs. mq_. The mq_ prefix is reserved for standard application interfaces.
