RNDIS support on STM32F4Discovery
* stm32f4discovery: Add stm32_netinit.c to avoid a compilation error
* stm32f4discovery: Add rndis initialization in stm32_bringup.c
NOTE: MAC address for the host side starts 0xaa. This assignment
scheme should be fixed later.
* stm32f4discovery: Add rndis configuration
NOTE: STM32F4Discovery + DM-STF4BB
* drivers/usbdev/rndis.c: Fix some issues in rndis.c
Introduce rndis_transmit() and change rndis_rxdispatch() to avoid
packet corruption. Introduce max packet size for dual speed which
is mainly used for high speed mode. Fix adjusting MTU warning
on Linux host. Fix data corruption if a packet size excceds MTU.
NOTE: Max packet size is not configured dynamically. This should
be fixed in the future version.
* stm32f4discovery: Modify #ifdef condition for rndis in stm32_bringup()
* drivers/usbdev/rndis.c: Change HPWORK to ETHWORK
* drivers/usbdev/rndis.c: Merge the commit 07b98ccbb5
Previous commit b09365784a was based on old rndis.c thus resulted
in reverting the commit 07b98ccbb5. This change merges the commit.
NOTE: In the commit 07b98ccbb5, max packet size of bulkout was
assumed to be 64. In this commit, priv->epbulkout->maxpacket is
used instead.

This conversion is unfortunate in the sense that Unix local domain sockets are relatively lightweight. LocalHost UDP sockets are much heavier weight since they rely on the full UDP stack. If anyone is up for a complete redesign, then using some shared memory and a POSIX message queue would be lightweight again.
This commit also fixes several bugs that were not testable before the inode tree deadlock. I cannot say that the logic is 100% stable but it does not have basic functionality.
Squashed commit of the following:
fs/userfs: Order locking so that access to the shared I/O buffer is also locked.
fs/userfs: Converts to use LocalHost UDP loopback for IPC.
According to the specification, the close function must wait until all data
has been written before it closes the file (except O_NONBLOCK is set). The
maximum waiting time for this is not specified.
To be able to edit the file list of the process, the close function has to lock
the file list semaphore. After that the close function of the serial driver is
called.
Waiting for the complete transmission of all data is done in the serial driver.
This causes the semaphore to remain locked until all data has been sent.
However, no other thread of the process can edit the file list for that time
(open, close, dup2, etc.). This is not optimal in a multithreaded environment.
Therefore, we have to keep the waiting time within the driver as short as possible.
ieee802154: Simplifies notify() and rxframe() calls to a single notify() call. dataind's and all other "notifs" are now "primitives" which aligns with standard terminology
* mac802154: Adds missing breaks from case statement
* sixlowpan: Fixes bad logic where ACK is not requested if address is not a broadcast
* ieee802154: Simplification of "notifs" and "datainds" to generic primitives passed via a single notify call to the layer above the MAC
* Directories.mk should reference CONFIG_WIRELESS instead of CONFIG_DRIVERS_WIRELESS
* xbee_netdev: Network must be locked when calling sixlowpan_input
* sixlowpan: Reassembly buffer can't be freed if provided by radio driver
* sixlowpan: Don't free IOB if there is an error processing it as the MAC will try to pass it along to another receiver
* ieee802154: Adds basic logging to ieee802154_primitive.c
* Minor fixes after rebase
* xbee: Adds AT query timeout to retry if XBee doesn't respond to request
* same70-xplained: Adds Xbee support. Makes mikroBus slot Kconfig 'choice'
* mac802154: Removes unused function declaration
* drivers/mrf24j40: Fixes compilation error using . operator rather than -> operator
* mac802154_device: Changes a few mac802154_primtive_free's to ieee802154_primitive_free() and changes notif to primitive in a couple places.
* mac802154: Adds promiscous mode logic to bypass parsing of incoming frames. MAC char device also checks for promiscous mode and passes whole frames including header and FCS to the application if promiscous mode is enabled.
* sixlowpan: Fixes logic to correctly check if packet is large enough to include header. This would cause packets to be considered too small when they are sufficiently sized.
* sixlowpan: Fixes forwarding logic to use forwarding device rather than received device to look up destination link layer address
* net/ipforward: Fixes typo that caused build error when IP forwarding was enabled with CONFIG_NET_ICMPv6_NEIGHBOR enabled as well.
* configs/same70-xplained: Simple spelling fix

Fix GPIO operation of STMPE811 driver.
Fixed issues:
1. STMPE811_GPIO_DIR was defined for register name
and later was redefined to be the pin direction mask
for `stmpe811_gpioconfig`
I decided to change register name to be STMPE811_GPIO_DIR_REG,
and keep pin direction mask STMPE811_GPIO_DIR, so that any
external code that already use this driver will be unchanged.
2. The STMPE811 register GPIO_DIR uses bit value 1 for output
and 0 for input, but `stmpe811_gpioconfig` set the opposite.
3. The call to `stmpe811_gpiowrite` from inside of `stmpe811_gpioconfig`
leaded to deadlock.

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
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
