* Simplify EINTR/ECANCEL error handling
1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx
* Unify the void cast usage
1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro
Iobinstrumentation
* mm/iob: Introduces producer/consumer id to every iob call. This is so that the calls can be instrumented to monitor the IOB resources.
* iob instrumentation - Merges producer/consumer enumeration for simpler IOB user.
* fs/procfs: Starts adding support for /proc/iobinfo
* fs/procfs: Finishes first pass of simple IOB user stastics and /proc/iobinfo entry

Mac802154 fixes
* mac802154: Frame Version should have been 1, but was being set to 3 when payload exceeds version 0 capabilities.
* mac802154: Corrects function reference in warning print-out
* mac802154/sixlowpan: Adds warning to build to indicate what is noted in the menu for CONFIG_MAC802154_NTXDESC

mac802154: Fixes issue where the txdesc's ackreq flag was not being set, despite the frame containing a Frame Control field with ACKREQ bit set.

mac802154: Fixes issues with extended address. 1) Extended address should be read-only. 2) Extended address should be placed in frame in "reverse-canonical" order.
The extended address is a read-only attribute and thus an attempt to write the extended address should be denied. Instead, the extended address should really be either set by the PHY/radio itself, or provided at board bring-up time to the radio layer. The MAC layer now pulls in the extended address from the radio any time the MAC is reset.
The extended address is also supposed to be sent in the frame in reverse-canonical order. This is very confusing in the standard and it wasn't until I realized it was backwards in Wireshark that I researched this further. Searching online I find documents from the committee for suggestions/feedback on the future standard. It isn't in the 2015 standard but a newer version of the standard will presumably clarify this. It says that the extended address should be written in reverse-canonical form, meaning the OUI comes last, not first inside the frame.

wireless/ieee8021254: Adds support for energy detect.
Adds support for energy detect by introducing a new radio call/callback, as the PHY layer is required to perform the energy detect.

Fixed coding standard error in several files. Use of while( is incorrect; a space is required between while and (. Also ran tools/nxstyle and fix thoses complaints as well in most files.
Changes to comply with coding standard. Mostly focused on files with missing space after keyword in if(, switch(, and for(. Offending files also got changes to comply with tools nxstyle. If there were logs of nxstyle complaints, the file also got a taste of tools/indent.sh. Still need to fix occurrences of while( with missing space. There are a lot of them.
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

libc/semaphore: Add nxsem_getvalue() which is identical to sem_getvalue() except that it never modifies the errno variable. Changed all references to sem_getvalue in the OS to nxsem_getvalue().
sched/semaphore: Rename all internal private functions from sem_xyz to nxsem_xyz. The sem_ prefix is (will be) reserved only for the application semaphore interfaces.
libc/semaphore: Add nxsem_init() which is identical to sem_init() except that it never modifies the errno variable. Changed all references to sem_init in the OS to nxsem_init().
sched/semaphore: Rename sem_tickwait() to nxsem_tickwait() so that it is clear this is an internal OS function.
sched/semaphoate: Rename sem_reset() to nxsem_reset() so that it is clear this is an internal OS function.
Merged in merlin17/nuttx/mac802154-sock (pull request #479)
wireless/ieee802154: Adds support for receiving MAC events via IOCTL through socket interface. Other small fixes and cleanup
* ioctl: Cleans up MAC802154IOC values
* wireless/ieee802154: Cleans up MAC802154IOC_NOTIFY_REGISTER logic in character driver
* wireless/ieee802154/mac802154_netdev: Adds support for MAC event notification via IOCTL
* wireless/ieee802154/mac802154: Changes reset logic. No longer reset extended address.
* wireless/ieee802154: Cleans up MAC802154IOC logic
Moves MAC802154IOC from ieee802154_ioctl.h and renames ieee802154_ioctl.h to ieee802154_device.h since it only contains types relevant to the MAC char device now.
* wireless/ieee802154/mac802154_device: Cleans up IOCTL logic for recent changes.
* drivers/wireless/ieee802154/mrf24j40: Adds missing break in case statement

* wireless/ieee802154/mac802154: Fixes poll logic meant to automatically choose address mode based on short address range.

Before, the MAC timer used a watchdog to schedule work with the high priority worker queue. However, since everything in the MAC is supposed to be serialized through the use of the high priority work queue, but the timer uses a watchdog, there are some unintended consequences. To simplify, we now use the delayed work feature of the work queue.
