1. No .c file should include a "Public Types" section. Only a header file can define a public type. A .c file can only define a private type. Several files contained private type definitions. The section that they were defined in, however, was incorrectly named "Public Types." Those were easilty changed to "Private Types" which is what they are.
2. No .c file should include a "Public Function Prototypes" section. All global function prototypes should be provided via a header file and never declared with a .c file.
For No. 2, I corrected as many cases as was reasonable for the time that I had available. But there are still a dozen or so .c files that declare "Public Function Prototypes" within a .c file. This is bad programming style. These declarations should all be moved to the proper header files.
* 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

Ran nxstyle against many of the affected files. But this job was too big for today. Many of the network drivers under arch are highly non-compiant and generate many, many faults from nxstyle. Those will have to be visited again another day.

This effects all network drivers as well as timing related portions of net/: devif_poll_tcp_timer shouldn't be skipped in the multiple card case. devif_timer will be called multiple time in one period if the multiple card exist, the elapsed time calculated for the first callback is right, but the flowing callback in the same period is wrong(very short) because the global variable g_polltimer is used in the calculation. So let's pass the delay time to devif_timer and remove g_polltimer.
Most of the bluetooth and wifi chips appear to need external firmware, and the 43438 is no exception. Fortunately, since Cypress got involved, these are much more straightforward to obtain and are shipped as part of their SDK, which is downloadable from their website. Those firmwares are already provided as C arrays, so their names just need updating to;
const unsigned char bt_firmware_hcd -> The bt firmware array.
const int bt_firmware_len = sizeof(bt_firmware_hcd);
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 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 network devices: Attach radio to d_buf before registering device to handle forwarding case.
When CONFIG_NET_IPFORWARD is enabled, and CONFIG_NET_6LOWPAN is being used, a packet that attempts to get forwarded on the 6LoWPAN interface will require that the radio's buffer be attached to d_buf. Otherwise the below exception will be hit.
~line 542 of sixlowpan_framelist.c
```
/* Recover the reassembly buffer from the driver d_buf. */
reass = (FAR struct sixlowpan_reassbuf_s *)radio->r_dev.d_buf;
DEBUGASSERT(reass != NULL);
```
The underlying "radio" in this case is the mac802154_netdev.
This behavior has probably not been observed because the buffer is normally attached in the periodic txpoll worker. However, in my case, the 6LoWPAN interace was not UP yet, and therefore the worker hadn't run yet.

ieee802154: Support dynamic FCS length. Adds IEEE802154_ATTR_PHY_FCSLEN.
This change introduces IEEE802154_ATTR_PHY_FCSLEN which the radio layer can support to set/get the FCS length that's added to the end of the frame. One use case, in promiscuous mode, is to add back in the FCS of the received frame by increasing the iob->io_len by the FCS length.

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.

* sixlowpan: Fixes logic surrounding the Universal/Local bit. This bit represents whether the IID is locally/globally administered. The U/L bit is bit 1 of the MSB of the EUI-64. It should only be inverted in cases where there is a full EUI-64. In cases where the IID is derived from say, a short address, this bit should be forced to 0, indicating that it is locally administered.
