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.
Author: Xiang Xiao <xiaoxiang@xiaomi.com>
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.
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

ieee802154/sixlowpan: Removes unnecessary conversions that were happening due to a misunderstanding of byte ordering with EUI-64

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.

mac802154_netdev: Allow 64-bit prefix to be configurable when auto-configuring the IPv6 address during bring-up.
Previously, the link-local prefix fe80::/64 was used. Also, put the network in the DOWN state at the end of initialization.

* 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.

Replace all calls to sigqueue() in the OS proper with calls to nxsig_queue() to avoid accessing the errno variable.
sched/signal: Add nxsig_queue() which is functionally equivalent to sigqueue() except that it does not modify the errno variable.
This commit backs out most of commit b4747286b1. That change was added because sem_wait() would sometimes cause cancellation points inappropriated. But with these recent changes, nxsem_wait() is used instead and it is not a cancellation point.
In the OS, all calls to sem_wait() changed to nxsem_wait(). nxsem_wait() does not return errors via errno so each place where nxsem_wait() is now called must not examine the errno variable.
In all OS functions (not libraries), change sem_wait() to nxsem_wait(). This will prevent the OS from creating bogus cancellation points and from modifying the per-task errno variable.
sched/semaphore: Add the function nxsem_wait(). This is a new internal OS interface. It is functionally equivalent to sem_wait() except that (1) it is not a cancellation point, and (2) it does not set the per-thread errno value on return.
sched/semaphore: Add nxsem_post() which is identical to sem_post() except that it never modifies the errno variable. Changed all references to sem_post in the OS to nxsem_post().
sched/semaphore: Add nxsem_destroy() which is identical to sem_destroy() except that it never modifies the errno variable. Changed all references to sem_destroy() in the OS to nxsem_destroy().
libc/semaphore and sched/semaphore: Add nxsem_getprotocol() and nxsem_setprotocola which are identical to sem_getprotocol() and set_setprotocol() except that they never modifies the errno variable. Changed all references to sem_setprotocol in the OS to nxsem_setprotocol(). sem_getprotocol() was not used in the OS
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.

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.
