If SMP is enabled this function will return the number of the CPU that the thread is running on. This is non-standard but follows GLIBC if __GNU_SOURCE is enabled. The returned CPU number is, however, worthless since it returns the CPU number of the CPU that was executing the task when the function was called. The application can never know the true CPU number of the CPU tht it is running on since that value is volatile and change change at any time.
1. Remove the unused and unimplemented ipv6_chksum declaration
2. Update NET_ARCH_CHKSUM description to align with the implementation
3. Declare all checksum function prototype regardless CONFIG_NET_ARCH_CHKSUM
4. Remove the CONFIG_NET_ARCH_CHKSUM guard for tcp_ipv[4|6]_chksum

* Fix CAN driver to work with internal OS interfaces. Store internal file pointer in f_priv and use it then to distinct readers (See issue #111)
* Store reader pointer in f_priv instead of filep
* Don't need in filep in can_reader_s
1.Consolidate absolute to relative timeout conversion into one place(_net_timedwait)
2.Drive the wait timeout logic by net_timedwait instead of devif_timer
This patch help us remove devif_timer(period tick) to save the power in the future.

* 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

Net cleanup (#17)
* Fix the semaphore usage issue found in tcp/udp
1. The count semaphore need disable priority inheritance
2. Loop again if net_lockedwait return -EINTR
3. Call nxsem_trywait to avoid the race condition
4. Call nxsem_post instead of sem_post
* Put the work notifier into free list to avoid the heap fragment in the long run. Since the allocation strategy is encapsulated internally, we can even refine the implementation later.
* Network stack shouldn't allocate memory in the poll implementation to avoid the heap fragment in the long run, other modification include:
1. Select MM_IOB automatically since ICMP[v6] socket can't work without the read ahead buffer
2. Remove the net lock since xxx_callback_free already do the same thing
3. TCP/UDP poll should work even the read ahead buffer isn't enabled at all
* Add NET_ prefix for UDP_NOTIFIER and TCP_NOTIFIER option to align with other UDP/TCP option convention
* Remove the unused _SF_[IDLE|ACCEPT|SEND|RECV|MASK] flags since there are code to set/clear these flags, but nobody check them.

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.

drivers/mtd/w25qxxxjv.c: Add QSPI-based Winbond NOR FLASH driver
drivers/mtd/Kconfig: include w25qxxxjv mtd driver to menuconfig
mtd/mtd.h: add function prototype of w25qxxxjv_initialize
We also make an attempt to avoid the thundering herd problem if there are multiple readers/pollers.
Patch also removes forcing CONFIG_RAMLOG_CRLF in nuttx/syslog/ramlog.h as there is no point of wasting precious RAM for useless characters.
This change decouples that upper activity-based logic from the lower random walk logic and allows use of other upper state detection logic (such as a custom, application-specific state machine).
net/netlink/netlink_route.c: Add Netlink socket NETLINK_ROUTE support for getting a snopshot of the Neighbor table.
net/neighbor/neighbor_snapshot.c: Add neighbor_snapshot() that will eventually be used by the Netlink sockets. Also fixed naming violation 'struct neighbor_entry' -> 'struct neighbor_entry_s'.
include/nuttx/net/neighbor.h: Expose format of the IPv6 neighbor table for use with Netlink sockets.

According to earlier standards, usage of select(), FD_CLR, FD_ISSET, FD_SET and FD_ZERO
just need include headers: sys/time.h, sys/types.h and unistd.h. So include sys/select.h
in time.h to compatible with it. Or mbedtls library would build break in calling select()
and FD_* related functions.

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);

task_spawn() and posix_spawn() are NuttX OS interfaces. In PROTECTED and KERNEL build modes, then can be reached from applications only via a system call. Currently, the number of parameters in a system call is limited to six; these spawn function have seven parameters. Rather than extend the maximum number of parameters across all architectures, I opted instead to marshal the seven parameters into a structure.
*
In order to support builtin in function in protected mode, a task_spawn() system call must be supported. Unfortunately this is overly complex because there is a (soft) limit of 6 parameters in a system call; task_spawn has seven paramters. This is a soft limit but still difficult to extend because it involves assembly language changes to numerous architectures. Better to get more creative.
Squashed commit of the following:
Correct some additional compile-related issues.
Move include/nuttx/binfmt/builtin.h to include/nuttx/lib/builtin.h. Move apps/builtin/lib_builtin_forindex.c to libs/libc/builtin/lib_builtin_forindex.c.
Move binfmt/libbuiltin to libs/libc/builtin. There are calls made directly from apps/nshlib into this logic and hence, must be part of a library that can be shared between the OS and applications.
