Summary:
- In arp_send(), arp_wait_setup() adds a notify object to g_arp_waiters
which is removed in arp_wait() in normal case.
- However, in timeout and error cases, the object was not removed and
caused memory corruption.
- This commit fixes this issue.
Impact:
- None
Testing:
- Tested with spresense:rndis_smp

Summary:
- In arp_wait_setup() and arp_wait_cancel(), g_arp_waiters
is protected by a critical section.
- However, I noticed that arp_notify() does not protect the
g_arp_waiters that would cause memory corruption
- This commit fixes the issue.
Impact:
- None
Testing:
- Tested with spresense:rndis_smp, spresense:rndis

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/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.
Normally it is required that the network be in the "down" state when re-configuring the network interface. This is thought not to be a necessary here because.
1. The ICMPv6 logic here runs with the network locked so there can be no outgoing packets with bad source IP addresses from any asynchronous network activity using the device being reconfigured.
2. Incoming packets depend only upon the MAC filtering. Network drivers do not use the IP address; they filter incoming packets using only the MAC address which is not being changed here.
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
