2e26fc9224 tcp: Avoid 3-second delay for a half-open connection 
If lwIP encounters a half-open connection (e.g. due to a restarted
application reusing the same port numbers) it will correctly send a
RST but will not resend the SYN until one retransmission timeout later
(approximately three seconds).  This can increase the time taken by
lpxelinux.0 to fetch its configuration file from a few milliseconds to
around 30 seconds.

Fix by immediately retransmitting the SYN whenever a half-open
connection is detected.

lwip/src/core/init.c:256:32: error: "LWIP_COMPAT_MUTEX" is not defined [-Werror=undef]

Setting LWIP_TCPIP_CORE_LOCKING is meaningless for NO_SYS targets,
therefore checking if LWIP_COMPAT_MUTEX is set does not make sense.

to prevent priority inversion on tcpip_thread operations)

cfe5182380 timers: fix wrong timings for !NO_SYS targets 
issue 1:

sys_arch_sem_wait() is supposed to return an elapsed time in ms, what could
happen given a > 1 kHz calling rate for high throughput systems is that it
might always returns 0 ms. This is a problem for systems which compute the
elapsed time from a high precision clock source.

This is what is currently happening in the unix port in sys_arch_sem_wait():

start time -> 1000000000;  // ns
-- less than a ms before an event arrive --
end time   -> 1000xxxxxx;  // ns
return value -> (end time - start time)/1000000 -> 0

The return value is used to reduce the next timer interval, if
sys_arch_sem_wait() always return 0 no more timers are fired anymore

issue 2:

The current timer implementation for !NO_SYS targets only count elapsed
time while -waiting- for semaphore and doesn't count at all the time
spent by the stack to process packets. For CPU bound traffic patterns no
more timers are fired anymore.

Both are serious design issues which cannot be easily fixed without reworking
everything. This patch uses the properly implemented timers for NO_SYS targets
for !NO_SYS targets and merge them both into one single timers implementation.

15fbfb7363 PPP, remove useless ppp_init function 
Simon says:

ppp_init() does not seem to be used. The only thing it does is calling
magic_init(), which is not required because it its called again later
from ppp_input().

Also, the time from startup is rather constant, so calling sys_jiffies()
from ppp_init() does not create a random number.

Sockets bound to a multicast address could not transmit multicast

even if the outgoing netif was resolved correctly.

To correct the issue, pcbs with a multicast local address will use
