[lwip-devel] [task #14420] Remove sys_sem_signal from inside SYS_ARCH_PROTECT crit section

[Joel Cunningham]

Follow-up Comment #13, task #14420 (project lwip):

With item 3 I was trying to describe the following execution flow in
event_callback (for !LWIP_TCPIP_CORE_LOCKING case):

1) SYS_ARCH_PROTECT
2) Update sock events, i.e. sock->rcvevent++
3) Save sock events to local, i.e. has_recvevent = sock->rcvevent > 0;
4) Loop over select_cb_list, process scb
5) SYS_ARCH_UNPROTECT/SYS_ARCH_PROTECT
6) Possibly restart if select_cb_ctr changed
7) Goto 4 until scb == NULL

With the refactor, there is now an UNPROTECT/PROTECT between saving the events
(#3) and starting the first iteration of the loop (#4)
