2a2f92f7c2 Make ERR_IS_FATAL() test first fatal error instead of last non-fatal error 
This way, we don't need to update ERR_IS_FATAL() every time new non-fatal error

non-fatal errors and fatal errors.

6aed6e659f Rework DHCP PCB handling: Old code registered one UDP PCB per netif where DHCP was active and there was a special case in udp_input() for this. New implementation uses one PCB for all netifs and removes special case in udp_input(). 
The old approach called udp_bind() on each of the PCBs, which puts them into udp_pcbs list. The PCBs were iterated on all non-DHCP udp_inputs() with no effect.
My cleanup removes the special handling in udp.c, and uses only one DHCP UDP PCB to catch all DHCP messages from all netifs. The dhcp_recv function then checks whether ip_current_input_netif() has DHCP enabled - if not, the message is ignored. The PCB is only created/registered when one or more PCBs have DHCP enabled.

8cb64698aa Allow backlog to be updated 
This commit adds support to the sockets and netconn layer to update the
backlog by calling listen when the netconn is already in the listen state.
When backlog is not enabled, the call returns successfully

This commit also introduces a macro for setting the backlog value that
prevents a 0 sized (invalid) backlog

ea94549cb2 Optimize lwip_selscan() 
This makes a couple of simple re-arrangements in lwip_selscan() that
should improve performance in the following ways:

  1) The old code linearly walked all sockets to maxfd regardless of
     whether they were set in the fd set. The process involved
     acquiring sys arch protect, looking up the socket, and then
     checking if the socket was present in any of the fd sets. On
     systems with lots of sockets and a heavy SYS_ARCH_PROTECT
     infrastructure (a mutex) this can result in a lot of extra work.
     Now we skip this process for any fd that is not in the input sets
  2) If the socket from tryget_socket() is NULL we no longer continue
     and compare the input fd sets with a zeroed out set of events
  3) We no longer need to zero out our event sets because they are
     only accessed when tryget_socket() is successful

lwip_selscan() is called at most once per select call and sometimes up to three times

sign_extension: Suspicious implicit sign extension: count with type unsigned short (16 bits, unsigned) is promoted in count * size to type int (32 bits, signed), then sign-extended to type unsigned long (64 bits, unsigned). If count * size is greater than 0x7FFFFFFF, the upper bits of the result will all be 1.
