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

ac4b089b18 udp.c: Further udp_input simplifications
- Move local PCB matching code in a function that can be reused in SO_REUSE && SO_REUSE_RXTOALL case.
- Some checks have been written in the dual-stack version and then repeated with the ipv6-only version. Example:
IPv6 only: ip6_addr_ismulticast(ip6_current_dest_addr())
IPv4 AND IPv6: ip_addr_ismulticast(ip_current_dest_addr())

880f1008d6 Together with Simon: Eliminate last instances of isipv6 member in pcbs;
Don't allow NULL pointers (IPv4 ANY) in connect() and sendto() functions as destinations since this does not make sense.

273d609bac mem.c: Fix unintended sign extension (found by Coverity)
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.
