156ad0dbf5 udp_bind: Fix the logic to check both pcbs have REUSEADDR set 
The code for #if SO_REUSE case does not match the comment.
By default, we don't allow to bind to a port that any other udp
PCB is already bound to, unless *all* PCBs with that port have tha
REUSEADDR flag set.

Which means we want to omit checking for the same port if both pcbs
have REUSEADDR set. Fix the logic accordingly.

5056d375f2 tcp_bind/tcp_connect: Omit checking for the same port if no port specified 
No port specified means to use a random port.
tcp_new_port() returns a new (free) local TCP port number on success.
So in this case we don't need iterating all lists to test if the port
number is used, tcp_new_port() alreay ensures the port is not used.

708beb4874 udp_bind: Allocate a random port earlier to correctly detect port conflict 
Current code does not correctly detect port conflict if no port specified
because it checks ipcb->local_port == port before udp_new_port().
Fix it by allocating a random port earlier.

72b3f3f612 Hook up TCP cachehit stat 
This commit hooks up the TCP cachehit stat to the PCB locality feature
so that when a PCB is moved to the head of the list and a segment comes
in, we consider this a cache hit

This also matches the usage of the cachehit stat in UDP

177c06b1f1 - prework for fixing bug #45029: access IPv4 configuration of struct netif via new API (netif_ip4_addr()/netif_ip4_netmask()/netif_ip4_gw()) instead of accessing the struct member directly. This way, we can change the struct member types from ip4_addr_t to ip_addr_t; 
- fixed some bugs in calls to ip4_addr*() where the cast to u8_t* did not reveal the wrong address type
