8b2c73de4e ip4: routing: check peer for point to point interfaces 
gw netif field for point to point interfaces is the peer IP address.
Check if the destination is equals to the gw field of point to point
interfaces (broadcast flag is not set) when routing an IP packet.

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

ce7e31cd04 task #12722 (improve IPv4/v6 address handling): renamed ip_addr_t to ip4_addr_t, renamed ipX_addr_t to ip_addr_t and added IP version; 
ip_addr_t is used for all generic IP addresses for the API, ip(4/6)_addr_t are only used internally or when initializing netifs or when calling version-related functions

9f065c0ea5 (api break) qualify ip_addr_t as const where feasible 
this changes the callback signatures of the ip_output and the
{udp,raw}_recv functions.

changes were made by going through all header files, searching for
occurrences of ip_addr_t, qualifying them as const and if required
modifying the corresponding c files, looking for other uses of ip_addr_t
that would be required.

the following header files were not treated as i'm not using them and
wouldn't see them compiled: api.h api_msg.h dhcp.h dns.h igmp.h
netifapi.h pppapi.h snmp.h snmp_msg.h snmp_structs.h ppp.h pppol2tp.h
test/*

no modifications were done on ip6_addr_t.
