changed uip_buf to a union for 32-bit alignment

The recent change turning uip_buf from an array to a pointer seems a quite heavyweight way to have the uip_buf alligned to a 32-bit boundary. Contiki is - still - supposed to be portable across a wide range of toolchains - therefore it i.e. intentionally doesn't use C99 features. From that perspective it seems questionable if all toolchains are able to optimize away the overhead imposed by an "unnecessary" indirection to access uip_buf - and uIP consists mostly of accesses to uip_buf. Even if the future is supposed to bring support for multiple uip_bufs which would turn the uip_buf pointer from a mere workaround to an neceesary element on can still presume that there will be targets with resources limited in a way prohibiting the use of several uip_bufs. So at least for those targets will still be a usecase for a "plain", not indirected uip_buf.
...
Therefore it seems reasonable to allow to stay with the "plain" uip_buf at compile-time.

Bugfix: Active TCP connections in uIP are made by first setting up the

TCP connection state, then poll uIP to send out the first SYN. Until
now, however, the SYN was not sent as part of the poll, but at the
first retransmission. This is now fixed.

Change typedef of uip_ipaddr_t from a vector type to a union.
...
typedef union uip_ip4addr_t {
u16_t u16[2];
u8_t u8[4];
} uip_ip4addr_t;
typedef uip_ip4addr_t uip_ipaddr_t;
This implies that one must consistently pass pointers to
uip_ipaddr_t:s and not mix and match pointers with
uip_ipaddr_t:s as was done earlier.
