slirp/arp_table.c: Avoid shifting into sign bit of signed integers

"0xf << 28" shifts right into the sign bit, since 0xf is a signed
integer. Use the 'U' suffix to force an unsigned shift to avoid
this undefined behaviour and a clang sanitizer warning.

slirp: Don't crash on packets from 0.0.0.0/8.

LWIP can generate packets with a source of 0.0.0.0, which triggers an
assertion failure in arp_table_add(). Instead of crashing, simply return
to avoid adding an invalid ARP table entry.

slirp: Fix types of IP address parameters

Should be uint32_t for IPv4, not int. Also avoid in_addr_t without
proper includes. Fixes build regression on mingw32.

This patch adds a simple ARP table in Slirp and also adds handling of
gratuitous ARP requests.
