* Attempt to fix insufficient extract_name buffer
Some fuzzing failures happen because extract_name always uses in real
dnsmasq code daemon->namebuff of size at least MAXDNAME. Provide long
enough data also to fuzzed functions.
* Add myself as an interested party
Being dnsmasq maintainer in Fedora project and RHEL, I am interested in
new found failures. Especially when security related.
* Allocate full dhcp packet buffer
fuzz_dhcp can fail in clear packet. But that fails, because clear packet
always cleans whole buffer of maximal DHCP packet. But fuzzer allocates
less. Fix fuzzer to allocate similar memory as dhcp_common_init()
function of real dnsmasq.
