src: add synproxy stateful object support
Add support for "synproxy" stateful object. For example (for TCP port 80 and
using maps with saddr):
table ip foo {
synproxy https-synproxy {
mss 1460
wscale 7
timestamp sack-perm
}
synproxy other-synproxy {
mss 1460
wscale 5
}
chain bar {
tcp dport 80 synproxy name "https-synproxy"
synproxy name ip saddr map { 192.168.1.0/24 : "https-synproxy", 192.168.2.0/24 : "other-synproxy" }
}
}
