replace uIP with adapted lwIP TCP stack (lwip_tcp)

- Replace uIP (src/uip/) with adapted lwIP 2.1.x TCP module
- Remove original src/lwip/ (replaced by src/lwip_tcp/)
- New src/lwip_tcp/ module: lwip_pbuf, lwip_tcp core/in/out
- Full TCP state machine, sliding window, congestion control
- Fast retransmit/recovery, Van Jacobson RTT estimation
- Nagle algorithm (TF_NODELAY), delayed ACK
- OOSEQ reassembly, TIME-WAIT handling
- Memory: memory_pool for PCB, listen PCB, tcp_seg
- Timers: uasync periodic timer drives fast/slow timers
- Output: callback-based IP packet output (TUN/raw-fd)
- Error codes: LERR_ prefix to avoid conflicts
- pbuf: simplified PBUF_RAM with proper header space reservation
- Integrate into tcp_proxy.c/h with per-pcb callbacks
- Active connection API: struct proxy_conn* instead of int conn_idx
- Makefile: remove uip, add lwip_tcp files
- test_tcp_proxy updated for new API; test_tcp_proxy_remote disabled
- Known: test_tcp_proxy data transfer needs flow tuning (WIP)

add UDP/ICMP proxy, refactor tcp_proxy via_node to instance-level

- UDP proxy: datagram relay client↔exit over ETCP
- ICMP proxy: echo ping relay client↔exit over ETCP
- Move via_node_id from per-forward-mapping to global tcp_proxy setting
- Support multiple concurrent tcp_proxy instances (no singleton g_tcp_proxy)
- Cap handshake padding to stay within 1472+overhead
- Handle non-TCP packets (UDP/ICMP) in tcp_proxy raw/tun input paths
- Add utun_instance_create_from_str() for test config creation
