CCP might negotiate to not compress if peers cannot agree on a
compressor, therefore if the null compressor is chosen we must pass
packets as is instead of dropping them.

- SNMPv2c support
- Greatly reduced RAM usage, no memory pools any more
- API cleanup
- MIB2 is separated from SNMP stack
- Support for multiple MIBs (snmp_set_mibs call) - e.g. for private MIB
- Improved MIB2 implementation (tcpConnTable etc.)
- Redesigned simple and generic API for MIB implementation
- Comfortable node types for scalar arrays and tables
- Counter64, bit and truthvalue datatype support
- Callbacks for SNMP writes
- Runs on two APIs: RAW and netconn
- Async API is gone - the stack now supports netconn API instead,
so blocking operations can be done in MIB calls.
SNMP runs in a worker thread when netconn API is used.
- Simplified thread sync support for MIBs - useful when MIBs
need to access variables shared with other threads without locking
(used in MIB2 to access lwIP stats from lwIP thread)
Currently in work:
- Traps rewrite
- MIB compiler
Problem is that declaring functions as static in a public header will produce warnings in every file it is included because the static functions are not implemented.
Solution: When socket api is enabled, netconn is simply available, too
(Socket api uses netconn api internally)
LWIP_NETCONN and LWIP_SOCKET are defined in opt.h,
so move #include "lwip/opt.h" out of #if LWIP_NETCONN || LWIP_SOCKET guard.

This commit updates the snd_queuelen comment documentation to reflect
that snd_queuelen tracks the number of pbufs currently in the send
buffer (unsent + unacked queues) rather than the number of pbufs
available in the buffer (which was what previous comment implied)
This commit updates socket option comments to reflect which ones are
currently supported:
* SO_REUSEPORT is no longer implemented
* SO_SNDTIMEO is implemented
