191836845e udhcpc: support for -O <option>. 
Two important notes:
* nissrv and nisdomain are not requested by default anymore!
* inconsistency between "XXXsvr" and "XXsrv" in option names resolved,
  all are "XXXsrv" now.

4c13922961 Introduce FEATURE_COPYBUF_KB. 
People who want smaller stack at any cost may use it
to reduce cp's stack usage (FEATURE_COPYBUF_KB=1).
Desktop people may get faster copy of big files
(FEATURE_COPYBUF_KB=32 is ~30% faster than 4kb)

186c2b3d0e iproute: fix a bug where "ip r flush table main" was rejected,

Add a few comments and stop mixing params and params' keywords.
