Use mchain API to work with mbuf chains. Do not depend on INET and IPX options. Allocate ncp_rq structure dynamically to prevent possible stack overflows. Let ncp_request() dispose control structure if request failed. Move all NCP wrappers to ncp_ncp.c file and all NCP request processing functions to ncp_rq.c file. Improve reconnection logic. Misc style fixes.
