Boris Popov 29ad26f932 Major update of NCP requester:
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.
