Created (a new) PPP interface for PPP service. Removed lwip
dependencies to PPP (memory allocations etc.). Moved PPP
configuration options away from lwIP mbed_lib.json to new
PPP service. For backwards compatibility, using the old
options is also currently supported.
Applied missing LWIP patch to PPP/utils.c
