33fc20cca2 PPP: use mbed TLS sanitize functions if available 
mbed TLS offers sanitize functions to zero-ise memory containing
cryptographic keys, use them if built with external mbed TLS library.

3417a02b25 PPP: add a function map for hashes and ciphers to prepare for mbed TLS support 
Unfortunately, all functions were renamed when PolarSSL was renamed to
mbed TLS, breaking the API. In order to continue supporting our embedded
PolarSSL copy while allowing our users to use mbed TLS, we need a function
map to deal with the API break.

This commit add a function map for all hashes and ciphers we are currently
using.

2350d941a5 PPP, added PPP_USE_PBUF_RAM compile time option 
pbuf_type PPP is using for LCP, PAP, CHAP, EAP, IPCP and IP6CP packets.

Memory allocated must be single buffered for PPP to works, it requires pbuf
that are not going to be chained when allocated. This requires setting
PBUF_POOL_BUFSIZE to at least 512 bytes, which is quite huge for small systems.

Setting PPP_USE_PBUF_RAM to 1 makes PPP use memory from heap where continuous
buffers are required, allowing you to use a smaller PBUF_POOL_BUFSIZE.

045ee53468 PPP, using PBUF_POOL instead of PBUF_RAM pbufs for PPP negociation packets 
PPP stack does not handle chained pbuf, but PPP negociation packets
are at most ~40 bytes long, so we are only checking if the payload
can fit into the allocated pbuf (p->tot_len == p->len).

8b866beaeb demand support is now a compile-time option 
Obviously, it requires some wiring to know if there is new activity
on a not-yet established PPP interface with the default route
already set.

I don't think any lwIP user will ever need that, all should know
when to bring the link up and down.
