bf1285e3c9 ppp: don't link debug functions if disable 
This converts all ppp_*() debug functions to ppp_*(()) macros that
ensure the code is left out by the linker if the corresponding debug
setting is disabled.

Downside is that many lines of code are touched, but since these
already differ to upstream PPP sources, I figured that's ok...

See bug #55199

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.

fc7e327d19 PPP, MSCHAP, CCP, MPPE: reworked key passing from CCP to MPPE 
Removed mutiple copies of keys by pre-setting MPPE keys during MSCHAP
negotiation.

Improved MPPE init so we don't need to pass a buffer formatted in a
special way to MPPE, this is necessary for pppd to talk to the kernel,
we don't need that here.

3862aad2f7 PPP, MSCHAP, reworked local functions and constants 
MSCHAP was written the old-way, with all functions declared non static in

constants. Reworked in a more mordern way.

ab46ac9bd8 PPP, CHAP, reworked to pass ppp_pcb pointer to CHAP childs (MD5, MSCHAP, MSCHAPv2) 
We are going to need ppp_pcb* in MSCHAP and MSCHAPv2 for MPPE for
int mppe_keys_set, u_char mppe_send_key and u_char mppe_recv_key
which are currently global variable which must be moved to ppp_pcb.

c268c5e07c Removed all stuff requiring encryption. 
OpenBSD DES require more than 70 kB of static memory.

The GNU libcrypt DES, for information, require more than 131 kB,
so this is probably the case with all non memory optimised DES.

PolarSSL only required 132 bytes of stack with some kB of .rodata
precomputed tables :-)

I personally don't need MS CHAP v1 or MS CHAP v2, and that was not
supported in the previous PPP port, so there is no regression,
I feel comfortable about removing those hard to port stuff.

If someone want to do the MS CHAP port, he first have to find or
do a small memory footprint DES implementation.
