PPP: add a new LWIP_USE_EXTERNAL_POLARSSL PPP option

Browse Source 
In order to welcome mbed TLS, we need to ease the switch to:
    - embedded PolarSSL 0.10.1-bsd copy
or  - external PolarSSL
or  - external mbed TLS

This change cleanup all our previously used LWIP_INCLUDED_POLARSSL_* defines,
which were not really useful after all, making them internal build triggers
only, and this change provides a new unique global flag to use an external
PolarSSL copy.

------------------------------------------
This folder contains some files fetched from the latest BSD release of
the PolarSSL project for ciphers and encryption methods we need for lwIP
PPP support.
the PolarSSL project (PolarSSL 0.10.1-bsd) for ciphers and encryption
methods we need for lwIP PPP support.
The PolarSSL files were cleaned to contain only the necessary struct
fields and functions needed for lwIP.
The PolarSSL API was not changed at all, so if you are already using
PolarSSL you can choose to skip the compilation of the included PolarSSL
library into lwIP:
library into lwIP.
The following defines are available for flexibility:
LWIP_INCLUDED_POLARSSL_MD4 ; Use lwIP internal PolarSSL for MD4
LWIP_INCLUDED_POLARSSL_MD5 ; Use lwIP internal PolarSSL for MD5
LWIP_INCLUDED_POLARSSL_SHA1 ; Use lwIP internal PolarSSL for SHA1
LWIP_INCLUDED_POLARSSL_DES ; Use lwIP internal PolarSSL for DES
LWIP_INCLUDED_POLARSSL_ARC4 ; Use lwIP internal PolarSSL for ARC4
If set (=1), the default if required by another enabled PPP feature unless
explicitly set to 0, using included lwIP PolarSSL.
If clear (=0), not needed or using external PolarSSL.
If you are not using the embedded copy you must include external
libraries into your arch/cc.h port file.
Beware of the stack requirements which can be a lot larger if you are not
using our cleaned PolarSSL library.
