What protocols init functions are meant to is to be called once to set
the default configuration before user specific configuration is set.
Until now, we reset to the default configuration just before
reconnecting, thus without allowing any time frame to let users change
it. That was fine until one user asked to be able to do that.
This change move protocols init functions calls from ppp_clear to
ppp_new, meaning user configuration is not overwritten anymore.
ccp_init() is meant to be called once, providing default configuration
before user specific configuration is applied. In pppd user configuration
is set just after all protocol init functions are called, in lwIP we
use protocol reset functions to do that, which is more or less the same.
Therefore, be consistent and move CCP user configuration from ccp_init
to ccp_resetci.
Use LWIP_ARRAYSIZE to simplify the code.

We need to know which methods were chosen when CCP is up, this used to be done
using ccp_test() which we are in the process of removing.
Using non-existing method 0 instead of -1 in CCP for unset method, allowing
type change from s16_t to u8_t for method.
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.
ccp_test() is not only used to test kernel support, but also to set MPPE keys,
we will change that further, but for now, re-add the necessary ccp_test()
We don't need to test our available compression protocols that much, we know
what we are going to be able to use in embedded. Even PPPd don't need that.
Checking only in ccp_resetci() is enough, this way we know our cilen size
before ccp_addci() is called. PPPd is designed that *_addci() can use less
bytes than it previously asked in *_cilen(), we prefer to avoid that here.
We actually don't need at all ccp_test() calls, we know what we are
able to support at compile time, we don't need to ask the kernel like
PPPd does. This is just the first step in ccp_test() removal.
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.
Removed all the used Linux ioctl(), sys_linux.c is entirely disabled.
Replaced unecessary functions to set up a PPP link to null fonctions,
however all stuff necessary to shutdown a PPP link should be done.
Some utils functions related to I/O files are disabled too.
ECP and CCP support only set PPP attributes into the PPP kernel support,
they are now compile-time options and are disabled by default and
obviously not supported (yet? :p)
