Introducing PPP dialup features to enable e.g. usage of nrf9160
based board as a dialup modem for transferring ip data over PPP
(e.g. windows dial up), i.e. usage of Zephyr PPP as a server for
providing MTU/MRU, IP address and DNS addresses for a PC:
- PPP LCP MRU option (configurable)
- PPP server: IPCP ip and dns address peer options to enable
providing IP and DNS addresses for PPP peer.

net_eth_carrier_on() and net_eth_carrier_off() call k_work_init() on
work item that can be pending or still be processed in another thread.
This results in undefined behavior.
Initialize work item once and use an atomic flag to switch between
up/down carrier state. Submit work to workqueue whenever up/down carrier
state changes, so that last state is always properly propagated to
network interface layer.
While at it, save network interface pointer during ethernet context
initialization, so that is becomes static (and thread-safe) during whole
ethernet context lifetime.

Currently there is no way to distinguish between a caller
explicitly asking for a semaphore with a limit that
happens to be `UINT_MAX` and a semaphore that just
has a limit "as large as possible".
Add `K_SEM_MAX_LIMIT`, currently defined to `UINT_MAX`, and akin
to `K_FOREVER` versus just passing some very large wait time.
In addition, the `k_sem_*` APIs were type-confused, where
the internal data structure was `uint32_t`, but the APIs took
and returned `unsigned int`. This changes the underlying data
structure to also use `unsigned int`, as changing the APIs
would be a (potentially) breaking change.
These changes are backwards-compatible, but it is strongly suggested
to take a quick scan for `k_sem_init` and `K_SEM_DEFINE` calls with
`UINT_MAX` (or `UINT32_MAX`) and replace them with `K_SEM_MAX_LIMIT`
where appropriate.

6lowpan over BLE should work without solicit node multicast messages
according to RFC7668[1], but that requires Neighbor Solicitation with
Address Registration Option, which is currently not implemented in
either Zephyr or Linux. This is causing the router to fallback to normal
neighbor solicitation based discovery, but the NS frames are being
discarded in the host stack because the solicit node multicast groups
are not registered.
This drops the NET_L2_MULTICAST_SKIP_JOIN_SOLICIT_NODE as a workaround
and adds a TODO about it.
