Add a separate macro for registering offloaded sockets implementation,
along with information in the structure whether the implementation is
offloaded or not. This allows to differentiate between native and
offloaded socket implementations, which is critical for binding socket
API with an interface.

Instead of keeping a boolean informing whether a network interface is
offloaded at socket layer or not, keep a pointer to a function which
allows to create an offloaded socket. Native interfaces keep this as
NULL, while for offloaded interfaces it allows to connect an offloaded
socket implementation with an interface.

In 90c6dc5e7f, a change was introduced to
allow modem commands determine if they have enough data or not.
In a situation where some data is missing, the command should return
-EAGAIN and this should lead to another call of the command with more
data.
In this commit, the argument parser was also allowed to return -EAGAIN
to request more data due to missing arguments.
However, this can't work because in cmd_handler_process_rx_buf() before
calling process_cmd():
- we make sure that a CR/LF has been found.
- we compute match_len which can't be greater than the distance to the
next CR/LF.
Therefore, even if the command argument parser ask for more data by
returning -EAGAIN, next call will have the same value for match_len,
meaning that the parsing of argument will result in the same missing
argument situation.
This leads to an infinite loop of parsing the same data over and over in
an infinite loop.
This commit change this behavior to always drop the data in such a
situation. The command will not be answered and will therefore timeout,
but at least, next commands will correctly parse their returned data.

The driver should check for cellular registration before
attempting to attach to packet service, otherwise it will just

This patch waits for registration for 300 seconds, configurable
by CONFIG_MODEM_GSM_REGISTER_TIMEOUT, if it isn't registered by
then, it would toggle the airplane mode using AT+CFUN & wait
again, until it is registered, or `gsm_ppp_stop` is invoked.

The response of a KTCPSND has two phases. According to documentation by
wireless the timeout is 60 seconds. The fix respects the timeout on the
second phase, too (waiting for OK or errors from modem). Previously only
the first phase used 60 seconds and the second phase used 5 seconds.
Without this fix the hl7800 will lock the tcp stack for the current
socket indefinitely if another socket operation is performed before the
response from the modem is received.
Additionally all timeouts are adjusted to be at least one second longer
as the documented timeout from wireless. This avoids races between the
hl7800 and the driver.

The tx_lock timeout is closely related to GSM_CMD_AT_TIMEOUT
& GSM_CMD_SETUP_TIMEOUT, and should be longer than both of
them, otherwise the gsm_ppp_stop might fail to lock the tx.
Define the timeout at the top of the driver and added a comment
to make it clear for the user.

GSM_MUX. It uses the NET_MGMT_EVENT to signal a semaphore to
