net_frag_linearize() is just a wrapper for net_buf_linearize(). As
the latter was refactored to never return error, and instead just
return actual copied length, update the former and its usages too.
Signed-off-by: Paul Sokolovsky <paul.sokolovsky@linaro.org>
Don't try to find "errors" in the values of dst_len and len params
passed to net_buf_linearize(). Instead, do what entails with the
common sense from the values passed in, specifically:
1. Never read more than dst_len (or it would lead to buffer
overflow).
2. It's absolutely ok to read than specified by "len" param, that's
why this function returns number of bytes read in the first place.
The motivation for this change is that it's not useful with its
current behavior. For example, a number of Ethernet drivers linearize
a packet to send, but each does it with its own duplicated adhoc
routine, because net_buf_linearize() would just return error for the
natural use of:
net_buf_linearize(buf, sizeof(buf), pkt->frags, 0, sizeof(buf));

Currently OpenThread commands have to be prefixed in the shell by "ot
cmd", for example "ot cmd state". With the new shell, it is possible to
remove one subcommand level and change it to "ot state".
At the same time validate the number of arguments using
SHELL_CMD_ARG_REGISTER and improve the help message.

Following the introduction of the new shell, the OpenThread shell
wrapper is not well integrated. It outputs the answer to a command using
printk(), which is not necessarily using the same device than the shell
if "zephyr,console" does not match "zephyr,shell-uart".
OpenThread calls the otConsoleOutputCallback() function to output the
answer to the shell. It can provide a callback argument, but defined
when OpenThread is initialized, not when the command is submitted.
Workaround that by taking a copy of the shell argument in a static
variable and use it for the call to shell_fprintf(). It is not perfect
if two or more shells issue concurrent commands, but is already an
improvement compared to printk().

The net-shell "net allocs" command should print network buffer
allocations even if network packet debugging is not enabled.
This is how it used to work earlier but the behaviour got lost
at some point. So user needs to set CONFIG_NET_DEBUG_NET_PKT_ALLOC
in order to see the buffer allocations. The option will be enabled
by default if network packet log level is set to DBG.
The reason for a separate option is that the network packet debug
logging prints just too much data and it is very difficult to
track allocations when that happens.

As extend fdtable usage to more cases, there regularly arises a need
to forward ioctl/fcntl arguments to another ioctl vmethod, which is
complicated because it defined as taking variadic arguments. The only
portable solution is to convert variadic arguments to va_list at the
first point of entry from client code, and then pass va_list around.
To facilitate calling ioctl with variadic arguments from system code,
z_fdtable_call_ioctl() helper function is added.

It was weird to pre-parse ICMPv6 headers in IPv6. Moreover parsing
failure of such header would not generate the right statistic.
Instead, centralizing all into net_icmpv6_input relevantly, and adapting
the test cases which were using that function. In RPL test, removing the
dummy dio test was simpler since dio is anyway tested later on.

This commit reworks socket poll implementation to support multiple
socket implementations.
To achieve that, two ioctl poll helper requests were added:
ZFD_IOCTL_POLL_PREPARE and ZFD_IOCTL_POLL_UPDATE. The poll
implementation calls ioctl with these requests for each socket
requested in the fds table.
The first request is responsible for preparing k_poll_event objects
for specific socket. It can request to skip waiting in k_poll by
returning EALREADY through errno.
The latter request is responsible for processing outcome of k_poll for
each socket. It can request to retry the k_poll by returning EAGAIN
through errno.
