Initially, there was support only for buffered input, and adhoc var
names used. Later, buffered output support was added, with variables
consistently using "tx_" prefix. Now, rename the original RX path
to use symmetric "rx_" prefix.

The nrf_rtc_timer used own method to calculate number of timer cycles
per tick. As the result value was different than the one used by
the kernel, the reported time was incorrect.
This commit fixes the problem described above by using global
sys_clock_hw_cycles_per_tick instead of custom RTC_TICKS_PER_SYS_TICK.

Functions for per-interface statistics collection used a pointer to a
packet that could've been deallocated in the net_conn callback function.
In result, application could crash when interface related to the packet
was referenced. To fix that, packet interface is stored earlier, so it
can be used instead for statistics collection.

Users are sometimes mistakenly invoking cmake with $ZEPHYR_BASE set as
the source directory.
This user-error can occur if the user believes that the toplevel
CMakeLists.txt file is at the root of the repo, or if the user uses
the wrong path when invoking cmake.
The error given when this user-error occurs is cryptic and undefined,
so we replace it with what should be an easy-to-understand error

The IP stack drops any TCP segment which doesn't fit into our
receive window. However, we still must accept Zero Window Probe
segments, which are segments, usually with data length of 1, which
a peer sends to us after we stayed with zero window for some time.
In this case, we need to repeat an ACK with the old ack number.

The _THREAD_POLLING bit in thread_state was never actually a
legitimate thread "state". It is a clever synchronization trick
introduced to allow the thread to release the irq_lock while looping
over the input event array without dropping events.
Instead, make that flag a word in the "poller" struct that lives on
the stack of the thread calling k_poll. The disadvantage is the 4
bytes of thread space needed. Advantages:
+ Cleaner API, it's now internal to poll instead of being globally
visible.
+ The thread_state bit space is just one byte, and was almost full
already.
+ Smaller code to write/test a full word and not a bitfield
+ Words are atomic, so no need for one of irq lock/unlock pairs.

Symbols that are assigned values in .config files must have satisfied
dependencies, and must have a prompt. Otherwise, the assigned value is
ignored. A warning is printed if the symbol ends up with a different
value than the assigned value as a result.
It might be difficult to know how to fix the problem just from seeing
the current warning. Add some hints to it to help out:
- The symbol information dialog in menuconfig is good for figuring out
dependencies that need to be enabled. Mention menuconfig in the
warning.
- The page for the symbol in the autogenerated Kconfig docs can be
helpful too, so link it. There's a slight chance that it'll be
outdated, but it's usually correct when working on the master
branch.
Automatically enabling dependencies is much trickier than it might seem
at first, due to the generality of Kconfig. See
https://github.com/zephyrproject-rtos/zephyr/issues/8181 for some
discussion.

It's rather confusing to not see current TCP state in any way (it
makes distinguishing different TCP contexts very hard). And nobody
can know/remember that it's printed with CONFIG_NET_DEBUG_TCP
defined. So, just make it be printed always (initially I thought
about printing just numeric value if CONFIG_NET_DEBUG_TCP isn't
defined, but why, if we can print symbolic name easily).
Also, add a hint that defining CONFIG_NET_DEBUG_TCP will still
print even more info (like unacked pkt list) - similarly to
similar helpful hints we have in other parts of net shell.

The queue loop when CONFIG_POLL is in used has an inherent race
between the return of k_poll() and the inspection of the list where no
lock can be held. Other contending readers of the same queue can
sneak in and steal the item out of the list before the current thread
gets to the sys_sflist_get() call, and the current loop will (if it
has a timeout) spuriously return NULL before the timeout expires.
It's not even a hard race to exercise. Consider three threads at
different priorities: High (which can be an ISR too), Mid, and Low:
1. Mid and Low both enter k_queue_get() and sleep inside k_poll() on
an empty queue.
2. High comes along and calls k_queue_insert(). The queue code then
wakes up Mid, and reschedules, but because High is still running Mid
doesn't get to run yet.
3. High inserts a SECOND item. The queue then unpends the next thread
in the list (Low), and readies it to run. But as before, it won't
be scheduled yet.
4. Now High sleeps (or if it's an interrupt, exits), and Mid gets to
run. It dequeues and returns the item it was delivered normally.
5. But Mid is still running! So it re-enters the loop it's sitting in
and calls k_queue_get() again, which sees and returns the second
item in the queue synchronously. Then it calls it a third time and
goes to sleep because the queue is empty.
6. Finally, Low wakes up to find an empty queue, and returns NULL
despite the fact that the timeout hadn't expired.
The fix is simple enough: check the timeout expiration inside the loop
so we don't return early.
