Before hooking up the MMU driver code to the Zephyr MMU core code it's
better to match the expected variable types of the two parts.

The MMU code is currently assuming that Zephyr only uses one single set
of page tables shared by kernel and user threads. This could possibly be
not longer true in the future when multiple set of page tables can be
present and swapped at run-time.
With this patch a new arm_mmu_ptables struct is introduced that is used
to host a buffer pointing to the memory region containing the page
tables and the helper variables used to manage the page tables. This new
struct is then used by the ARM64 MMU code instead of assuming that the
kernel page tables are the only ones present.

The net_timeout structure is documented to exist because of behavior
that is no longer true, i.e. that `k_delayed_work_submit()` supports
only delays up to INT32_MAX milliseconds. Nonetheless, use of 32-bit
timestamps within the work handlers mean the restriction is still
present.
This infrastructure is currently used for two timers with long
durations:
* address for IPv6 addresses
* prefix for IPv6 prefixes
The handling of rollover was subtly different between these: address
wraps reset the start time while prefix wraps did not.
The calculation of remaining time in ipv6_nbr was incorrect when the
original requested time in seconds was a multiple of
NET_TIMEOUT_MAX_VALUE: the remainder value would be zero while the
wrap counter was positive, causing the calculation to indicate no time
remained.
The maximum value was set to allow a 100 ms latency between elapse of
the deadline and assessment of a given timer, but detection of
rollover assumed that the captured time in the work handler was
precisely the expected deadline, which is unlikely to be true. Use of
the shared system work queue also risks observed latency exceeding 100
ms. These calculations could produce delays to next event that
exceeded the maximum delay, which introduced special cases.
Refactor so all operations that use this structure are encapsulated
into API that is documented and has a full-coverage unit test. Switch
to the standard mechanism of detecting completed deadlines by
calculating the signed difference between the deadline and the current
time, which eliminates some special cases.
Uniformly rely on the scanning the set of timers to determine the next
deadline, rather than assuming that the most recent update is always
next.

Adds a new family of `struct net_buf` operations that remove data from
the end of the buffer.
The semantics of `net_buf_remove_mem` have been chosen to match those of
`net_buf_pull_mem`, i.e. the return value is a pointer to the memory
that was removed.
The opposite of this function, `net_buf_remove`, would need to return
the old end of the data buffer to be useful. However this value is
always an invalid target for reading or writing data to (It points to
the middle of unused data).The existance of the function would be
misleading, therefore it is not implemented.

Document limitations on the FIFO queuing functions when fragments are
used. Namely that the `get` functions are not thread-safe when fragments
are present.
This is due to multiple independent calls to `k_fifo_get/sys_slist_get`.
A second thread can interrupt the retrieval before all fragments have
been removed. The second thread can then read from the FIFO, obtaining
the trailing fragments as a 'new' `net_buf`. The first thread will then
either assert or pull in the next `net_buf` on the queue as part of the
first `net_buf`.
