If we the stored RPL entry was for an old IV Index, and the received
PDU is for a new IV Index we should not be comparing the sequence
number (as it's by definition always greater than the old one).

Section 4.2.11 of the Mesh Profile Specification 1.0 states:
"Upon transition from GATT Proxy state 0x01 to GATT Proxy state 0x00
the GATT Bearer Server shall disconnect all GATT Bearer Clients."
This also makes test case MESH/SR/MPXS/BV-08-C pass.

Section 4.2.11.1 of the Mesh Profile specification 1.0 states:
"When the GATT Proxy state is set to 0x00, the Node Identity state for
all subnets shall be set to 0x00 and shall not be changed."
When the proxy state has been changed we also need to wake up the
advertising module to make sure we do the right kind of advertising.

Section 3.4.5.2 in the Mesh Profile Specification (1.0) states:
"The output filter of the interface connected to advertising or GATT
bearers shall drop all messages with TTL value set to 1."
Also: https://www.bluetooth.org/errata/errata_view.cfm?errata_id=9811
Note that this is specifically 1 and not 0, since e.g. Friend PDUs
always go out with TTL 0.
Another noteworthy thing is that the way this has to be implemented is
slightly contrary to how it's presented in the specification (both in
the text as well as the Message processing flow diagram in section
3.11. If this was implemented following the spec to its word, then any
PDU received over GATT or Advertising with TTL 2 would never be
relayed (since the TTL would be 1 when the PDU gets rerouted back to
the bearer). This would be both counterintuitive to the intended
purpose of the TTL, and would also be contrary to the test
specification (see Test Procedure step 1 in MESH/NODE/RLY/BV-01-C).

According to yaml syntaxic rules, 'properties' described in dts
bindings yaml files could be seen as 'mapping'(key/value couple),
instead of 'series' (list of single elements).
yaml 'mappings' will then be converted by yaml python library as
python 'dict' which will ease treatment (instead of current list
as were before this commit).
Same treatment is applied to 'inherits'.
script extract_dts_inlcude is updated to take change of yaml_list
structre into account. This allows some code simplification. Largest
impact is yaml_collapse function which works now allow complete

This is still work-in-progress, but putting it up in case it is
helpful to people working in this area and for early comments.
Add a set of tests to validate the expected security properties
of threads created with K_USER when CONFIG_USERSPACE=y. This can
be used as a regression test for architectures that already implement
this support and as a validation test for others.
I considered incorporating these tests into the existing protection
test, but decided against it since protection does not enable or rely
upon CONFIG_USERSPACE for its existing tests and passes on everything
that provides MPU or MMU support, even without full userspace support.
I also considered incorporating these tests into the existing
obj_validation test, but decided against it since obj_validation only
tests the object validation/permission logic, does not run any user
mode threads (or strictly depend on that support), and passes
on both x86 and arm today, unlike these tests. That said, I have no
strong objections if it would be preferable to fold these into it
(and perhaps rename it to be more general).
The current tests implemented in this test program verify the following
for a thread created with K_USER:
is_usermode: is running in usermode
priv_insn: cannot invoke privileged insns directly
write_control: cannot write to control registers
disable_mmu_mpu: cannot disable memory protections (MMU/MPU)
read_kernram: cannot read from kernel RAM
write_kernram: cannot write to kernel RAM
write_kernro: cannot write to kernel rodata
write_kerntext: cannot write to kernel text
read_kernel_data: cannot read __kernel-marked data
write_kernel_data: cannot write __kernel-marked data
read_kernel_stack: cannot read the kernel/privileged stack
write_kernel_stack: cannot write the kernel/privileged stack
pass_user_object: cannot pass a non-kernel object to a syscall
pass_noperms_object: cannot pass an object to a syscall without a grant
start_kernel_thread: cannot start a kernel (non-user) thread
Some of the tests overlap and could possibly be dropped, but it
seems harmless to retain them. The particular targets of read/write
tests are arbitrary other than meeting the test criteria and can be
changed (e.g. in data, rodata, or text) if desired to avoid coupling
to kernel implementation details that may change in the future.
On qemu_x86, all of the tests pass. And, if you replace all
occurrences of ztest_user_unit_test() with ztest_unit_test(), then
all of the tests fail (i.e. when the tests are run in kernel mode,
they all fail as expected). On frdm_k64f presently (w/o the arm
userspace patches), all of the tests fail except for write_kernro and
write_kerntext, as expected.
ToDo:
- Verify that a user thread cannot access data in another memory domain.
- Verify that a user thread cannot access another thread's stack.
- Verify that a user thread cannot access another thread's kobject.
- Verify that k_thread_user_mode_enter() transitions correctly.
- Verify that k_object_access_revoke() is enforced.
- Verify that syscalls return to user mode upon completion.
- Verify that a user thread cannot abuse other svc calls (ARM-specific).
- Other suggested properties we should be testing?

There were several issues with the code:
- queue_size wasn't properly kept up to date, leading to erroneous
buffer discarding logic.
- Poll timeout when there were buffers in the Friend Queue didn't
work because we didn't track if there'd been a preceding request
for messages or not (hence the added pending_req variable).
- We would overwrite the recv_delay timer if there was another
request while the previous one was still sending (a likely scenario
if we send out multiple advertising events per packet).
- We weren't canceling the sending of a buffer if the Friendship was
suddenly cleared.

Pass the subnet to some friend_cred_* APIs since it contains all
necessary information for choosing the right keys to generate them
from. Also shorten the API names to avoid awkward line splitting -
these are internal APIs so it's an acceptable compromise. One bug that
this fixes as part of the cleanup is using the right NetKey Index when
clearing Friendship: previously the code was always using the index of
the first subnet, regardless of which subnet the Friendship was based
on.

The shell was being inconsistent in its parsing of boolean parameters.
Some commands were documented as accepting "on" but were actually
parsing the parameter with strtoul() which would result in 0.
Introduce a new helper to convert a string to a u8_t which still
accepts "on" or "enable". This gives us full flexibility of having a
simple interface to the user, but still allowing non-boolean values to
be tested (since on-air the value is a full octet).
