When a mempool is created with a large number of maximum-size blocks,
the logic for initializing max_inline_level (i.e. when to union the
bitmask with the pointer and when to use the pointer directly) was
wrong. The default state was "zero", which implies that level 0
should be inlined, but that's wrong with >32 base blocks.
Additionally, the type was unsigned, making the "level zero is a
pointer" situation impossible to represent.

This commit introduces a type definition for the ARM MPU
region attribute container. This allows to abstract the type
of the attribute container and make the code extendible for
ARMv8-M, where the size and structure of the attribute
container will be different.
Therefore, we can, now, move the definition of the region
data structure in the common arm_mpu.h header.

This enables reserving little space on the top of stack to store
data local to thread when CONFIG_USERSPACE. The first customer
of this is errno.
Note that ARC, due to how it lays out the user stack and
privilege stack, sets the pointer itself rather than
relying on the common way.

This rewrites the implementation of the APP_INPUT_SECTION and
KERNEL_INPUT_SECTION macros such that an unbounded amount of
kernelspace libraries can be used.
This resolves#7703
The new implementation has a caveat/limitation; the linker script
developer must invoke APP_INPUT_SECTION before KERNEL_INPUT_SECTION.
All in-tree linker scripts happened to already be doing this so no
in-tree porting was necessary.

Commit 2b8cf4c98e ("include: kernel: Fix documentation for
TICKLESS_KERNEL API's")' defined a macro to fix documentation when
TKCKLESS_KERNEL is not available but this macro does not return the
same the functions returns, so its use may result in compilation
error.
Another point to consider is that if one is using this function
without it be enabled is better to return a proper error like ENOTSUP
explicitly saying that this is not supported.

Some locations like DHCPv4 client create a prefilled packet by appending
new fragments in a loop with one byte each via net_pkt_append_u8() which
is wasteful and noisy. This patch adds the new functions
net_pkt_append_memset() which creates fragments as needed in the desired
size and initialises it to the specified value.
This change also adds a unittest for the new function.

There exist two symbols that became equivalent when PR #9383 was
merged; _SYSCALL_LIMIT and K_SYSCALL_LIMIT. This patch deprecates the
redundant _SYSCALL_LIMIT symbol.
_SYSCALL_LIMIT was initally introduced because before PR #9383 was
merged K_SYSCALL_LIMIT was an enum, which couldn't be included into
assembly files. PR #9383 converted it into a define, which can be
included into assembly files, making _SYSCALL_LIMIT redundant.
Likewise for _SYSCALL_BAD.
