This disables the leading spaces removal for block comments to
avoid changing well-formatted blocks.
Based on test with uncrusity 0.72.0+dfsg1-2 on Ubuntu 22.04, the
leading spaces of block comment lines are unexpectedly removed by
current version w/o this patch.

According to the qemu source code, hw/arm/virt.c.
The secure memory of the ARM Virt board is [0xe000000~0xf000000]
and the non-secure memory is configured as [0x40000000~0xffffffff].
We made the following adjustments based on the above virt board configuration

This patch supports listing configs for a given board like
- `tools/configure.sh -L sama5`
- `tools/configure.sh -L rv-virt`
- `tools/configure.sh -L virt`

I found `struct ipv*_nat_entry` is missing `_s` suffix, but the name is too long in some cases, so maybe `ipv*_nat_entry_t` could be better.

1. The critical section does not prevent task scheduling
2. If the critical section is in sched_lock, there is no need to check,
scheduling is not going to happen
3. If sched_lock is in the critical section, sched_unlock will also
trigger scheduling without waiting for the exit of the critical section
4. After exiting the critical section, if there is an interrupt,
the scheduling will be automatically triggered

Notes:
1. This version of NAT66 is a stateful one like NAT44, corresponding to Linux's MASQUERADE target of ip6tables. We can support stateless NAT66 & NPTv6 later by slightly modify the address & port selection logic (maybe just match the rules and skip the entry find).
2. We're using same flag `IFF_NAT` for both NAT44 & NAT66 to make control easier. Which means, if we enable NAT, both NAT44 & NAT66 will be enabled. If we don't want one of them, we can just disable that one in Kconfig.
3. Maybe we can accelerate the checksum adjustment by pre-calculate a difference of checksum, and apply it to each packet, instead of calling `net_chksum_adjust` each time. Just a thought, maybe do it later.
4. IP fragment segments on NAT66 connections are not supported yet.

To prepare for future IPv6 NAT functions.
- Rename common ipv4_nat_xxx to nat_xxx
- Move some common definitions into header

Using CSR name depends on compiler support heavily, but CSR
encoding does not have this problem. It also make it easy to
add new CSR support even if the compiler does not support.
Unify CSR access by using the CSR encoding macro.

This patch adds more debug related CSR definitions
to arch/risc-v/include/csr.h.
These definitions are from the RISC-V Debug Specification
Version 1.0 rc1 (https://github.com/riscv/riscv-debug-spec).

In order to ensure the detached thread obtain the correct return
value from pthread_join()/pthread_cancel(), the detached thread
will create joininfo to save the detached status after thread
destroyed. If there are too many of detached threads in the
process group, the joininfo will consume too much memory.
This is not friendly to embedded MCU devices.
This commit keep the semantics as #11898 was introduced,
will no longer save joininfo for detached threads to avoid wasting memory.
