There're some apps trying to set too large SO_SNDBUF and SO_RCVBUF, which may use all IOBs in one socket and block all other network traffic.
Note:
Linux silently limits SO_SNDBUF to be less than `sysctl_wmem_max`, so we can also do this limit without returning any error.

With double value=3.141593 initialized in va_list ap,
such code:
vsnprintf(buffer, sizeof(buffer), "%#.0f", ap);
expected output string: "3."
but real output string: ".3"

This small fix ensures all DMA pointers are correctly reseted during
DMA setup (when the driver is opened). Without this there could be rare
occurrence of driver pointer to incorrect (invalidate) DMA buffer and thus
saving incorrect characters to upper layer.

Circular buffer does not use DMA linked list therefore function
sam_freelinklist() cannot be called as it would fail on assertion (csa
not defined). Peripheral that calls DMA should care of buffer invalidation
instead.

EALREADY:
Both Linux(asm-generic/errno.h) and FreeBSD(sys/sys/errno.h) regard it as "Operation already in progress"
ESTALE:
Linux specifically removed the "NFS" description, and we may not only use it for NFS
0ca4343518
The ECANCELED and EOWNERDEAD also use different strings from Linux's header, but their meanings are same, and NuttX's description are more likely to obey POSIX 1003.1-2008, so not changing them.

1. the lio_sigsetup() method use a universal sighand instance across all
aiocb instances, but inside the lio_sighandler() method, if one aiocb is
handle finished, then this method will free the sighand instance that
come along with current aiocb instance. thus when handle next aiocb
instance, use-after-free crash will happen. in order to solve this
problem, we make each aiocb instance have their own sighand instance
2. make the lio_listio implementation can pass the
ltp/open_posix_testsuite/lio_listio testcases
3. the modification are referred to https://pubs.opengroup.org/onlinepubs/9699919799/functions/lio_listio.html

Port based on arch/arm/nrf53.
Modem not fully supported yet. At the moment, initialization and AT interface work.
Sockets and GNSS interface will be added later.
There is no need to use global spinlock to protect netdev
specific data counters. Allocate per-netdev specific spinlock
to get better locking granularity.
Move C/C++ atomic support checking to compiler.h

RISC-V ISA updates
Compared to previous releases, starting from 12.x, the compiler implements the new RISC-V ISA, which introduces an incompatibility issue, and builds might throw error messages like unrecognized opcode csrr.
The reason is that csr read/write (csrr*/csrw*) instructions and fence.i instruction were separated from the I extension, becoming two standalone extensions: Zicsr and Zifencei.
The solution is to add _zicsr and/or _zifencei to the -march option, e.g. -march=rv32imac becomes -march=rv32imac_zicsr_zifencei.
Summary:
- Some network drivers such as GS2200M do not support to bind
a local port for TCP client socket. In this case, this config
disables to bind the port.
- See also https://github.com/apache/nuttx/pull/3707
Impact:
- None
Testing:
- Tested with spresense:wifi_smp (Kconfig will be updated later)
- Tested with sabre-6quad:netnsh_smp (QEMU)

Summary:
- I noticed that virtio-blk and FAT are not enabled for some
virt configurations.
- This commit enables them for testing.
Impact:
- None
Testing:
- Tested with qemu-7.1
- NOTE: file copy with rv-virt:knetnsh64 is sometimes unstable.
