support arch:
sim x86
sim x86_64
arm32 all series
If we need to support more architectures in the future,
just add the 'g_tcbinfo' of the corresponding architecture
support thread command:
1. thread <id>
switch thread
2. info thread
list all thread info
3. thread apply [all | id list] command
like this:
thread apply all bt
thread apply all bt full
thread apply 1 2 4 bt
thread apply all info r
4. nxsetregs
Set registers to the specified values.
Usage: nxsetregs [regs]
Etc: nxsetregs
nxsetregs g_current_regs[0]
nxsetregs tcb->xcp.regs
Nxsetregs g_pidhash[0].tcb->xcp.regs
Default regs is g_current_regs[0],if regs is NULL,
it will not set registers.
Because NuttX enters exception_common during a crash,
this assembly function manipulates the stack pointer (sp),
causing GDB to be unable to trace back to the first context of the crash.
Instead, it shows the context of the interrupt stack. By using nxsetregs,
it is possible to forcefully set the first context to
the one before the interrupt occurred.
Notice:
Switching threads is achieved by setting registers,
so registers need to be restored before continue,
please use 'c' to continue instead of 'continue'

Also switch to automatic one by default, as it saves a lot of flash. The manual training
code is left in for now to be able to use it as an option if there are problems with automatic one

board/esp32s3/common is for common board driver. It should not
include a header file from specific board. so remove include
of esp32s3-devkit.h from some of the common driver source
The implementation of up_perf_*() is in a different static library in nuttx:
Hardware: libarch.a
Software: libdrivers.a (weak function)
Since functions with weak attributes cannot be correctly replaced in multiple static libraries,
this PR will use macros to replace whether the arch supports hardware perf events

If -fstack-protector-all is enabled, gcc linker will need GCC
SSP(Stack Smashing Protector) support, Since the implement of SSP
is related to the OS, most of embedded toolchain does not provide
ssp support, so an error will be reported when linking:
enable CONFIG_LTO_FULL && CONFIG_STACK_CANARIES
arm-none-eabi/bin/ld: cannot find -lssp_nonshared: No such file or directory
arm-none-eabi/bin/ld: cannot find -lssp: No such file or directory
https://github.com/gcc-mirror/gcc/blob/master/gcc/gcc.cc#L983-L985
Since nuttx has already implemented SSP related hook functions,
so in this PR, we filter out this option in the link phase to ensure that
the implementation of lssp/lssp_nonshared will not be referenced

When debugging the actual dns resolution failure encountered, it is found
that if you know the address of dnsserver, the difficulty of debugging the
problem is reduced.

according to https://github.com/apache/nuttx/pull/7903
it was to fix "the macOS runners occasionally failing".
cython issue workaround seems more important because it always fails.
- considering simplicity and design assumption, the reset function must work without flaw.
If it fails, there is no way to recover but to reset again. so checking return status does not
bring additional benefit
- There is unnecessary switch inside switch which is making code not too readable

When using IOB queue to store readahead data, we use one IOB for each
UDP packet. Then if the packets are very small, like 10Bytes per packet,
we'll use ~1600 IOBs just for 16KB recv buffer size, which is wasteful
and dangerous. So change conn->readahead to a single IOB chain like TCP.
Benefits:
- Using memory and IOBs more efficiently (small packets are common in
UDP)
Side effects:
- UDP recv buffer size may count the overhead
- A little bit drop in performance (<1%, more seek & copy)

Reading the CSD field misses 3 bytes as the residual bytes
are not carried over properly. Fix this by adding the missing
bytes due to shifting.
