d63a36e0f3 toos/gdb/thread:Support thread command on nuttx
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'

adc5c8b5ac Debug:support python script auto debug nuttx kernel
This patch add an example and pyhton base modules:
1.add memdump.py is an example to analyze memory
usage by python script.
2.add The most basic data structure analysis, like list, etc.

future ideas:
Maybe we can add modules related to "sched, drivers, arch, fs.." to
automatically analyze scripts to debug some problems
