bf03bb557f support gdbstub use serial.
we can use uart to debug nuttx,like debugger:

1. read/write memory
2. Use watchpoint,breakpoint,single step.
    use up_debugpoint api

3. Ctrl+c to stop, continue, or single step.
    hold uart send and receive

4. register a panic event, when crash or assert/panic, we use uart to
   debug.

749655d785 tcbinfo:remove total_num form tcbinfo.
total_num is not required
test:

make -f tools/Makefile.host
cp tools/jlink-nuttx /opt/SEGGER/JLink_V786a/libnuttxplugin.so
JLinkGDBServer -if SWD -speed 5000 -device STM32F429ZI -NoGui 1 -rtos libnuttxplugin

can run normally

b956495c5e libs/libc:Support gdb rsp protocol
you can debug nuttx through any transport layer (serial port, network etc.),
currently supports the following functions:
1. Read and write registers
2. Read and write memory
3. Switch thread and read stack information

Future support plans:
1. Support breakpoint, watch point (requires architecture support).
