tools/nuttx-gdbinit: improve experience of gdb backend scripts
Redefine built-in command (info thread/thread/c) to compatible with developer habits
Test board:
./tools/configure.sh -E lm3s6965-ek:qemu-flat
1. start qemu:
qemu-system-arm -M lm3s6965evb -device loader,file=nuttx -serial mon:stdio -nographic -s
2. gdb attach:
gdb-multiarch -ix tools/nuttx-gdbinit nuttx -ex "target extended-remote localhost:1234"
3. show thread info and callstack:

tools/nuttx-gdbinit: improve experience of gdb backend scripts
Redefine built-in command (info thread/thread/c) to compatible with developer habits
Test board:
./tools/configure.sh -E lm3s6965-ek:qemu-flat
1. start qemu:
qemu-system-arm -M lm3s6965evb -device loader,file=nuttx -serial mon:stdio -nographic -s
2. gdb attach:
gdb-multiarch -ix tools/nuttx-gdbinit nuttx -ex "target extended-remote localhost:1234"
3. show thread info and callstack:
