Summary:
- The NuttX sim SMP uses SIGUSR1 for IPI
- However, gdb traps the signal by default
- With this commit, gdb just ignores this signal
Impact:
- NuttX sim SMP only
Testing:
- Tested with sim:smp

Summary:
- Brennan reported the script does not work with nucleo-h743zi:otg_fs_host
- Actually, the config uses FPU but the script did not detect it
- The script assumed that the nuttx contains fpuconfig symbol
- However, this assumption was incorrect
- This commit fixes this issue by detecting FPU with tcb->xcp.regs
Impact:
- Cortex-M targets
Testing:
- Tested with lm3s6965-ek:discover (Cortex-M3)
- Tested with spresense:wifi_smp (Cortex-M4F)
- Tested with sim:smp (x86_64)

Summary:
- I noticed that call stack for Cortex-M3 was incorrect
- This commit fixes this issue
Impact:
- Affects nuttx-gdbinit for armv7-m without FPU
Testing:
- Tested with lm3s6965-ek:discover (qemu)
- Tested with spresense:wifi
- Tested with sim

Summary:
- This commit enables nuttx thread debugging without openocd-nuttx
- To use this script, gdb must support python
- To show all thread, use 'info_nxthreads'
- To switch thread, use 'nxthread pid'
- To continue, use 'nxcontinue'
Impact:
- No impact
Testing:
- Tested with spresense (Cortex-M4F), sim (x86_64), lm3s6965-ek (Cortex-M3)
- Tested with GNU Tools for Arm Embedded Processors 9-2019-q4-major
- Tested with GNU gdb (Ubuntu 8.1-0ubuntu3.2) 8.1.0.20180409-git
