Some time nuttx will receive SIGSEGV while executing the function:
| Thread 1 "nuttx" received signal SIGSEGV, Segmentation fault.
| 0xf7bab4a0 in __sanitizer::common_flags_dont_use () from /lib/i386-linux-gnu/libasan.so.6
| The program being debugged was signaled while in a function called from GDB.
| GDB has restored the context to what it was before the call.
| Evaluation of the expression containing the function
| (up_check_tcbstack) will be abandoned.

Summary:
- I noticed that nuttx-gdbinit does not work.
- Finally, I found that the g_pidhash had been changed recently.
- This commit fixes this issue.
Impact:
- None
Testing:
- Tested with lm3s6965-ek:discover (QEMU)

This checks if the required function is defined (when stack coloration
is enabled) and, if so, calls it to get used stack. Otherwise it just
reports zero used stack.
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
