Obtaining the heap usage size requires traversing all memory.
When the number of threads is large, it will become very slow.

This commit introduces the timerjitter test case, designed for assessing timer accuracy quickly. It is a simplified cyclictest implementation, optimized for fast and effective testing of timer precision.
The program sets up a periodic timer and awaits the firing of SIGALRM. Upon signal arrived, it computes the time difference between consecutive periods. A smaller time difference indicates higher time accuracy.
You can execute timerjitter without passing any arguments. Alternatively, you have the option to pass '-p' to print the time difference after each period, or provide additional arguments to customize the timer interval (in microseconds) and the number of test iterations.

If BUILD_FLAT is not enabled, the app and CPU run in user mode and
kernel mode respectively. The kernel and app are in different
memory address spaces. Different apps are in the same memory address
space. drivertest_block.c cannot directly call the kernel API.

we can build a module like app,
use 'DYNLIB' mark current path is a loadable module
and CFLAGSELF and CMODFLAGS can act on
these compiled as loadable module

After thread switching is triggered in an interrupt, two notes will be printed.
If the buffer of 256 is not enough, it will cause overflow.

Summary:
Added a limit to CJSON_NESTING_LIMIT. The default value is 1000, which can cause stack overflow in some test cases.

sim:nsh
cat < /etc/init.d/rc.sysinit
Problem
The NSH hangs after exec the test command.
`nsh_redirect()` needs to save three fd but array length is only two, stack buffer overflowed!

We may want to test ramspeed by specific address, it was previous ignored,
and for the not aligned address from user, just report a error.
