This commit fixes the regression from https://github.com/apache/nuttx/pull/13561
In order to determine whether a context switch has occurred,
we can use g_running_task to store the current regs.
This allows us to compare the current register state with the previously
stored state to identify if a context switch has taken place.

The reason is that libc.h needs to check whether CONFIG is enabled before the corresponding macro is enabled

The FIOC_FILEPATH ioctl call is required if smartfs is to be used
together with inotify monitoring system. This implements the
call support to smartfs file system. The path to the file has to
be stored in smartfs_ofile_s structure during file open (and is freed
during close) as smartfs currently is not able to obtain the path
knowing only the file node. The full path is concatenated with the file
name and creates the full path needed for inotify to detect whether
the file is on the watchlist.

We need to record the parent's integer register context upon exception
entry to a separate non-volatile area. Why?
Because xcp.regs can move due to a context switch within the fork() system
call, be it either via interrupt or a synchronization point.
Fix this by adding a "sregs" area where the saved user context is placed.
The critical section within fork() is also unnecessary.
There was an error in the fork() routine when system calls are in use:
the child context is saved on the child's user stack, which is incorrect,
the context must be saved on the kernel stack instead.
The result is a full system crash if (when) the child executes on a
different CPU which does not have the same MMU mappings active.
Add support for etc files with absolute paths
usages:
```
add_board_rcsrcs(${CMAKE_CURRENT_SOURCE_DIR}/etc/build.prop)

for the citimon stats:

enter_critical (t0)

thread running
IRQ happen, in ISR:
post thread0
up_switch_context
note resume thread0 (t2)
ISR continue f1
ISR continue f2
...
ISR continue fn
leave_critical (t3)
You will see, the thread 0, critical_section time is:
(t1 - t0) + (t3 - t2)
BUT, this result contains f1 f2 .. fn time spent, it is wrong
to tell user thead0 hold the critical lots of time but actually
not belong to it.
Resolve:
change the nxsched_suspend/resume_scheduler to real hanppends
