If the system clock is changed during loading gnssfw, gnss open may be
failed. So this commit prohibits clock change until loading gnssfw is
completed.
There is an issue that the next alarm is expired immediately after
canceling a RTC alarm. Fixed alarm settings to be completely cleared
when canceling an RTC alarm.
If the system clock is changed during the SPI transfer, the SPI data can
be corrupted. So this commit prohibits the clock change during SPI transfer,
and keep the clock until the transfer is completed.
Introduce PM_CPUFREQLOCK_FLAG_HOLD into the frequency lock mechanism in
power manager, which is used to keep the current frequency without clock
change, for example, during the transfer of a periphral.
UART driver is stopped and re-started during a clock change. When a UART
interrupt is generated in each process, the unexpected behavior will
occur and a console will get stuck with UART driver. This commit fixed
each process is performed atomically.

On an stm32 the heap is formed from
const uintptr_t g_idle_topstack = HEAP_BASE;
where HEAP_BASE is &_bss + CONFIG_IDLE_STACKSIZE.
Both these values are not deterministic. One
comes from the compiler, the other the system
configurator.
a 3 byte bss and 250 byte stack would lead to
and unaligned address used as the heap to be.
The compiler used clever `strd r1,r3,[r5,#8]` to
store 2 values in one memory cycle into the
heap_impl struct. Resulting in a hardfault.
Change the amount of bss or the CONFIG_IDLE_STACKSIZE
could lead to a non-functional NuttX system.
Fix bug that select() did not return when the nfds argument
was set to a negative value. The specification is that -1 is
set to the return value and EINVAL is set to errno.
When creating the next chain of directory entries, (1) add the position
of next entry to the current sector, and then (2) update the sector of
next entry. If the power is turned off between (1) and (2), the next
entry will not be found, and the chain of directory entries will break.
It causes the SmartFS file system corruption, and we will not be able
to add files.
To avoid this issue, in checking the filesystem by smart_fsck_directory,
if the sector of next entry does not exist, update the sector of
directory entry to invalidate the field of next entry.
If the current cluster is invalid, don't use the error code for calculating
the sector number. Instead just return the error code.

since emergstream always call syslog_force, but syslog_force is designed
for the interrupt context, and then doesn't mean any emergency thing.
On the other hand, emergstream has other bad side effect:
1.Can't output to file or dev channel
2.Can't work well with the interrupt buffer

the number of members in the group is zero.
Repetition step:
If using waitpid() to wait a task has exited, the waitpid will use
nxsing_kill with signal number 0 to determine if that task is still
alive, and will call group_signal to dispatch signal for each member
of the group and perform signal handing checks, it will assert at
sched/group/group_signal.c:261.
