1. Tcp will idle loop by tcp_timer when have no packet to send. This will cause low-power devices to be frequently woken up.
2. We should add tcp_timer when timer has been canceled and have packet to send.

if dev->d_flags is POLICY_1, the circbuf cannot be initialized incorrectly.
We determine whether the circbuf should be initialized based on first reference on device and d_buffer is NULL

For udp localsocket current implementation,the sent information only carries the packet info.
The receiver receives the information,it don't know who the information comes from.
Thus the receiver doesn't know who to send the response message to.
We add sender's binding path info in the information,the receiver knows who sent the information
based on the parsed information.
The receiver knows who to send the response message to.

From the current implementation,udp localsoket receiver's pipe is closed, the sender write failed in the pipe;
we change the implementation to check if buffer is free(PIPE_IS_POLICY_0),if not free,the sender could write in the pipe;
From the current implementation,udp localsoket sender's pipe is empty,the recevier directly return end of file;

Then, you will see the pipe hasn't free its resource, memleak
Resolve:

(2) if iv not provided during decryption, iv should get from data.
It was not discovered before because all symmetric decryption comes with iv.

This is the initial version for kernel mode build on the arm64 platform.
It works much in the same way as the risc-v implementation so any
highlights can be read from there.
Features that have been tested working:
- Creating address environments
- Loading init (nsh) from elf file
- Booting to nsh
- Starting other processes from nsh
- ostest runs to completion
Features that are not tested / do not work:
- SHM / shared memory support
- Kernel memory mapping (MM_KMAP)
- fork/vfork
An example qemu target is provided as a separate patch:
tools/configure.sh qemu-armv8a:knsh
Why? Because this allows optimizing the user system call path in such
a way that the parameter registers don't have to be read from the saved
integer register context when the system call is executed.

When a low-priority thread sends a kill signal to a high-priority thread,
the high-priority thread will exit and release tcb. When the thread returns
to the low-priority thread, it will access the released stcb.

Events groups are synchronization primitives that allow tasks to wait
for multiple conditions to be met before proceeding. They are particularly
useful in scenarios where a task needs to wait for several events to occur
simultaneously.
