It was not discovered before because all symmetric decryption comes with iv.

Some macro definitions have already been defined in other header files, redundant macro definitions have been removed in include/nuttx/can.h. Align some code. Remove no use struct (can_response_s) and some variables.

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.

below command to create mbim NIC on host
nsh> conn 3
NuttX's MBIM device implementation adds an additional MBIM network
card to the NuttX system, which can debug the data communication with
the host, but this network card is unnecessary and needs to be removed
when the business actually uses this driver, And the cdcncm_receive
method needs to be re-implemented.

Summary:
Indicate whether the file is currently locked by adding a new field locked to filep.
0 - Unlocked
1 - Locked
The status of the filep at close is used to determine whether to continue with the following procedure.
Optimizing performance:
Before
Time taken to close the file: 33984 nsec
After
Time taken to close the file: 23744 nsec
Improvement of about 10 msec

Summary:
Because stdio.h references stdatomic.h in MVSC, it internally declares mbstate_t, leading to redeclarations during compilation.
Signed-off-by: chenrun1 <chenrun1@xiaomi.com>
Summary:
This change mainly appears in the compilation environment of MVSC
Since MVSC supports the c++11 standard in VS2019 preview3 (https://en.cppreference.com/w/cpp/compiler_support/11), we can do static initialization using the c++11 approach

Summary:
1. use nuttx/atomic.h instead of stdatomic
2. remove CONFIG_HAVE_ATOMIC,because we now support atomic on all platforms

Summary:
1.Modify the conditions for entering different include header files
2.Added pre-definition for _Atomic _Bool when it is missing
3.Added nuttx for stdatomic implementation. When toolchain does not support atomic, use lib/stdatomic to implement it
