There is a risk that interfaces such as psock_ioctl/psock_setsockopt
will cause paramete to be not four-byte aligned after calculating the
offset, so align the length of the structure with parameters by four
bytes.

File system CI test was not testing the correct behavior of scanf and just
checked whether program did not end with hard fault. This adds
functionality check and required configuration options to run FS test.

This commit adds support for custom stream via fopencookie function.
The function allows the programmer the create his own custom stream
for IO operations and hook his custom functions to it.
This is a non POSIX interface defined in Standard C library and implemented
according to it. The only difference is in usage of off_t instead of
off64_t. Programmer can use 64 bits offset if CONFIG_FS_LARGEFILE is
enabled. In that case off_t is defined as int64_t (int32_t otherwise).
Field fs_fd is removed from file_struct and fs_cookie is used instead
as a shared variable for file descriptor or user defined cookie.
The interface will be useful for future fmemopen implementation.

Summary:
- I noticed that irq is enabled explicitly in arm64_cpu_idle.S
- The code is unnecessary since tasks, including the idle task,
are created with irq enabled in up_initial_state()
Impact:
- Should be none
Testing:
- qemu-armv8a:netnsh_smp_hv with qemu-7.2.4

Support smp function call, calling smp_call_function allows
a specific core to execute a function. It should be noted
that there should be no waiting operations in the executed
function.

Fix case where NULL is de-referenced via tx/rx buffer or descriptor. Only
1 queue is currently set up for each, so the indices 1,2,3 are not valid
and should not be handled.
Before code is executed after being loaded into memory,
it is necessary to ensure the consistency of I and D cache.
The up_coherent_dcache function will flush the dache and
invalidate the icache to ensure cache consistency.

spinlock.c:
Implement read write spinlock.
Readers can take lock simultaneously but only one writer can take lock.
irq_spinlock.c:
Align g_irq_spin_count.
If the lock is NULL, the caller will get global lock (e.g. g_irq_spin) and spin_lock_irqsave() support nest on the same CPU.
If the CPU can write lock, it can call write_lock_irqsave() again (e.g. support nest).

In previous versions, during the teardown phase, the "open_blockdriver" would call the "mtd proxy" causing the "file mtd" node to be registered in the ftl. " node is registered in ftl.
Therefore, we changed the behavior to find the corresponding inode by node name.
