Allow bootloader to select run-time whether the payload binary is booted with
SBI or directly by jumping to entrypoint address.
- Use just one bitmask to select sbi or direct boot for each hart
- Add mpfs_set_use_sbi function to allow selecting how to boot
- Initialize the bitmask by default according to the configuration flags
- Add a header file for including the function prototypes in bootloader code

When adding more heap memory, the total heap size was not updated. This
results in a crash in mm_mallinfo:
DEBUGASSERT((size_t)info->uordblks + info->fordblks == heap->mm_heapsize);
This commit fixes this issue
Summary:
- This commit adjusts TCP and UDP configurations based on
sabre-6quad/configs/netnsh/defconfig
Impact:
- sabre-6quad only
Testing:
- Tested with QEMU-7.1

Cast substraction arguments to FAR char *, which gives the same result as the
gcc extension on the original void * arithmetic.

SHM area is just mapped memory, the physical backup is not owned by the
process, so the process must not free it.
In ARM this is already handled as the regions are destroyed one by one,
while this implementation does a page directory walk instead.
the application can access the remote cpu touch driver by
rpmsgdev, so the defines and struct will be used even if not
enable the CONFIG_INPUT/CONFIG_INPUT_TOUCHSCREEN.

A testcase as following:
child_task()
{
sleep(3);
}
main_task()
{
while (1)
{
ret = task_create("child_task", child_task, );
sleep(1);
task_delete(ret);
}
}
Root casuse:
task_delete hasn's cover the condition that the deleted-task
is justing running on the other CPU.
Fix:
Let the nxsched_remove_readytorun() do the real work

1. When pthread exit, set the default cancellability state to NONCANCELABLE state.
2. Make sure modify tcb->flags is atomic operations.

Same as with group_free(), there is no need to instantiate the address
environment to destroy it.
The only problem was the ARM implementation modified the L1 mappings
in up_addrenv_destroy(), which it no longer does.
This is unnecessary, the address environment is getting wiped anyway,
there is no need to remove the L1 references because they will get
wiped when the page directory is changed
This is just unnecessary, a process cannot be destroyed by another
process in any case, every time this is executed the active address
environment is the process getting destroyed.
Even in the hypothetical case this was possible, the system would
crash at once if a context switch happens between "select()" and
"restore()", which is possible as the granule allocator is protected by
a semaphore (which is a synchronization point).
