For the old codes, if nest interrupts come out after _isr_wrapper
and before _check_nest_int_by_irq_act, then multi-bits in irq_act
will be set, this will result irq stack will not be switched in
correctly
As a fix, it's still need to use nest interrupt counter to do
interrupt stack switch as before
The difference is in the past exc_nest_count is used, but here
_kernel.nested/_kernel.cpus[cpu_id].nested is used.

* in arc secureshield interrupts can be configured
as secure or normal
* in sw design, high interrupt priorites are allocated to
secure world, low priorities are allocated to normal world.
* secure interrupt > secure thread > normal interrupt > normal

So, here secure world/firmware only checks secure interrupt
priorities

This commit adds basic userspace support to the logging subsystem.
With this change, the following API could be called from user mode:
- LOG_*()
- LOG_INST_*(),
- LOG_HEXDUMP_*(),
- LOG_HEXDUMP_INST_*(),
- LOG_PANIC(), LOG_PROCESS(),
- log_printk(), log_generic(), log_buffrered_cnt(),
- log_filter_set(NULL, ...)
With userspace disabled, the logger behavior and performance
is not affected. With userspace enabled, the calls from kernel
space have an additional overhead introduced by _is_user_context().
The logger behavior changes when it is called from the user context.
All strings logged using LOG_*() and LOG_INST_*() API from userspace
are rendered in place for security reasons and then placed in
log_strdup() memory pool, which should be large enough to hold bursts
of log messages.

Remove bunch of TC_PRINT's with too verbose logging of test operations.

A security vulnerability in the Bluetooth BR/EDR Bluetooth Core
specification versions 1.0 through 5.1 has been identified as
CVE-2019-9506. The Bluetooth BR/EDR encryption key negotiation
protocol is vulnerable to packet injection that could allow an
unauthenticated user to decrease the size of the entropy of the
encryption key, potentially causing information disclosure and/or
escalation of privileges via adjacent access. There is not currently
any knowledge of this being exploited.
From Core spec erratum 11838:
A device shall enforce an encryption key with at least 128-bit
equivalent strength for all services that require Security Mode 4,
Level 4. For all other services that require encryption, a device
should enforce an encryption key with at least 56-bit equivalent
strength, irrespective of whether the remote device supports Secure
Simple Pairing.
After encryption has been enabled, the Host should check the
encryption key size using either the HCI_Read_Encryption_Key_Size
command (see [Vol 2] Part E, Section 7.5.7) or a vendor-specific
method.

The storage for the public key is pub_key in hci_core.c.
When the public key event is generated the public key is copied into
this buffer, but the pointer to the event storage of the key is given
in the public key ready callback (bt_smp_pkey_ready).
SMP expects that it is safe to assign a global pointer to this variable.
In smp_init bt_pub_key_get is used to get the pointer to the public key.
In both cases SMP assigns the le_sc_pub_key to the pointer given.
This creates an issue when bt_smp_pkey_ready callback occurs after
smp_init during pairing procedure, SMP will then have a pointer to an
event buffer that has been released and contains invalid data.
