Shell log backend was using k_fifo to enqueue log messages.
It was using field in log message that was used for same
purpose in log_core before passing message to backends.
However, this method supported only single shell as
other shell was corruption the fifo because field was
reused.
Modified shell log backend to use k_msgq for pending
messages.

Currently shell UART backend is interrupt driven if UART driver
is interrupt driven. That can be limitation if one instance
wants to use interrupts but shell UART should not.
Added option to shell uart to be able to control use of
interrupts. By default interrupts are enabled if driver
supports it.

Application may need to handle the write differently depending on the
write operation so this adds a flag called BT_GATT_WRITE_FLAG_CMD which
can then be checked by the callback, for instance one can respond with
BT_ATT_ERR_WRITE_REQ_REJECTED when that flag is not set which should
indicate to the client to use write command instead.

Add new, socket based MQTT implementation, based on MQTT from Nordic
nRF5 SDK, introducing the following features:
* transport independent MQTT logic, with support for multiple transports
* support for multiple MQTT versions (3.1.0 and 3.1.1 supported)
* single event handler - no need to keep callback array in RAM
* automatic send of Ping Requests, for connection keep-alive
* message/event parameters wrapped into strucutres - easier extension
for future MQTT versions
* no separate thread needed to run MQTT - application only needs to call
mqtt_input and mqtt_live periodically

The type of Z_EXC_HANDLE was incorrectly declared, this was causing
the compiler to make incorrect inferences about what could be in
exc_handle and caused a bug in fault.c.
To get more specific ...
An exception handler consists of three void pointers, or function
pointers. The function pointers point to functions. An example of one
such function is 'z_arch_user_string_nlen_fault_start' From
userspace.S.
The correct way of initalizing a function pointer from a function
declared in another source file looks like this:
void external_defined_function(void);
{
void * internal_initialized_function_ptr = external_defined_function;
}
But EXC_HANDLER is not doing this. Instead it does this:
extern void (*external_defined_function)(void);
{
void * internal_initialized_function_ptr = &external_defined_function;
}
The declaration here is wrong. It declares that externally, there is
stored a function pointer somewhere. Which is not true. There does not
exist a function pointer anywhere. But this doesn't matter, because we
don't actually de-reference the function pointer to find the address
of the function, but instead we take the address of the function
pointer.
Taking the address of the function pointer to find the address of a
function is wrong, one should de-reference function pointers to find
function addresses. Luckily, these two bugs have been cancelling each
other out, until recently.
This patch corrects the type used.

These changes were obtained by running a script created by
Ulf Magnusson <Ulf.Magnusson@nordicsemi.no> for the following
specification:
1. Read the contents of all dts_fixup.h files in Zephyr
2. Check the left-hand side of the #define macros (i.e. the X in
#define X Y)
3. Check if that name is also the name of a Kconfig option
3.a If it is, then do nothing
3.b If it is not, then replace CONFIG_ with DT_ or add DT_ if it
has neither of these two prefixes
4. Replace the use of the changed #define in the code itself
(.c, .h, .ld)
Additionally, some tweaks had to be added to this script to catch some
of the macros used in the code in a parameterized form, e.g.:
- CONFIG_GPIO_STM32_GPIO##__SUFFIX##_BASE_ADDRESS
- CONFIG_UART_##idx##_TX_PIN
- I2C_SBCON_##_num##_BASE_ADDR
and to prevent adding DT_ prefix to the following symbols:
- FLASH_START
- FLASH_SIZE
- SRAM_START
- SRAM_SIZE
- _ROM_ADDR
- _ROM_SIZE
- _RAM_ADDR
- _RAM_SIZE
which are surprisingly also defined in some dts_fixup.h files.
Finally, some manual corrections had to be done as well:
- name##_IRQ -> DT_##name##_IRQ in uart_stm32.c

Nios2 is trying to use global pointer register to access variables
smaller than 8 bytes. GPR range is limited to 64 bytes and apparently
does not handle well variables placed in custom sections.
Current workaround is to increase logger structures (const and dynamic)
size (+8 bytes for dynamic, +4 bytes for constant). Then GPR is not
used and application can be linked. The downside is increase of memory
usage:
- ROM: <num_of_log_modules>*4 bytes
- RAM: <num_of_log_modules>*8 bytes (if runtime filtering is enabled)

If dynamic interrupts are enabled, a set of trampoline stubs
are generated which transfer control to a common dynamic
interrupt handler function, which then looks up the proper
handler and parameter and then executes the interrupt.
Based on the prior x86 dynamic interrupt implementation which
was removed from the kernel some time ago, and adapted to
changes in the common interrupt handling code, build system,
and IDT generation tools.
An alternative approach could be to read the currently executing
vector out of the APIC, but this is a much slower operation.

This commit contributes a patch to the Arm Cortex-M linker
script, which guarantees that the linker sections for shared
memory and the application memory will have sufficient padding
in between, so that the latter will start from an address that
is 32-byte aligned. This is required for ensuring that the MPU
regions defined using the start and end addresses of the two
sections will not overlap. The patch targets ARMv8-M MPU with
no requirement for power-of-two alignment and size.
