e816ac7124 isr_tables: Support hardware interrupt vector table-only configuration.
The existing isr_tables implementation does not allow enabling only
hardware interrupt vector table without software isr table.

This commit ensures that CONFIG_GEN_IRQ_VECTOR_TABLE can be used
without setting CONFIG_GEN_SW_ISR_TABLE.

8ccc04de6a tracing: add infrastructure for collection of tracing data
First, this commit adds user interface in tracing_format.h which
can trace both string format and data format packet.

Second, it adds method both for asynchronous and synchronous way.
For asynchronous method, tracing packet will be buffered in tracing
buffer first, tracing thread will output the stream data with the
help of tracing backend when tracing thread get scheduled.

Third, it adds UART and USB tracing backend for asynchronous
tracing method, and adds POSIX tracing backend for synchronous
tracing way.

Also it can receive command from host to dynamically enable and
disable tracing to have host capture tracing data conveniently.

51bc0a065c linker: Make alignment size for sw_isr_table configurable
sw_isr_table has two entries, an argument and an ISR function.  The
comment on struct _isr_table_entry in include/sw_isr_table.h says that
"This allows a table entry to be loaded [...] with one ldmia
instruction, on ARM [...]".  Some arch, e.g. SPARC, also has a double
word load instruction, "ldd", but the instruct must have address align
to double word or 8 bytes.

This commit makes the table alignment configurable.  It allows each
architecture to specify it, if needed.  The default value is 0 for no
alignment.

5f19c8160a subsys/settings: Update bluetooth module
Updated the bluetooth module to use static handlers. Removed the
old bt specific static registration.

The routine bt_settings_init() is still calling settings_init() which
IMO is not needed anymore.

Updates:

changed SETTINGS_REGISTER_STATIC() to SETTINGS_STATIC_HANDLER_DEFINE()
changed settings_handler_stat type to settings_handler_static type
removed NULL declarations
renamed bt_handler to bt_settingshandler, as bt_handler already exists.
renamed all bt_XXX_handler to bt_xxx_settingshandler to avoid any
overlap.
changed SETTINGS_STATIC_HANDLER_DEFINE() to create variable names from
_hname by just prepending them with settings_handler_.
updated all bt_xxx_settings_handler to just bt_xxx.

c20ff1150f subsys/settings: Enable handler ROM registration
Add the possibility to register handles to ROM using a new macro
SETTINGS_REGISTER_STATIC(handler), the handler is of type
settings_handler_stat and has to be declared as const:

```
const struct settings_handler_stat test_handler = {
	.name = "test", /* this can also be "ps/data"
	.h_get = get,
	.h_set = set,
	.h_commit = NULL, /* NULL defines can be ommited */
	.h_export = NULL  /* NULL defines can be ommited */
};
SETTINGS_REGISTER_STATIC(test_handler);
```

To maintain support for handlers stored in RAM (dynamic handlers)
`CONFIG_SETTINGS_DYNAMIC_HANDLERS`must be enabled, which is by default.

When registering static handlers there is no check if this handler has
been registered earlier, the latest registered static handler will be
considered valid for any set/get routine, while the commit and export
routines will be executed for both registered handlers.

When a dynamic handler is registered a check is done to see if there was
an earlier registration of the name as a static or dynamic handler
registration will fail.

To get to the lowest possible RAM usage it is advised to set
`CONFIG_SETTINGS_DYNAMIC_HANDLERS=n`.

Updates:

a. Changed usage of RAM to DYNAMIC/dynamic, ROM to STATIC/static
b. Updated settings.h to remove added #if defined()
c. Make static handlers always enabled
d. Corrected error introduced in common-rom.ld.
e. Changed return value of settings_parse_and_lookup to
   settings_handler_stat type to reduce stack usage.
f. Updated the name generated to store a handler item in ROM. It now
   uses the name used to register in combination with the line where
   SETTINGS_REGISTER_STATIC() is called.
g. renamed settings_handler_stat type to settings_handler_static
h. renamed SETTINGS_REGISTER_STATIC to SETTINGS_STATIC_HANDLER_DEFINE()

b1d3742ce2 linker generated list: introduce Z_STRUCT_SECTION_ITERABLE()
This convenience macro wraps Z_DECL_ALIGN() and __in_section() to
simplify static definitions of structure instances gathered in dedicated
sections. Most of the time those go together, and the section name is
already closely related to the struct type, so abstracting things behind
a simpler interface reduces probability of mistakes and makes the code
clearer. A few input section names have been adjusted accordingly.

e0f3ab6bf2 Bluetooth: GATT: Add support for static services
This reintroduces support for static service in the form of a new API,
BT_GATT_SERVICE_DEFINE, and changes the internal services (GAP/GATT)

71e90f98fd Gcov: Enable Code coverage reporting over UART.
This patch provides support for generating Code coverage reports.
The prj.conf needs to enable CONFIG_COVERAGE. Once enabled, the
code coverage data dump now comes via UART.
This data dump on the UART is triggered once the main
thread exits.

Next step is to save this data dump on file. Then run
scripts/gen_gcov_files.py with the serial console log as argument.

The last step would be be to run the gcovr. Use the following cmd
 gcovr -r . --html -o gcov_report/coverage.html --html-details

Currently supported architectures are ARM and x86.

Add monochrome character framebuffer for monochrome
graphic dot matrix displays and electrophoretic displays.

These displays are mostly monochrome and can only display
black and some other color, for example white. Typically,
a byte controls 8 pixels, arranged vertically or horizontally
depending on the controller or settings.
The API is not suitable to display graphics, the purpose is
to display text or symbols. It is possible to use several fonts.
A font can also consist of graphic symbols only and thus,
for example, enable the realization of a menu.

877f82e847 userspace: add K_THREAD_ACCCESS_GRANT()
It's possible to declare static threads that start up as K_USER,
but these threads can't do much since they start with permissions on
no kernel objects other than their own thread object.

Rather than do some run-time synchronization to have some other thread
grant the necessary permissions, we introduce macros
to conveniently assign object permissions to these threads when they
are brought up at boot by the kernel. The tables generated here
are constant and live in ROM when possible.

Example usage:

K_THREAD_DEFINE(my_thread, STACK_SIZE, my_thread_entry,
                NULL, NULL, NULL, 0, K_USER, K_NO_WAIT);

K_THREAD_ACCESS_GRANT(my_thread, &my_sem, &my_mutex, &my_pipe);

get rid of a linker-epilog.h that wasn't necessary and whose purpose
has been lost to the mists of time. If applications want to define their
own sections they should be allowed to. Linker scripts for x86 do not
end with .h any more, they are not C header files even though we use
C's preprocessor.
