ff872dc349 build: rename non-generated linker scripts to .ld extension
Avoids confusion with .gitignore rules, which were inadequate to
cover all the places where these files are found. At least in
VIM, these files are now syntax highlighted correctly.

fea1c49ba2 gpio: Improve the public API to handle multi callbacks
Many sub-systems might require to set a callback on different pins.
Thus enabling it via changing the API.

It is also possible to retrieve private-data in the callback handler
using CONTAINER_OF() macro (include/misc/util.h).

Former API is still available, and is emulated through the new one.
Using both should not be a problem as it's using new API calls.
However, it's now better to start using the new API.

21628d41d0 arm: add support for linking images entirely in SRAM
The image will be linked at a different address and with different
ROM/RAM sizes to allow running a bootloder image that loads a payload
image. The addresses/sizes depend on if it is a XIP image or not
(CONFIG_XIP), and in the case of a XIP image, if it is a bootloader
image (CONFIG_IS_BOOTLOADER) or not.

In the case of a bootloader, it is given the full ROM and
CONFIG_BOOTLOADER_SRAM_SIZE kB of SRAM.  When not a XIP image, it is given
the full SRAM minus CONFIG_BOOTLOADER_SRAM_SIZE kB, and is linked at the
start of SRAM.

2a1ae3f436 ARM: ARC: put sw_isr_table in ROM by default
We can save a great deal of RAM this way, it only needs to be
in RAM if dynamic interrupts are in use.

At some point this config option broke, probably when static
interrupts were introduced into the system.

To induce build (instead of runtime) errors when irq_connect_dynamic()
is used without putting the table in RAM, the dynamic interrupt
functions are now conditionally compiled.

02a6baee12 linker: move check for bad initlevels to the end of the sections
This way, it does not fall in the middle of a group, like the RAM group
and as a side-effect potentially move the dot (current address pointer).

fb6de2d486 init: Add protection against incorrect levels or priorities
Initialization level can be one of five predefined.
Init priority is numeric from 1 to 99. If init level or priority
is defined wrong, linker prints out the message and stops.

9fce2a2209 Remove obsolete ctors section
Remove prototype support for C++ constructors, since it is not well
designed. Device drivers (or other application code) that requires an
automatic initialization capability should use the device initialization
macros instead.

Note: Support for C++ constructors may be re-introduced at a later date.
However, a number of issues need to be settled, such as when the
constructors are invoked and what context they run in. (Running them
during nanokernel initialization, as was previously done, is probably
not the right approach.)

09303f7f68 linker scripts: add symbols for ROM/RAM boundaries
These symbols have more meaningful names when trying to figure out where
the ROM/RAM starts/ends, rather than relying on e.g. __data_rom_start for
the end of the ROM (__data_rom_start is the beginning of the data in
ROM, thus is not part of the image).

851c6f8f60 microkernel: introduce private event objects
This patch enables defining microkernel events within source code.
This is similar to other private kernel object patches.

The test has been modified a little bit due to the fact that
the event ID is now a memory address, instead of numeric ID.

a860cb7bff init: Support fine-grained device initialization priorities
Introduces the SYS_DEFINE_DEVICE() macro, which supports 5 distinct
levels of device initialization and 100 priorities within each level.

Note: The existing init macros (e.g. nano_early_init()) have been
adapted to utilize the enhanced initialization model, but will
eventually be retired.

8253b90cfc microkernel: add task pointer list
Due to similar padding issue as pipe, the list of task object
may not be used directly. As mentioned before, some compiler/linker
may pad the large struct. For example, compiling under gcc and
march=i686 pads the struct to 32-byte alignment (march=atom to
64-byte alignment). This causes issue with sizeof() and pointer
arithmetic because they have no idea about the padding.
When the stars align in a certain way, these task structs may be
corrupted. So add a task pointer list and use it for task
manipulation. The task list remains as it is beneficial to group
them together to take advantage of cache locality.
