This is joint work with Kumar Gala (see signed-off-by).
Add helper macros which abstract the "true names" of each of the four
types of node identifier we intend to support (e.g. DT_ALIAS(),
DT_INST()).
These can be passed to a new DT_PROP() macro which can be used to read
the value of a devicetree property given a node identifier from one of
these four other macros, and the as-a-c-token name of the property.
Add other accessor macros and tests as well.
Add some convenience APIs for writing device drivers based on instance
numbers as well. Drivers can "#define DT_DRV_COMPAT driver_compatible"
at the top of the file, then utilize these DT_INST_* macros to access
various property defines.
For example, the uart_sifive driver can do:
#define DT_DRV_COMPAT sifive_uart0
Then use DT_INST macros like:
.port = DT_INST_REG_ADDR(0),
.sys_clk_freq = DT_INST_PROP(0, clock_frequency),
For convenience working with specific hardware, also add:
<devicetree/gpio.h>
<devicetree/adc.h>
<devicetree/spi.h>

This supports a new devicetree macro syntax coming. It's not really
worth mixing up the old and the new generation scripts into one file,
because:
- we aim to remove support for the old macros at some point, so it
will be cleaner to start fresh with a new script based on the old one
that only generates the new syntax
- it will avoid regressions to leave the existing code alone while
we're moving users to the new names
Keep the existing script by moving it to gen_legacy_defines.py and
changing a few comments and strings around. It's responsible for
generating:
- devicetree.conf: only needed by deprecated kconfigfunctions
- devicetree_legacy_unfixed.h: "old" devicetree_unfixed.h macros
Put a new gen_defines.py in its place. It generates:
- zephyr.dts
- devicetree_unfixed.h in the new syntax
Include devicetree_legacy_unfixed.h from devicetree.h so no DT users
are affected by this change.

This is like MACRO_MAP(), but it pastes the results together into a

TCP code needs to know whether the pkt is sent the first time
or is it a resent one. This information is used when deciding
if the pkt ref count needs to be increased or not. The packet
does not need to increase ref count when sent first time, as
the ref count is already 1 when the pkt is created. But for the
2nd time the packet is sent, we will need to increase the ref
count in order to avoid buffer leak.

The current design of the network-specific stack dumping APIs

The current AArch64 interrupt system relies on the multi-level
interrupt mechanism and the `irq_nextlevel` public interface to invoke
the Generic Interrupt Controller (GIC) driver functions.
Since the GIC driver has been refactored to provide a direct interface,
in order to resolve various implementation issues described in the GIC
driver refactoring commit, the architecture interrupt control functions
are updated to directly invoke the GIC driver functions.
This commit also adds support for the ARMv8 cores (e.g. Cortex-A53)
that allow interfacing to a custom external interrupt controller
(i.e. non-GIC) by mapping the architecture interrupt control functions
to the SoC layer interrupt control functions when
`ARM_CUSTOM_INTERRUPT_CONTROLLER` configuration is enabled.

The current Generic Interrupt Controller (GIC) driver makes use of the
multi-level interrupt mechanism and `irq_nextlevel` public interface.
This is a less-than-ideal implementation for the following reasons:
1. The GIC is often used as the main interrupt controller for the
Cortex-A and Cortex-R family SoCs and, in this case, it is not a 2nd
level interrupt controller; in fact, it is the root interrupt
controller and therefore should be treated as such.
2. The only reason for using `irq_nextlevel` here is to interface the
architecture implementation to the interrupt controller functions.
Since there is no nesting or multiple instances of an interrupt
controller involved, there is really no point in adding such an
abstraction.
3. 2nd level topology adds many unnecessary abstractions and results
in strange coding artefacts as well as performance penalty due to
additional branching.
This commit refactors the GIC driver interface as follows:
1. Remove the current GIC driver interface based on the multi-level
interrupt mechanism and the `irq_nextlevel` public interface.
2. Define the GIC driver interface in
`include/drivers/interrupt_controller/gic.h` and allow the arch
implementation to directly invoke this interface.
