Device drivers need to be treated like other kernel objects, with
thread-level permissions and validation of struct device pointers passed
in from userspace when making API calls.
However it's not sufficient to identify an object as a driver, we need
to know what subsystem it belongs to (if any) so that userspace cannot,
for example, make Ethernet driver API calls using a UART driver object.
Upon encountering a variable representing a device struct, we look at
the value of its driver_api member. If that corresponds to an instance
of a driver API struct belonging to a known subsystem, the proper
K_OBJ_DRIVER_* enumeration type will be associated with this device in
the generated gperf table.
If there is no API struct or it doesn't correspond to a known subsystem,
the device is omitted from the table; it's presumably used internally
by the kernel or is a singleton with specific APIs for it that do not
take a struct device parameter.
The list of kobjects and subsystems in the script is simplified since
the enumeration type name is strongly derived from the name of the data
structure.
A device object is marked as initialized after its init function has
been run at boot.

To define a system call, it's now sufficient to simply tag the inline
prototype with "__syscall" or "__syscall_inline" and include a special
generated header at the end of the header file.
The system call dispatch table and enumeration of system call IDs is now
automatically generated.

Some versions of make seem to more greedy about how they match
$(notdir %).inc vs $(notdir %).gz.inc. If we put the gz.inc rule first
that seems to deal with the issue.

This header could be maintained by hand since there are no inputs
and it only changes if the generating script is modified, but given
the choice to maintain 800-ish lines of extremely repetitive C
preprocessor code, or 100-ish lines of Python, the choice is pretty
clear.

This commit is useful if there is a need to generate a file
that can be included into the application at build time.
The file can also be compressed automatically when embedding it.
Files to be generated are listed in
generate_inc_file
generate_inc_gz_file
variables.
How to use this commit in your application:
1. Add this to your application Makefile
SRC = $(ZEPHYR_BASE)/<your-app-dir>/src
include $(ZEPHYR_BASE)/scripts/Makefile.gen
2. Add needed binary/other embedded files into src/Makefile
to "generate_inc_file" or "generate_inc_gz_file" variables:
# List of files that are used to generate a file that can be
# included into .c file.
generate_inc_file += \
echo-apps-cert.der \
echo-apps-key.der \
file.bin
generate_inc_gz_file += \
index.html
include $(ZEPHYR_BASE)/scripts/Makefile.gen
3. In the application, do something with the embedded file
static const unsigned char inc_file[] = {
#include "file.bin.inc"
};
static const unsigned char gz_inc_file[] = {
#include "index.html.gz.inc"
};
The generated files in ${SRC}/*.inc are automatically removed
when you do "make pristine"

Allow the script to take multiple -f (fixup) file options. We output
the fixup files in order that the -f options are passed. This will
allow us to have a common soc fixup and board fixup if we desire.

If there's any key in the alias which length is larger than other keys
in the node, the include file will be incorrect, there will be no tab
between the key and value.
We need to take into account the max length of alias keys.

- _arch_is_user_context() implemented
- _new_thread() will honor K_USER option if passed in
- System call triggering macros implemented
- _thread_entry_wrapper moved and now looks for the next function to
call in EDI
