Each GCC target backend is at liberty to define its own SIZE_TYPE. GCC
uses this for various purposes, not lease it drives the machinery that
spits out format specifier diagnostics when format specifiers are
applied to objects with inappropriate type. GCC exposes the current
definition of SIZE_TYPE via the preprocessor symbol __SIZE_TYPE__.
The GCC build processes also generates various standard library header
files that directyle expose stanard types in a form consistent with
the current configuration of GCC. Conventionally standard library
build processes (for glibc and newlib) pick up the header files
generated by the GCC build.
In the minimal libc we have no such build process, we don't pick up
the header files that the GCC build process generated. Instead we
define our own alternative header files and align them with GCC
manually.
The current definition of ssize_t in minimal libc is out of step with
GCC which means that any use of the %z[du] format modifier will issue
a diagnostic.
We replace the open coded architecture detection in minimal libc and
use GCCs __SIZE_TYPE__ directly.

In order to keep the initialization process light-weight, remove
net_buf_pool_init() and instead perform the initialization of the pool
and buffers in a "lazy" manner. This means storing more information
in the pool, and removing any 'const' members from net_buf. Since
there are no more const members in net_buf the buffer array can be
declared with __noinit, which further reduces initialization overhead.

Until now it has been necessary to separately define a k_fifo and
an array of buffers when creating net_buf pools. This has been a bit
of an inconvenience as well as blurred the line of what exactly
constitutes the "pool".
This patch removes the NET_BUF_POOL() macro and replaces it with a
NET_BUF_POOL_DEFINE() macro that internally expands into the buffer
array and new net_buf_pool struct with a given name:
NET_BUF_POOL_DEFINE(pool_name, ...);
Having a dedicated context struct for the pool has the added benefit
that we can start moving there net_buf members that have the same
value for all buffers from the same pool. The first such member that
gets moved is the destroy callback, thus shrinking net_buf by four
bytes. Another potential candidate is the user_data_size, however
right not that's left out since it would just leave 2 bytes of padding
in net_buf (i.e. not influence its size). Another common value is
buf->size, however that one is also used by net_buf_simple and can
therefore not be moved.
This patch also splits getting buffers from a FIFO and allocating a
new buffer from a pool into two separate APIs: net_buf_get and
net_buf_alloc, thus simplifying the APIs and their usage. There is no
separate 'reserve_head' parameter anymore when allocating, rather the
user is expected to call net_buf_reserve() afterwards if something
else than 0 headroom is desired.

This commit adds HTTP message handling support for Zephyr.
So, no network routines are involved at this level.
To add HTTP message handling support for Zephyr, we explored the
following options:
1. Importing an external project and perhaps adapting it to fit our
requirements.
The criteria to pick one codebase among all the available projects
are: licensing, correctness and performance.
2. Writing our own implementation from scratch.
We decided to import an external project instead of implementing our
own parser, mainly due to code maturity and correctness. It could take
more time to obtain a production-ready parser from scratch than adapting
a state-of-art library.
The following is a list of some projects offering similar functionality.
lighttpd (many files)
* License: revised BSD license
* Supported: active
* Comments: this parser can't be integrated to Zephyr due to
dependencies that currently are not satisficed by our SDK.
nginx (src/http/ngx_http_parse.c)
* License: 2-clause BSD-like
* Supported: very active
* Comments: this parser can't be integrated to Zephyr due to
dependencies that currently are not satisficed by our SDK.
wget (src/http-parse.c)
* License: GPL 3.0
* Supported: very active
* Comments: this code can't be included in Zephyr due to
licensing issues
curl (lib/http.c)
* License: MIT/X derivate, see:
https://curl.haxx.se/docs/copyright.html
* Supported: very active
* Comment: it must be forked and adapted to run in Zephyr.
It is not optimized for low-power devices.
nodejs http-parser (http_parser.c)
* License: nginx license (2-clause BSD-like) and MIT license
* Supported: very active
* Comments: optimized with performance in mind.
From https://github.com/nodejs/http-parser: "It does
not make any syscalls nor allocations, it does not buffer data,
it can be interrupted at anytime. It only requires about 40
bytes of data per message stream."
So, nodejs/http-parser looks a very good choice for Zephyr. In this
commit, we integrate nodejs' parser to Zephyr.

The RFC defines an '.well-known/core' resource that will list the

The implementation uses the fact that resources are organized in an
array: only the resources present in the array after the
"ZOAP_WELL_KNOWN_CORE_RESOURCE" will be considered, this allows a
primitive form of visibility control for the attributes.

If newlib is configured with --enable-newlib-nano-formatted-io,
floating-point support is split out of the formatted I/O code into
weak functions which are not linked by default. This leads to a smaller
code by about 16~20k when using newlib "printf" and/or "sscanf" but not
using floating point I/O.
Programs that need floating-point I/O support must explicitly request
linking of one or both of the floating-point functions:
_printf_float or _scanf_float.
This can be done at link time using the -u option which can be passed
to either gcc or ld.

The _to_float() implementation had a somewhat kludgey hand-written 64
bit math implementation, which is unhelpful on Zephyr as all our
toolchains provide a working uint64_t runtime. This is at best just
dupicated code from libgcc, and at worst less efficient.
This patch replaces the existing 64 bit minilibrary but keeps the
uint32_t[2] API as is for ease of validation and review.
One exception is _ldiv5, a specialized divide-by-five implementation.
The 64 bit division routines are large on some architectures (ARM and
ARC in particular), not pulled in by a default Zephyr build, and will
swamp the benefit from this patch. So this includes a
refactored/improved _ldiv5 which leverages libgcc for multiword shifts
instead of just using raw division.
Note also the "noinline" attribute on _ladd(). This is a workaround
for an apparent compiler bug when built with -Og or -Os (hand-hacking
the Makefiles to build with -O0 works), perhaps due to my aliasing the
int array with a long long. This will go away in phase 2.

The _to_float routine was apparently written to be able to take a 32
bit float bit representationa as well as a 64 bit double. But in a
printf routine, that can never happen per the C standard (where floats
are always promoted to doubles in varargs context).
This was just hard-configured to 1 at the top of the file, and nothing
else in the project sets "DOUBLE" to try to change it. Just remove
it. If we ever want code to convert a float to a double in memory so
we can use this routine, we have it in libgcc. Or even in hardware on
the FPU where available.

Hex, octal and decimal all had separately implemented reduction loops
to generate strings. With only a little work these can all be unified
to a single implementation that works with an arbitrary base.
Performance is probably a little lower owing to the fact that
hex/octal now requires a division per character, and the extra
"reverse the string" trick at the end of the conversion. But code
size savings are substantial.

Instead of building a hierarchy of objects linked into the

linked against the microkernel binary.
The location of the libc is configurable with the variable
KLIBC_DIR. This gives the flexibility to build against a
different libc other than minimal.
