Moved all libc Kconfigs to where the code is and remove the default
Kconfig for selecting the minimal libc. Minimal libc is now the default
if nothing else is configured in.
Removed the options for extended libc, this obviously was restricting
features in the minimal libc without a good reason, most of the
functions are available directly when using newlib, so there is no
reason why we need to restrict those in minimal libc.

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.

This patch reformats the http_parser files to reduce checkpatch
warnings. Changes made in this refactoring are available at:
