Chris Friedt 79d4107beb net: http: define http service and resource iterable sections
Provide a means of declaring zero or more HTTP services, each
with zero or more static HTTP resources.

Static HTTP resources are those which have fixed paths[1] which
are known prior to system initialization. Some examples of
static http resources would be

* a forwarder from '/' to '/index.html'
* a REST endpoint with fixed path '/api/foo' and detail
  pointing at some implementation-specific function
* a Javascript file in string form with fixed path '/js/util.js'
* a 'construction' image with path '/res/work.png'
* a gzip-compressed 'Hello' HTML file at '/hello.html'

Without describing in any detail how static HTTP resources are
organized or served by any given HTTP server, we can describe
what static resources exist on a system in a common way that
does not require any optional facilities (e.g. filesystem) and
relies only on addressable memory.

Additionally, for the purposes of simply allowing others
to implement custom HTTP servers in a consistent way, or
benchmarking implementations, or having a consistent testsuite
to use across multiple implementations, it is helpful to have
a common method to declare HTTP services and static resources
for Zephyr.

Torsten Rasmussen 36f5600387 kconfig: net: experimental settings now uses select EXPERIMENTAL
With the introduction of `EXPERIMENTAL` and `WARN_EXPERIMENTAL` in
Zephyr all subsys/net and drivers/ethernet/Kconfig.e1000 settings
having `[EXPERIMENTAL]` in their prompt has has been updated to include
`select EXPERIMENTAL` so that developers can enable warnings when
experimental features are enabled.

The following settings has EXPERIMENTAL removed as they are considered
mature:
- NET_OFFLOAD
- NET_PROMISCUOUS_MODE

Ulf Magnusson bd6e04411e kconfig: Clean up header comments and make them consistent
Use this short header style in all Kconfig files:

    # <description>

    # <copyright>
    # <license>

    ...

Also change all <description>s from

    # Kconfig[.extension] - Foo-related options

to just

    # Foo-related options

It's clear enough that it's about Kconfig.

The <description> cleanup was done with this command, along with some
manual cleanup (big letter at the start, etc.)

    git ls-files '*Kconfig*' | \
        xargs sed -i -E '1 s/#\s*Kconfig[\w.-]*\s*-\s*/# /'

Ulf Magnusson ec3eff57e0 Kconfig: Use the first default with a satisfied condition
Up until now, Zephyr has patched Kconfig to use the last 'default' with
a satisfied condition, instead of the first one. I'm not sure why the
patch was added (it predates Kconfiglib), but I suspect it's related to
Kconfig.defconfig files.

There are at least three problems with the patch:

  1. It's inconsistent with how Kconfig works in other projects, which
     might confuse newcomers.

  2. Due to oversights, earlier 'range' properties are still preferred,
     as well as earlier 'default' properties on choices.

     In addition to being inconsistent, this makes it impossible to
     override 'range' properties and choice 'default' properties if the
     base definition of the symbol/choice already has 'range'/'default'
     properties.

     I've seen errors caused by the inconsistency, and I suspect there
     are more.

  3. A fork of Kconfiglib that adds the patch needs to be maintained.

Get rid of the patch and go back to standard Kconfig behavior, as
follows:

  1. Include the Kconfig.defconfig files first instead of last in
     Kconfig.zephyr.

  2. Include boards/Kconfig and arch/<arch>/Kconfig first instead of
     last in arch/Kconfig.

  3. Include arch/<arch>/soc/*/Kconfig first instead of last in
     arch/<arch>/Kconfig.

  4. Swap a few other 'source's to preserve behavior for some scattered
     symbols with multiple definitions.

     Swap 'source's in some no-op cases too, where it might match the
     intent.

  5. Reverse the defaults on symbol definitions that have more than one
     default.

     Skip defaults that are mutually exclusive, e.g. where each default
     has an 'if <some board>' condition. They are already safe.

  6. Remove the prefer-later-defaults patch from Kconfiglib.

Testing was done with a Python script that lists all Kconfig
symbols/choices with multiple defaults, along with a whitelist of fixed
symbols. The script also verifies that there are no "unreachable"
defaults hidden by defaults without conditions

As an additional test, zephyr/.config was generated before and after the
change for several samples and checked to be identical (after sorting).

This commit includes some default-related cleanups as well:

  - Simplify some symbol definitions, e.g. where a default has 'if FOO'
    when the symbol already has 'depends on FOO'.

  - Remove some redundant 'default ""' for string symbols. This is the
    implicit default.

Piggyback fixes for swapped ranges on BT_L2CAP_RX_MTU and
BT_L2CAP_TX_MTU (caused by confusing inconsistency).

Piggyback some fixes for style nits too, e.g. unindented help texts.

Ulf Magnusson 1073882998 subsys: kconfig: Remove 'default n' properties and clean up a bit
Bool symbols implicitly default to 'n'.

A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though.

Remove some 'default ""' properties on string symbols too.

Also make definitions more consistent by converting some

  config FOO
  	<type>
  	prompt "foo"

definitions to a shorter form:

  config FOO
  	<type> "foo"

This shorthand works for int/hex/string symbols too, not just for bool
symbols.

Jukka Rissanen d70c7383de net: websocket: Initial support for server websocket
This commit creates a websocket library that can be used by
applications. The websocket library implements currently only
server role and it uses services provided by net-app API.
The library supports TLS if enabled in configuration file.

This also adds websocket calls to HTTP app server if websocket
connection is established.

With the introduction of CoAP and other protocols, URL parsing is
be needed when HTTP_PARSER is not.  Let's split out the existing
functionality of URL parsing into it's own CONFIG and let
HTTP_PARSER use it by automatically selecting HTTP_PARSER_URL when
HTTP_PARSER is enabled.

Michael Scott fe84d4f7dd net: http: allow HTTP_NETWORK_TIMEOUT to be configured
Currently, the HTTP_NETWORK_TIMEOUT setting is hard-coded as 20 seconds.
Not every application may want to wait that long, so let's change this
to a CONFIG option: CONFIG_HTTP_CLIENT_NETWORK_TIMEOUT

NOTE: This also removes HTTP_NETWORK_TIMEOUT from the public http.h
include file.  It was not being used externally to HTTP client sources.

Michael Scott 081246737c net/http: let HTTP_SERVER, HTTP_CLIENT and HTTP_PARSER select HTTP
Due to commit 8308b9bd2d ("net/http: Add the HTTP/1.1 API")
every user of CONFIG_HTTP_PARSER would need to add CONFIG_HTTP to
their .conf files.  Which is fine for intree samples/tests as they
have been adjusted, but the rest of world working on Zephyr apps
will need to make this changes as well.

Instead, we should have each of the following select HTTP instead of
depend on it, which will make future use of these configs and their
dependencies more intuitive:
HTTP_SERVER
HTTP_CLIENT
HTTP_PARSER

NOTE: As cleanup, this commit also removes the CONFIG_HTTP added to
samples and test .conf files.

Flavio Santes 8308b9bd2d net/http: Add the HTTP/1.1 API
This patch adds the HTTP/1.1 API for Zephyr. This API consists of client
and server context structures enabled via Kconfig variables.
HTTP parser support is enabled via the CONFIG_HTTP_PARSER configuration
variable.

Currently, this API only includes support for writing HTTP requests
(client mode) and HTTP responses (server mode). TLS support is not
considered in this iteration.

Supported HTTP methods:
	GET, HEAD, OPTIONS and POST.

Supported HTTP responses:
	400, 403 404. The http_response routine may be used to write
	any HTTP status code, for example 200 OK.

Also updated doc/porting/application.rst that had a dependency on

Manually updated subsys/logging/sys_log.c that had a malformed
