Provide unit in config.xml and documentation

This commit remove urn:AGL:widget:provided-application
in favour of urn:AGL:widget:provided-unit.
In the same time, the feature urn:AGL:widget:provided-api
must be attached to a unit. This will enable to export
more than one API for a unit if needed.

-----------------------

-It contains rules for launching applications.
-When **afm-user-daemon** has to launch an application,
-it looks for launch mode (local or remote), as well as
-for the type of application describe in ***config.xml***
-widget configuration file.
-
-This tuple mode+type allows to select the adequate rule.
-
-Configuration file is **/etc/afm/afm-launch.conf**.
-
-It contains sections and rules. It can also contain comments
-and empty lines to improve readability.
-
-The separators are space and tabulation, any other character
-should have a meaning.
-
-The format is line oriented.
-The new line character separate the lines.
-
-Lines having only separators are blank lines and ignored.
-Line having character #(sharp) at first position are comment
-lines and ignored.
-
-Lines not starting with a separator are different
-from lines starting with a separator character.
-
-The grammar of the configuration file is defined below:
-
-    CONF: *COMMENT *SECTION

-
-    mode local

-        /usr/bin/web-runtime http://localhost:%P/%c?token=%S
-
-This shows that:
-
- - within a section, several rules can be defined
- - within a rule, several types can be defined
- - within a rule, one or two vectors can be defined
- - vectors are using %substitution
- - launched binaries must be defined with their full path
-
-### mode local
-
-Within this mode, the launchers have either one or two description vectors.
-All of those vectors are treated as programs
-and are executed with 'execve' system call.
-
-The first vector is the leader vector and it defines the process
-group. The second vector (if any) is attached to the group
-defined by this first vector.
-
-### mode remote
-
-Within this mode, the launchers have either one or two vectors
-describing them.
-
-The first vector is process as a program and is executed with
-system call 'execve'.
-
-The second vector (if any) defines a text that is returned
-to the caller. This mechanism can be used to return a uri
-for remote UI to connect on the newly launched application.
-
-The daemon ***afm-user-daemon*** allocates a port for each
-new remote application.
-The current implementation port allocation is incremental.
-A smarter (cacheable and discoverable) allocation should be defined.
-
-### %substitutions
-
-Vectors can include sequences of 2 characters that have a special
-meaning. These sequences are named *%substitution* because their
-first character is the percent sign (%) and because each occurrence
-of the sequence is replaced, at launch time, by the value associated
-to sequences.
-
-Here is the list of *%substitutions*:
-
- - ***%%***: %.
-
-   This simply emits the percent sign %
-
- - ***%a***: appid
-
-   Holds application Id of launched application.
-
-   Defined by the attribute **id** of the element **<widget>**
-   of **config.xml**.
-
- - ***%b***: bindings
-
-   In the future should represent the list of bindings and bindings directory separated by ','.
-   Warning: not supported in current version.
-
- - ***%c***: content
-
-   The file within the widget directory that is the entry point.
-
-   For HTML applications, it represents the relative path to main
-   page (aka index.html).
-
-   Defined by attribute **src** of the element **<content>** within **config.xml**.
-
- - ***%D***: datadir
-
-   Path of the directory where the application runs (cwd)
-   and stores its data.
-
-   It is equal to %h/%a.
-
- - ***%H***: height
-
-   Requested height for the widget.
-
-   Defined by the attribute **height** of the element **<widget>**
-   of **config.xml**.
-
- - ***%h***: homedir
-
-   Path of the home directory for all applications.
-
-   It is generally equal to $HOME/app-data
-
- - ***%I***: icondir
-
-   Path of the directory were the icons of the applications can be found.
-
- - ***%m***: mime-type
-
-   Mime type of the launched application.
-
-   Defined by the attribute **type** of the element **<content>**
-   of **config.xml**.
-
- - ***%n***: name
-
-   Name of the application as defined by the content of the
-   element **<name>** of **config.xml**.
-
- - ***%P***: port
-
-   A port to use. It is currently a kind of random port. The precise
-   model is to be defined later.
-
- - ***%R***: readyfd
-
-   Number of file descriptor to use for signaling
-   readiness of launched process.
-
- - ***%r***: rootdir
-
-   Path of directory containing the widget and its data.
-
- - ***%S***: secret
-
-   An hexadecimal number that can be used to initialize pairing of client
-   and application binder.

+The specification of [widgets][widgets] is intentded to describe
+only one application. In the present case, we expect to describe
+more than just an application. For example, a publisher could
+provide a widget containing a service, an application for tuning
+that service, an application that leverage the service.
+Here, the term of service means a background application that
+runs without IHM and whose public api can be accessed by other
+applications.
+
+So the features are used to describe each of the possible
+units of widgets. The "standard" unit in the
+meaning of [widgets][widgets] is called the "main" unit.

+
+The configuration file afm-unit.conf
+====================================
+
+The integration of the framework with systemd
+mainly consists of creating the systemd unit
+files corresponding to the need and requirements
+of the installed widgets.
+
+This configuration file named `afm-unit.conf` installed
+on the system wiht the path `/etc/afm/afm-unit.conf`
+describes how to generate all units from the *config.xml*
+configuration files of widgets. The description uses an extended
+version of the templating formalism of [mustache][]
+to describes all the units.
+
+Let present how it works using the following diagram that
+describes graphically the workflow of creating the unit
+files for systemd `afm-unit.conf` from the configuration
+file of the widget `config.xml`:
+
+![make-units][make-units]
+
+In a first step, and because [mustache][] is intended
+to work on JSON representations, the configuration file is
+translated to an internal JSON representation. This
+representation is shown along the examples of the documentation
+of the config files of widgets.
+
+In a second step, the mustache template `afm-unit.conf`
+is instanciated using the C library [mustach][] that follows
+the rules of [mustache][mustache] and with all its available
+extensions:
+
+ - use of colon (:) for explicit substitution
+ - test of values with = or =!
+
+In a third step, the result of instanciating `afm-unit.conf`
+for the widget is splited in units. To achieve that goal,
+the lines containing specific directives are searched.
+Any directive occupy one full line. The directives are:
+
+  - %nl
+
+    Produce an empty line at the end
+
+  - %begin systemd-unit
+  - %end systemd-unit
+
+    Delimit the produced unit, its begin and its end
+
+  - %systemd-unit user
+  - %systemd-unit system
+
+    Tells the kind of unit (user/system)
+
+  - %systemd-unit service NAME
+  - %systemd-unit socket NAME
+
+    Gives the name and type (service or socket) of the unit.
+    The extension is automatically computed from the type
+    and must not be set in the name.
+
+  - %systemd-unit wanted-by NAME
+
+    Tells to install a link to the unit in the wants of NAME
+
+Then the computed units are then written to the filesystem
+and inserted in systemd.
+
+The generated unit files will contain variables for internal
+use of the framework. These variables are starting with `X-AFM-`.
+The variables starting with `X-AFM-` but not with `X-AFM--` are
+the public variables. These variables will be returned by the
+framework as the details of an application (see **afm-util detail ...**).
 
----
+Variables starting with `X-AFM--` are private to the framework.
+By example, the variable  `X-AFM--http-port` is used to
+record the allocated port for applications.
