gsettings: Document GSettings build system integration

Browse Source 
Add a new section to the main GSettings documentation which documents
the best practices for integrating GSettings into an autoconf/automake
build system using the GLIB_GSETTINGS macro.

Some of this material was adapted from the migrating-gconf.xml guide.

* ## Build system integration # {#gsettings-build-system}
*
* GSettings comes with autotools integration to simplify compiling and
* installing schemas. To add GSettings support to an application, add the
* following to your `configure.ac`:
* |[
* GLIB_GSETTINGS
* ]|
*
* In the appropriate `Makefile.am`, use the following snippet to compile and
* install the named schema:
* |[
* gsettings_SCHEMAS = org.foo.MyApp.gschema.xml
* EXTRA_DIST = $(gsettings_SCHEMAS)
*
* @GSETTINGS_RULES@
* ]|
*
* No changes are needed to the build system to mark a schema XML file for
* translation. Assuming it sets the `gettext-domain` attribute, a schema may
* be marked for translation by adding it to `POTFILES.in`, assuming gettext
* 0.19 is in use (the preferred method for translation):
* |[
* data/org.foo.MyApp.gschema.xml
* ]|
*
* Alternatively, if intltool 0.50.1 is in use:
* |[
* [type: gettext/gsettings]data/org.foo.MyApp.gschema.xml
* ]|
*
* GSettings will use gettext to look up translations for the <summary> and
* <description> elements, and also any <default> elements which have a `l10n`
* attribute set. Translations must not be included in the `.gschema.xml` file
* by the build system, for example by using intltool XML rules with a
* `.gschema.xml.in` template.
*
* If an enumerated type defined in a C header file is to be used in a GSettings
* schema, it can either be defined manually using an <enum> element in the
* schema XML, or it can be extracted automatically from the C header. This
* approach is preferred, as it ensures the two representations are always
* synchronised. To do so, add the following to the relevant `Makefile.am`:
* |[
* gsettings_ENUM_NAMESPACE = org.foo.MyApp
* gsettings_ENUM_FILES = my-app-enums.h my-app-misc.h
* ]|
*
* `gsettings_ENUM_NAMESPACE` specifies the schema namespace for the enum files,
* which are specified in `gsettings_ENUM_FILES`. This will generate a
* `org.foo.MyApp.enums.xml` file containing the extracted enums, which will be
* automatically included in the schema compilation, install and uninstall
* rules. It should not be committed to version control or included in
* `EXTRA_DIST`.
