Switch library documentation to gi-docgen

Browse Source 
Switch from gtk-doc to gi-docgen for the library documentation and
adjust the source files accordingly.

We don't bother about the daemon doc headers as they're not built into
any docs atm.

Closes: #56

Title: Compiling with libfeedback
Slug: building
# Compiling with libfeedback
If you need to build libfeedback, get the source from
[here](https://source.puri.sm/Librem5/feedbackd) and see the `README.md` file.
## Using `pkg-config`
Like other GObject based libraries, libfeedback uses `pkg-config` to provide compiler
options. The package name is `libfeedback-0.0`.
When using the Meson build system you can declare a dependency like:
```meson
dependency('libfeedback-0.0')
```
## Bundling the Library
### Using a Subproject
Libfeedback can be used as a Meson subproject. Create a
`subprojects/libfeedback.wrap` file with the following contents:
```ini
[wrap-git]
directory=libfeedback
url=https://source.puri.sm/Librem5/feedbackd.git
revision=main
depth=1
```
Add this to your `meson.build`:
```meson
libfeedback = dependency(
'libfeedback-0.0',
version: '>= 0.0.1',
fallback: ['libfeedback', 'libfeedback_dep'],
default_options: [
'daemon=false',
'man=false',
'gtk_doc=false',
'vapi=false',
'tests=false',
]
)
```
Then the `libfeedback` variable can be used as a dependency.
# Next Steps
Once libfeedback has been compiled and included into your project, it needs to be
initialized. See [Initialization](initialization.html).

Title: Initialization
Slug: initialization
# Initialization
Before using libfeedback, it must be initialized. To use the library
call [func@Lfb.init]() with the id of your application (usually
the desktop file name without the .desktop extension). For that you
include the `libfeedback.h` header. Since the API is considered
unstable at this point in time you need to acknowledge this by
definining `LIBFEEDBACK_USE_UNSTABLE_API`:
```c
#define LIBFEEDBACK_USE_UNSTABLE_API
#include <libfeedback.h>
int main(void)
{
g_autoptr (GError) *err = NULL;
if (lfb_init ("com.example.appid", &err)) {
g_error ("%s", err->message);
}
...
lfb_uninit ();
return 0;
}
```
You can also acknowledge this with the definition option of your C
compiler, like `-DFEEDBACK_USE_UNSTABLE_API`.
After initializing the library you can trigger feedback using
[class@Lfb.Event] objects. When your application finishes call
[func@Lfb.uninit]() to free any resources:

Title: Overview
Slug: Overview
# Libfeedback Introduction
The purpose of libfeedback is to make it simple to supply audible,
haptic and visual feedback to the user. This is done by
notifying a feedback_daemon over DBus that a certain event
happened. The daemon then selects the appropriate feedbacks (such
as a buzzing haptic motor or playing an audio file) based on the
user session's current feedback profile, feedback theme and
available hardware.
Events are identified by strings like `message-new-sms` or
`message-new-sms`. The available event names are described in the
[Event naming specification](Event-naming-spec-0.0.0.html).
Libfeedback provides synchronous and asynchronous APIs to trigger and
stop feedback for these events and is usable from other languages than
C by GObject introspection.
See [Compiling with libfeedback](build-howto.html) on how to include
libfeedback in your project.

<title>Compiling libfeedback applications</title>
<simplesect>
<title>Using pkg-config</title>
<para> Like other GNOME libraries,
<application>&package_string;</application> uses
<application>pkg-config</application> to provide compiler options. The
package name is
"<literal>&package_ver_str;</literal>". So in
your <literal>configure.ac</literal> script, you might specify something
like: </para>
<informalexample><programlisting>
PKG_CHECK_MODULES(LIBFEEDBACK, [&package_string;-&package_api_version;])
AC_SUBST(LIBFEEDBACK_CFLAGS)
AC_SUBST(LIBFEEDBACK_LIBS)
</programlisting></informalexample>
</simplesect>
<simplesect>
<title>Using Meson/Ninja</title>
<para>
If using Meson/Ninja use a <literal>dependency('&package_string;-&package_api_version;')
</literal> dependency.
</para>
<para>
The "<literal>&package_api_version;</literal>" in the package name is the "API version"
(indicating "the version of the <application>&package_string;</application> API
that first appeared in version &package_api_version;") and is essentially just part of
the package name.
</para>
<para>
When using the Meson build system you can declare a dependency like
</para>
<informalexample><programlisting>
dependency(libfeedback-0.0')
</programlisting></informalexample>
</simplesect>
<simplesect>
<title>Acknowledge the Instability</title>
<para>
Since the library is young and is still changing a lot, in order to use it you are required to acknowledge that your are using an unstable API.
To do so, <literal>LIBFEEDBACK_USE_UNSTABLE_API</literal> must be defined for compilation to succeed.
</para>
<para>
From C code or any compatible language, you can prefix your inclusion of the &package_string; header like so:
</para>
<informalexample><programlisting>
#define LIBFEEDBACK_USE_UNSTABLE_API
#include &lt;libfeedback.h&gt;
</programlisting></informalexample>
<para>
Including individual headers rather than <literal>libfeedback.h</literal> is not
recommended.
</para>
<para>
You can also acknowledge this with the definition option of your C compiler, like <literal>-DFEEDBACK_USE_UNSTABLE_API</literal>.
This is required from Vala.
</para>
<para>
To use &package_name; from Vala, you must define the acknowledgment in C via <literal>-X -DFEEDBACK_USE_UNSTABLE_API</literal>.
If your build system uses a two pass compilation and hence your Vala compiler outputs C (Meson, Automake, or using the <literal>--ccode</literal> Vala compiler option trigger that) then you must add <literal>-DLIBFEEDBACK_USE_UNSTABLE_API</literal> to your C compiler arguments instead.
