[alsa-devel] [PATCH 05/13] libhinawa: support GObject Introspection for language bindings

[Takashi Sakamoto]

GObject Introspection is a mechanism to give a metadata of library
to each language bindings. The library should be written by GObject
way.

This commit applies this mechanism to this library to produce language
bindings, thus adds a dependency with:
 - GObject Introspaction 1.32.1 or later

The comments in each methods and signals are important for GObject
Introspection scanner because of a hint to create better metadata.
