[PATCH 00/16] Update Grilo to build on GI's HEAD and other fixes

[Simón Pena <spenap gmail com>]

Hi all,

The following set of patches fix some issues which prevented Grilo to be
built with introspection support in GI versions newer than 0.9.3, by

* modifying the type and element-type annotations to remove the '*' from
  the data types
* adding an explicit "transfer mode" to return values of non-basic types
* modifying the declaration of the GrlPluginInfo structure so the typedef
  appears prior the struct declaration.

Besides, aiming to reduce the number of non-introspectable functions, 
the following changes have been made:
* the GrlMetadataSource class has been annotated
* GrlMediaPlugin defines have been replaced with functions
* GrlMetadataSource callbacks' GErrors have been annotated as uints
* Other annotation fixes

And finally, following Edu's advice to reduce the number of annotations 
to the minimum needed, those related to functions returning "const gchar*"
have been removed, as they're "(type utf8") (transfer none)" by default.

As a bonus, a check is introduced to avoid invoking key-depends on plugins
which don't have it implemented.
