The logic in that function is broken. Various NULL-checking bandaids for
guaranteed non-NULL variables didn't even help there.
This patch updates the function to check if a previous item exists
before fetching it instead of after. This makes all other tests
unnecessary.
In particular, it makes the check for an empty list unnecessary, because
for empty lists the only iter is the begin iter (and the end iter) and
so the new check catches that case.

Point g-ir-scanner to the .la file of our library, which hopefully
makes it find the right dependencies in all cases (ie. our locally
built libgstreamer and not the system-installed one). This is also
how it's done in Gtk+ and how it's documented in the wiki, see
http://live.gnome.org/GObjectIntrospection/AutotoolsIntegration
Based on patches by Vincent Untz and Alan Knowles.
Fixes#603710.
Our own pkgconfig directory should come first, so that pkg-config uses
the in-tree libgstreamer and not some external one when --pkg=gstreamer-0.10
is passed to g-ir-scanner.
See #603710.
This changes some APIs in compatible ways:
- Some functions now take "const char *" arguments, not "char *"
- Some structs now have "conts char *" members, not "char *"
The changes may cause warnings when compiling with the right warning
flags. You've been warned.
Also adds -Wwrite-strings as a warning flag in configure.ac.

Adds that warning to configure.ac
Includes a tiny change of the GST_BOILERPLATE_FULL() macro:
The get_type() function is no longer declared before being defined.

This makes it >10x faster if more than a single value is requested
by not searching in the GSequence for every value and converting
the value from GValue to the real value type.
This avoids:
* triple-checking for the GType when type-checking is enabled (see #597260)
* Avoids going through an expensive no-argument checking which landed in
glib-2.22
* Avoids going through 2 extrac functions (g_object_new -> g_object_new_valist)
Use g_slide instead of nomal g_new, Also don't init struct with 0 as we need to
init it anyway with the real values.
Also join the 3 flags checks into one.
Fix a warning that occurs when the self->priv->values is NULL and
the code tries to retrieve an iterator from it. The warning was showing
up in the checks for the volume element.
When generating arrays of control changes timestamp variable was used instead
the local ts variable that we increment when stepping through the array.

Aggregate return value for gst_controller_sync_values(). More info in
logging. Always set values on first sync-call.

Original commit message from CVS:
* libs/gst/controller/gstinterpolation.c:
* libs/gst/controller/gstlfocontrolsource.c:
Use gst_guint64_to_gdouble instead of gst_util_guint64_to_gdouble
as it is mapped to a cast on non-win32 platforms.
Original commit message from CVS:
* libs/gst/controller/gstcontroller.c:
* libs/gst/controller/gstcontrollerprivate.h:
Keep last-value and only call set_property if value has changed. This
supresses all the g_object_notifies we would trigger otherwise. It
also allows the user to chage the value while there is no controller
change.
Original commit message from CVS:
* libs/gst/controller/gstinterpolationcontrolsource.c:
(_list_find_sorted_custom):
Don't use declarations after statements.
Original commit message from CVS:
* libs/gst/controller/gstinterpolationcontrolsource.c:
Optimize list handling. Use own find function. Exploit that fact that
the list is sorted. Also pass back the node before, so that we can
insert quickly. Have a fast path for append.
Original commit message from CVS:
* libs/gst/controller/gstcontroller.c:
Use freeze/thaw notify to sync notify emission a bit (its also more
efficient). Move debug output to LOG (is called a lot in a loop).
Always unset g_values if the have been initialized.

Rewrite handling of default values. Fix overflow with unsigned types
in linear interpolation. Remove now obsolete _first_value() function.
Add more tests. Fixes#538201.
