An untested pointer segfaulted in webkit while playing video
on imx6 sabrelite. It turned out that the imx plugin didn't
implement the meta transform function.
The following GST_DEBUG trace was visible:
gstbasetransform.c:1779:foreach_metadata:<conv2> copy metadata
GstImxVpuBufferMetaAPI
Thread 26 vqueue:src received signal SIGSEGV, Segmentation fault.

It is possible to use gst_deinit() without registering the base
classes. For example, when using gst_init_get_option_group() and
call the program with an invalid parameter. In that case,
gst_deinit() will lead to a segmentation fault, since there is a
dereference to a pointer that is null.
This patch validates if the type is non-null before dereferencing
it.

This unbalanced closing parenthesis is leftover from the commit
8b739d91e7. It used to wrap the caps but we don't seem to do that in
the current code.
So, just remove it. No functionality has been changed.

Use g_object_new() instead which nowadays has a shortcut for the
no-properties check. It still does an extra GType check in the
function guard, but there's a pending patch to remove that
and it's hardly going to be a performance issue in practice,
even less so on a system that's compiled without run-time checks.
Alternative would be to move to the new g_object_new_properties()
with a fallback define for older glib versions, but it makes the
code look more unwieldy and doesn't seem worth it.
Fixes deprecation warnings when building against newer GLib versions.

They were (signed!) gint64 before because of G_GINT64_CONSTANT() already
and they are actually used in signed calculations.
With this change we at least ensure that an integer type of the correct
size is used for GI (it was using gint before).
In GES, the summary refers to options that are only available when built
against gst-valdiate. Those where picked by our regex. This patch add a
initial grep to try and filter-out as best as possible the content to
which we will extract the command list.
This patch reorganize the bash completion scripts in order to install
the binary helper (gst-completion-helper) in libexec path rather then
share folder. Most Linux hierarchy compliance requires that no binary
executable are placed in share. We also cleanup the unused .pc entries
and remove copy pasted parts of the script. Note that other project
including the common helper, should now use $_GST_HELPER to read
the binary executable gst-completion-helper. This helper is not longer
version, as it is placed in a versionned subfolder
(libexec/gstreamer.10) just like the other helpers (scanner and ptp).
The issue happens when the structure is printed by the logging
subsystem: the object is included in the log, and this will cause the
full object printout to be done there. However, after dispose, the queue
was already cleared, so the access to it (to print the object) would
assert, as the queue was already freed. The patch changes it so that the
queue is merely empty, and only freed in _finalize.

A paramspec validation should modify the content to match what the spec
requires and return TURE if a modification happened. This previous
implementation would only fix the first element of the array and return.
It was also return TRUE for empty array, while no modification was
needed.

The GST_TYPE macro points to global variables initialized by the
first call to get_type. This is not an issue if you call gst_init()
but unfortunatly pygi will need to acces the param type before
init can be called. This removes an assertion.
Those aren't suppose to be called from multiple thread, but all
fundamental get_type() function are thread safe. Fix it to
be consistent and it may help if we change the typing mechanism
in GStreamer come day.
