d108ed2251 gst: check non-null before dereference
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.

fe3180dcca debug: Instantiate GType when dumping debug categories.
A lot of debug categories are declared in element class_init
functions, which don't get run until the element is first created
(not just registered in the plugin load function). This means
that --gst-debug-help doesn't print out a lot of categories.

Creating an instance of each element from the element factory
makes them visible, at some extra cost - 2-3 times longer, which can
be a full second or two of extra waiting. Yikes!

b174ec6903 gst/gst.c: Add a warning about DllMain to prevent misuse
DllMain should not be relied on for anything except storing the DLL handle.
It should also not be defined for static builds, but doing so is not
straightforward and is mostly harmless, so let's just add a comment about that
for now.

bc282da83c segment: remove the bounds check from _to_running_time_full()
Do not do any checks for the start/stop in the new
gst_segment_to_running_time_full() method, we can let this be done by
the more capable gst_segment_clip() method. This allows us to remove the
enum of results and only return the sign of the calculated running-time.
We need to put the old clipping checks in the old
gst_segment_to_running_time() still because they work slightly
differently than the _clip methods.

4c66d08d08 gst: ensure GStreamer initialization debug message is displayed
The GST_INFO ("initialized GStreamer succesfully") is currently at the end of
gst_init_check which isn't guaranteed to be run since GStreamer can be
initialized by using init_pre and init_post directly from GOptionContext like
gst-launch does. Ensure this message is displayed by moving it to init_post.

but can be installed in
<parent_folder_of_gstreamer_main_dll>\lib\<debug>\gstreamer-$(GSTApiVersion),

7fc2602761 gst: Don't intercept --help in gst_init()
Before this patch gst_init would intercept --help, causing for example
cheese's --help to look like this:

[hans@shalem cheese]$ cheese --help
Usage:
  cheese [OPTION...] - GStreamer initialization

Help Options:
  -h, --help                        Show help options
  --help-all                        Show all help options
  --help-gst                        Show GStreamer Options

gst_init is the only gfoo_init function which does this.

9326124581 gst: Don't set the locale in gst_init()
The function init_pre() in gstreamer/gst/gst.c calls setlocale(LC_ALL, ""),
which sets the locale to the values specified in the environment.  This is
wrong for two reasons:

1. It is absolutely not the task of a library to decide on the correct locale
for a program.  Some programs change the locale for various (good or bad)
reasons, and libraries should respect that.  Programs where GStreamer's
overwriting of the locale causes bugs include Emacs [1, 2], Sublime Text [3],
and Lua [4].

[1] http://debbugs.gnu.org/cgi/bugreport.cgi?bug=12392
[2] http://bugzilla.novell.com/show_bug.cgi?id=779426
[3] http://www.sublimetext.com/forum/viewtopic.php?f=3&t=8543
[4] https://github.com/pavouk/lgi/issues/19

Note that setting the locale can cause problems for programs that are not even
linked against GStreamer.  In the case of Emacs, for example, GStreamer seems
to be initialized through GTK via libcanberra.

2. Setting the locale is not thread-safe, and therefore should not be done in a
library.
