Avoid unnecessary value copying, and unnecessary init/unset
cycles which all go through the value table. There's a bunch
of places where we copy a value and then unset it in the next
line, instead of just taking over the source value.
Add a GST_BIN_FLAG_NO_RESYNC that disables a resync when an element is added,
removed or linked in the bin. This is interesting for complex bins that
dynamically add elements to themselves and want to manage the state of those
elements without interference from resyncs.

The control of wheteher a SingleQueue is full is not correct.
Rewrote single_queue_overrun_cb() so it checks the correct variables
when checking if the queue has reached the hard limits, and to
increase the max buffer limit once for each call.

In order for 1.x and 1.(x+1) versions to not invade on each other
we need to have different lib versions.
So we need a consistent and predictable scheme:
library version number = MINOR * 100 + MICRO
Ex:
1.0.0 => 0 (duh)
1.0.3 => 3
1.1.0 => 100
1.1.1 => 101
1.2.0 => 120
1.10.5 => 1005
....
We don't need to link to gthread-2.0 any longer, since all
the normal thread-related stuff is in GLib proper, and we
don't use g_thread_init() any more.

Users of GStreamer are not generally expected to use the GModule API
directly. so don't force them all to link against it.
While we're at it, no need to define this via configure.ac really, just
put the dependencies directly into the .pc.in file.
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].

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.
