3eb4896435 controllers: add new proxy control binding
Allows proxying the control interface from one property on one GstObject
to another property (of the same type) in another GstObject.

E.g. in a parent-child relationship, one may need to
gst_object_sync_values() on the child and have a binding (set elsewhere)
on the parent update the value.

Note: that this doesn't solve GObject property forwarding and must be
taken care of by the implementation manually or using GBinding.

b2f9808722 Add support for Meson as alternative/parallel build system
https://github.com/mesonbuild/meson

With contributions from:

Tim-Philipp Müller <tim@centricular.com>
Mathieu Duponchelle <mathieu.duponchelle@opencreed.com>
Jussi Pakkanen <jpakkane@gmail.com> (original port)

Highlights of the features provided are:
* Faster builds on Linux (~40-50% faster)
* The ability to build with MSVC on Windows
* Generate Visual Studio project files
* Generate XCode project files
* Much faster builds on Windows (on-par with Linux)
* Seriously fast configure and building on embedded

... and many more. For more details see:

http://blog.nirbheek.in/2016/07/building-and-developing-gstreamer-using.html

Building with Meson should work on both Linux and Windows, but may
need a few more tweaks on other operating systems.

8487133114 controlpoint: change the padding to be of arch-independent size
The default padding I introduced in d4f81fb4e6 is
actually only 4 pointers and on 32bit platforms already smaller than the union.
Replace it with a fixed 64byte padding. Don't add the normal padding for now.

Fixes #755822

d4f81fb4e6 controller: add the missing abi padding
While this technically is an abi break, we decided to do this:
1) the struct is documented to be internal
2) the struct is alloced and freed inside the library
3) there are no public methods that receive or return instances
4) the only code known to use this struct are classes containd here

1a02a59e42 timedvaluecontrolsource: Add some signals about values changes
In order for user to be able to track changes in the value set in
GstTimedValueControlSource the following signals have been added:
 * value-added
 * value-removed
 * value-changed

To be able to use a GstControlPoint to be marshalled into the signals,
the GstControlPoint structure is now registerd as a GBoxed type.

New API:
~~~~~~~
  * GstTimedValueControlSource::value-added
  * GstTimedValueControlSource::value-removed
  * GstTimedValueControlSource::value-added

d4f6c8e0e6 controller: fixes int overflow with properties that span +-INT_MAX
When the range for a property is defined as -INT_MAX-1 .. INT_MAX, like
the xpos in a videomixer the following expression in the macro
definitions of convert_g_value_to_##type (and the equivalent in
convert_value_to_##type)

v = pspec->minimum + (g##type) ROUNDING_OP ((pspec->maximum - pspec->minimum) * s);

are converted to:

v = -2147483648 + (g##type) ROUNDING_OP ((2147483647 - -2147483648) * s);

(2147483647 - -2147483648) overflows to -1 and the net result is:

v = -2147483648 + (g##type) ROUNDING_OP (-1 * s);

so v only takes the values -2147483648 for s == 0 and 2147483647
for s == 1.

Rewriting the expression as minimum*(1-s) + maximum*s gives the correct
result in this case.

64eee27ebc Use GST_*_1_0 environment variables everywhere
The _1_0 suffixed environment variables override the
non-suffixed ones, so if we're in an environment that
sets the _1_0 suffixed ones, such as jhbuild, we need
to set those to make sure ours actually always get
used.
