45ad33c94c gstgl: Porting fixes for MSVC with Meson

WINAPI should not be used with MSVC. It also causes a build error.

08e20ff131 glsyncmeta: don't glFinish() everytime a sync point is set
At minimum, we only need to glFlush() if we are in a shared GL context
environment.  Move the glFinish() to when the actual wait is requested
which may be never.  Improves the throughput on older GL systems without
GL3/GLES3 and/or fence sync objects.

126ee924c0 glwindow: don't use g_thread_join() to join the navigation thread
Using g_thread_join() in _finalize() handlers may result in a deadlock
joining the current thread when the last reference is held by a signal

485dffa6d5 gl/dispmanx: Implements set_render_rectangle to adjust the position of window
We cannot set the x, y coordinate of the video frame at the dispmanx at
this point. We need to teach dispmanx backend to understand about
set_render_rectangle API to draw a video with other UI.

This patch keeps the current behavior which places video frame at the
center of the display if there is no set_render_rectangle call to the
dispmanx window.

f678dcaf2b meson/gl: use separate deps for gl and glx
e.g. passing with_gl_api=gles2 would still build the glx code but not be
linking against the libGL library which is where the glX* functions are
located and would result in a linker error.

Solved by checking for the libGL library if either opengl or glx may be
needed and then disabling the corresponding deps as requested.

29d6825f11 glupload: fix tests and check for the new RECONFIGURE behaviour
The tests were broken since 91fea30, which changed glupload to return
GST_GL_UPLOAD_RECONFIGURE if the texture target in the input buffers doesn't
match the texture-target configured in the output caps.

cc9f65f191 gstglupload: make the GLMemoryUpload method output the correct texture-target
Now when used with video/x-raw as input, the GLMemoryUpload method checks for
->tex_target in input GLMemory(es) and sets the output texture-target
accordingly.

Fixes video corruption with a pipeline like avfvideosrc ! video/x-raw !
glimagesink where on macos avfvideosrc pushes RECTANGLE textures but glupload
was configuring texture-target=2D as output.

extra unref - the othercaps ref is consumed by
gst_caps_make_writable already.

598f8e0121 Add support for Meson as alternative/parallel build system
https://github.com/mesonbuild/meson

With contributions from:

Tim-Philipp Müller <tim@centricular.com>
Matej Knopp <matej.knopp@gmail.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.

dfd6565b4b glsl: fixup external-oes shaders by mangling the required extension
Newer devices require using a different GLSL extension for accessing
external-oes textures in a shader using the texture() functions.

While the GL_OES_EGL_image_external_essl3 should supposedly be supported
on a any GLES3 android device, the extension was defined after a lot of the
older drivers were built so they will not know about it.  Thus there are two
possible interpretations of which of texture[2D]() should be supported for
external-oes textures.  Strict adherence to the GL_OES_EGL_image_external
extension spec which uses texture2D() or following GLES3's pattern, also
allowing texture() as a function for accessing external-oes textures

This adds another mangling pass to convert
 #extension GL_OES_EGL_image_external : ...
into
 #extension GL_OES_EGL_image_external_essl3 : ...
on GLES3 and when the GL_OES_EGL_image_external_essl3 extension is supported.

Only uses texture() when the GLES3 and the GL_OES_EGL_image_external_essl3
extension is supported for external-oes textures.
Uses GLES2 + texture2D() + GL_OES_EGL_image_external in all other external-oes
cases.

ecfe5b0801 gl: implement GstGLMemoryEGL
Because current GstEGLImageMemory does not inherit GstGLMemory, GLUpload

which uses EGLImage (e.g. gst-omx in RPi).

This work adds GstGLMemoryEGL to avoid this overhead. Decoders allocate
GstGLMemoryEGL and decode its contents to the EGLImage of GstGLMemoryEGL.  And
GLUpload uses this memory without allocation of additional textures and blit
operations.

[Matthew Waters]: gst-indent the sources and fix a critical retreiving the egl
display from the memory.

614f80cbcf gl/cocoa/eagl: don't leak GThread's when dispatching messages
gst_gl_context_get_thread() returns a refed pointer, we need to unref it.

3ee2183038 glupload: keep the parent buffer around when converting EGLImage to 2D textures
e.g. receiving and releasing a buffer from OMX too early will potentially
cause textures to be overwritten while/before they are displayed.

5c506cd857 libgstgl: cocoa, eagl: use libdispatch to schedule GL calls
Use libdispatch instead of GMainLoop to dispatch GL calls. libdispatch is more
optimized and cuts a lot of poll()/pthread_* overhead.

3d124f498a glwindow: reduce the number of GMutexes and GConds in send_message()
Don't create many short lived locks/conds in gst_gl_window_send_message. This is
a micro optimization to save a bunch of pthread_* calls which are expensive on
OSX/iOS and possibly other platforms.

b1a60af720 eglimage: perform eglCreateImage in the gl thread
while calling eglCreateImage without a GL context current in the executing
thread works on the RPi, some other implementations will return errors.

Marshall the eglCreateImage to the GL thread to appease these implementations.

cbf3a986ca glviewconvert: support outputting to multiple draw buffers on GLES3
A similar change that was done to glcolorconvert adding the necessary shader
mangling.

85cddc0891 glcolorconvert: implement multiple render targets for GLES3
There are numerous slight differences required between Desktop GL and GLES3 for
multiple render targets.

1. gl_FragData doesn't exist at all and one is required to use
   'layout (location = ?) out ...' instead.
2. gl_FragColor doesn't exist, same as 1
3. texture2D() has been deprecated

Fortunately most of these have been taken care of with GL3 and the shader
mangling already exists so just expand the conditions they are used in.  The
gl_FragData issue requires a new mangle pass though.  We also use this new
pass on desktop GL for consistency.

0c2890cd34 glmemory: add checking the read implementation format/type on gles2 platforms
By default, reading GL_RED or GL_RG us unsupported by glReadPixels unless
exposed through GL_COLOR_READ_IMPLEMENTATION_FORMAT/TYPE.  This allows
downloading multiple-planar video frames where possible.

Also only unset the NEED_DOWNLOAD flag in download_transfer() if the read actually
succeeds.

ccbf43987f glshader: add glBindFragDataLocation
There are some cases where it's needed for binding in/out variables in shaders.
e.g. glsl 150 (gl 3.2) doesn't support the 'layout (location = ?)' specifiers in
the shader source so we have to bind them ourselves.

b5e8763a07 gl/proto: sync operations are available on GLES 3.0
Without the GST_GL_API_GLES2 bit set, we will not even attempt to look
for the function pointers in the core library and will fallback to
glFlush/glFinish.

b1bfcac299 glmemory: unset GL_UNPACK_ROW_LENGTH in opengl3
If the user uploads their own texture without setting the unpack length, then
then the result will have the appearance of stride mismanagement due to
an incorrect row length.

d5cc277601 glfilter: only allow the same src/sink caps when we are in passthrough mode
If we are given caps with extra features (like the overlay composition
features), we can only deal with that when we are in passthrough mode.

Previously we were bailing entirely and not allowing passthrough filter elements
with things like textoverlay.

Fixes the following pipeline (assuming glfilter supports passthrough):
gl ! textoverlay ! glfilter ! ... ! glimagesinkelement
