b6411ae74c libs: fix API export/import and 'inconsistent linkage' on MSVC
For each lib we build export its own API in headers when we're
building it, otherwise import the API from the headers.

This fixes linker warnings on Windows when building with MSVC.

The problem was that we had defined all GST_*_API decorators
unconditionally to GST_EXPORT. This was intentional and only
supposed to be temporary, but caused linker warnings because
we tell the linker that we want to export all symbols even
those from externall DLLs, and when the linker notices that
they were in external DLLS and not present locally it warns.

What we need to do when building each library is: export
the library's own symbols and import all other symbols. To
this end we define e.g. BUILDING_GST_FOO and then we define
the GST_FOO_API decorator either to export or to import
symbols depending on whether BUILDING_GST_FOO is set or not.
That way external users of each library API automatically
get the import.

While we're at it, add new GST_API_EXPORT in config.h and use
that for GST_*_API decorators instead of GST_EXPORT.

The right export define depends on the toolchain and whether
we're using -fvisibility=hidden or not, so it's better to set it
to the right thing directly than hard-coding a compiler whitelist
in the public header.

We put the export define into config.h instead of passing it via the
command line to the compiler because it might contain spaces and brackets
and in the autotools scenario we'd have to pass that through multiple
layers of plumbing and Makefile/shell escaping and we're just not going
to be *that* lucky.

The export define is only used if we're compiling our lib, not by external
users of the lib headers, so it's not a problem to put it into config.h

Also, this means all .c files of libs need to include config.h
to get the export marker defined, so fix up a few that didn't
include config.h.

This commit depends on a common submodule commit that makes gst-glib-gen.mak
add an #include "config.h" to generated enum/marshal .c files for the
autotools build.

cea5e3fcdb meson: Maintain macOS ABI through dylib versioning
Requires Meson 0.48, but the feature will be ignored on older versions
so it's safe to add it without bumping the requirement.

700d6782ce codecparsers: mpeg2: don't mess the StartCode only packets
It is completely legal to have packets with zero sizes.
Zero-sized packet indicates header with only Start Code.
One eg: is user data packet. The patch allows having
GstMpegVideoPacket with zero sizes.

a05006944a codecparsers: GST_EXPORT -> GST_CODEC_PARSERS_API
We need different export decorators for the different libs.
For now no actual change though, just rename before the release,
and add prelude headers to define the new decorator to GST_EXPORT.

d252f503fc h265parser: decouple GstH265Profile and GstH265ProfileIDC
We used to have the same enum to represent H265 profiles and idc values.
Those are no longer the same with extension profiles defined from
version 2 of the spec.
Split those enums so the semantic of each is clearer and we'll be able
to add extension profiles to GstH265Profile.

Also add gst_h265_profile_tier_level_get_profile() to retrieve the
GstH265Profile from the GstH265ProfileTierLevel. It will be used to
implement the detection of extension profiles.

cedc7d4def codecparser: vp8: Fix range decoder init
According to the vp8 spec, the first partition (size can be derived from
the frame header) should have all compressed header information and we
implemented gst codecparser based on that. But it doesn't seem to be the
case with some of the streams (#792773) and libvpx
works fine because it uses the whole frame size (not the first partition
size) to initialize the bool decoder.

95c842a860 codecparsers: remove problematic 'extern inline'
'extern inline' was added in 2fb76c89 for MSVC (it was just
'inline' before), but all of this doesn't really make sense,
the functions are not going to be inlined anyway, and what
'extern inline' means exactly also appears to depend on the
Cxx standard targetted. Let's just remove the 'extern inline'
entirely. At least gcc6 still emits the exact same code as
before anyway. Fixes compilation/linking with gcc 4.8 as
used on L4T on the TK1.

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.

5ebf1d477d mpegvideoparser: Handle non-hierarchical profiles again
This is a regression from since mpegvideoparser was switched to
use the codecparsing library.

The problem is that the high bit of the profile_and_level is used
to specify non-hierarchical profiles and levels. Unfortunately we
were discarding that information.

Expose that escape bit, and use it in the element
