57c8e0146f libs: figure out right export define in configure
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.

46ed0f0489 libs: fix 'inconsistent DLL linkage' warnings on Windows
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.

50038bed79 gstconfig.h: add GST_API_IMPORT define
This is for use by the various GST_*_API decorators and
will be what they get defined to when a library API is being
used by external users of that library (not the library itself
whilst it's being compiled).

In most cases it will simply map to a plain 'extern' but on
Windows with MSVC it will need to map to __declspec(dllimport).
For functions this is not strictly needed, but for exported
variables it is.

01758dcf6a tests: Use a different rate in a segment test.
Using a rate of 1.1 in the test is causing the test to
fail on 32-bit because ceil(1.1 * 10) can round to 12.

Instead use a rate 2.0 that can be expressed as floating
point number and doesn't trigger the problem.

f5783e1cac pad: Accumulate live/non-live latency values separately
And only ever use the non-live values if all pads are non-live,
otherwise only use the results of all live pads.

It's unclear what one would use the values for in the non-live case, but
by this we at least pass them through correctly then.

This is a follow-up for 794944f779, which
causes wrong latency calculations if the first pad is non-live but a
later pad is actually live. In that case the live values would be
accumulated together with the values of the non-live first pad,
generally causing wrong min/max latencies to be calculated.

e975e0cae8 filesink: Remove buffer, deprecate line-buffer mode and don't use fflush()
fflush() has no effect because we use writev() directly, so fsync()

buffers.

As a next step, a non-line-buffered buffering mode is to be added.
