__declspec(dllexport/import) are supported by GCC and are needed for
properly generating code that fetches the values of constants from DLLs
built with __declspec(dllexport) which happens when anything using
GST_EXPORT is built with MSVC.
See: https://msdn.microsoft.com/en-us/library/619w14ds.aspx
Essentially, if you built gstreamer with MSVC and then tried to use
constants from it (such as GST_TYPE_CAPS) in a plugin, GCC would
retrieve the address of the value instead of the value itself.
and remove all the printf extension/specifier stuff for
the system printf. Next we need to add back the custom
specifiers to our own printf implementation.

Since everything GstXML related has been deprecated, we can now skip the
libxml includes from the public headers when GST_DISABLE_DEPRECATED is
defined.
See #463435.
Force printf format checking for debug messages if GST_DISABLE_PRINTF_EXTENSION
is defined. This is useful to quickly check code for printf format mismatches
in debugging messages that would usually not be caught (with glibc+gcc and
printf extensions being used).
To use: make clean; make CFLAGS='-g -O2 -DGST_DISABLE_PRINTF_EXTENSION'

Remove GST_DISABLE_(ENUMTYPES|INDEX|URI) everywhere.
Disabling the indexers and URI handler code will only reduce the
required amount of memory by a very small amount but on the other hand
requires much more maintaince work. Apart from that many places of
code are broken when disabling them.
Disabling the enum types doesn't reduce the required amount of memory
by more than a few bytes and makes it hard to fix bugs like #539772,
i.e. use the enums as GObject properties.

Move registry backend API to private headers where we can. Add
fixme-0.11 comments for the others. Add stubs for the xml backend when
using the binary to ensure they functions exists (they should not be
used though). Fixes#520756.

Fix broken use of config.h-defined preprocessor directive in a public

really remove those function declarations from the header file now
(or can we? and why are they there in the first place?).

Add GST_USING_PRINTF_EXTENSION to gstconfig.h so that we know
whether we can use G_GNUC_PRINTF in other header files and at
least check the printf format/arguments of debug messages and
GST_ELEMENT_ERROR messages when the printf extension is not
being used.
Replace more tabs with spaces in gstinfo.h and remove two spurious
function declarations in GST_DISABLE_DEBUG part with macros.

- totally reworked type(find) system
- bytestream is out of the core again
- typefind element is now part of gstelements
Original commit message from CVS:
GST_DEBUG reorganization
This is a big diff (ca 450k), containing loads of stuff:
- gstinfo.[ch] complete rewrite
- changing of all GST_DEBUG messages to reflect that change
- reorganization of subsystem disabling
- addition of gstconfig.h.in so we can track the disablings
- <gst/gst.h> does not include <unistd.h> and <config.h> anymore
- documentation updated for gstinfo stuff (build the docs yourself to know what changed)
- bugfixes for making of the docs (files from CVS are not deleted anymore
- testsuite for debugging changes in testsuite/debug
expect breakage
