Don't use snprintf(), but use sprintf instead and do our own
length calculations, because glibc may complain about us passing
%n in a format string if the string is in writable memory, and
here the format string is always in writable memory since we
construct it on the fly. This happens if glibc has been compiled
with _FORTIFY_SOURCE=2, which seems to be the case on some
distros/systems). On the upside, we now use the sprintf code path
on all systems which should be better from a maintenance point
of view.

Make GST_PLUGIN_DEFINE use G_STRINGIFY() to convert the name argument
into a meaningful string. The advantage of this is that `name' can be
expanded from other macros defined in the plug-in element.

Don't use just GLIB_HAVE_ALLOCA_H to check if alloca is available,
that's just for the header. GLib may define alloca for us otherwise
too irrespective of GLIB_HAVE_ALLOCA_H.
Fixes compiler warning with mingw32:
gst/printf/vasnprintf.c:73:0: warning: "alloca" redefined
Does not do anything yet. On a sidenote, we can't just use
%p\001 or so to signal the extension because g-i complains
about an invalid ascii character then, so have to resort to
something more elaborate, such as %p\aA etc.

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.

We will add support for our own printf modifiers, so we can
get nice debug log output on all operating systems irrespective
of the specific libc version used.

Wait for all PROGRESS messages (if any) to complete before going to the PLAYING
state. This is the only way we can wait for live elements to complete their
operations.
This is interesting for elements like rtspsrc that do some asynchronous network
requests as part of going to the PAUSED state. It could be possible that it, for
example, provides a clock and then we would like to wait until it completes
so that we can use the provided clock when going to PLAYING.
libwinpthreads provides POSIX time API.
It also provides libpthread alias for itself, for compatibility, so that
is what we will link with.

These account for both possible type size mismatch AND -mms-bitfields
packing. Sizes are taken from an i686-w64-mingw32-built GStreamer,
gcc 4.8.0, mingw-w64 svn-r5685.
Fixes#697551
Iterate over the fields of the superset instead of those of the subset.
This way we can check the presence of the subset field and do the subset check
in one iteration.
