Use more efficient g_object_notify_by_pspec() if we're compiling against
GLib >= 2.26, and also remove work-around for g_object_notify() thread-
safety issues with older GLib versions if it's not needed any more.
Add minimal math-compath.h header where we can define fallback
versions for miscellaneous math functions that aren't always
available, so we don't have to duplicate this in plugins.
The header is not included by default, so needs to be
included explicitly for now.

Use atomic ops to read and write more properties. Taking the preroll lock in get_property
can lock up applications reading the property during preroll.
Because of the awkward refcounting in prepare_output_buffer, we might end up
with writable buffers that point to the same data. Check for those cases so that
we avoid a useless memcpy and keep valgrind quiet.
Fixes#628176
Only try to build (pseudo-)C++ unit test if a working C++ compiler has been
found, otherwise the build will fail. (We do this to make sure our headers
are 'C++ clean').
Adds a new tag to indicate the error in horizontal positioning
in meters. This is one of the available 'gps error' fields in
exif, for example.

Add a function to retrieve a list of buffers containing the first N bytes from
the adapter. This can be done without a memcpy and should make it possible to
transfer the list to a GstBufferList later.
Add gst_is_initialized() guard to gst_element_factory_make(), so
people who forgot to call gst_init() get a useful warning for what
seems to be a common enough mistake.
Sprinkle some G_UNLIKELY(), return TRUE/FALSE constants, avoid an
unnecessary g_value_unset(), move g_value_init()+set_int64_range()
closer to where they're needed.
Don't create a new GValueArray copy for every single _add_buffering_range()
call, but append to the existing value array owned by the structure instead.
Add _set_value() variants that take ownership of the value passed
instead of making a copy of the value. This is useful for setting
values to things that aren't refcounted (e.g. GValueArrays or
strings or string arrays, etc.).

Add an option to forward all the internal messages that would otherwise be
filtered such as EOS, SEGMENT and ASYNC messages.
This allows the application to, for example, detect that a partial pipeline is
prerolled or reached eos.
The original messages are wrapped inside an element message because the parent
bins are not supposed to see those internal messages escape.
