When the range for a property is defined as -INT_MAX-1 .. INT_MAX, like
the xpos in a videomixer the following expression in the macro
definitions of convert_g_value_to_##type (and the equivalent in
convert_value_to_##type)
v = pspec->minimum + (g##type) ROUNDING_OP ((pspec->maximum - pspec->minimum) * s);
are converted to:
v = -2147483648 + (g##type) ROUNDING_OP ((2147483647 - -2147483648) * s);
(2147483647 - -2147483648) overflows to -1 and the net result is:
v = -2147483648 + (g##type) ROUNDING_OP (-1 * s);
so v only takes the values -2147483648 for s == 0 and 2147483647
for s == 1.
Rewriting the expression as minimum*(1-s) + maximum*s gives the correct
result in this case.

The current documentation is controverse, while it states that the
returned value is valid only while the query is is valid, which presumes
a 'transfer none' policy. But the tooltip for the 'out' annotation
states the default is 'transfer-full'.
Add the missing 'transfer none' annotations to fix this.

gst/gstquery.c
When we asynchronously go from READY to PLAYING, also call the
state change function so that subclasses can update their state for PLAYING.
Because the PREROLL lock is not recursive, we can't make this without
races and we must assume for now that the subclass can handle concurrent calls
to PAUSED->PLAYING and PLAYING->PAUSED. We can make this assumption because not
many elements actually do something in those state changes and the ones that
did would be broken even more without this change.

Fixes compiler warnings such as
gstallocator.c:61:8: error: conflicting types for 'gst_memory_alignment'
../gst/gstallocator.h:52:18: note: previous declaration of 'gst_memory_alignment' was here
API: GST_PLUGIN_STATIC_DECLARE()
API: GST_PLUGIN_STATIC_REGISTER()
Based on a patch by Håvard Graff <havard.graff@tandberg.com>.
This now allows GST_PLUGIN_DEFINE() to create a static plugin if
GST_PLUGIN_BUILD_STATIC is defined. The resulting plugin can be
statically linked or dynamically linked during compilation but
can't be dynamically loaded during runtime.
Also adds GST_PLUGIN_STATIC_DECLARE() and GST_PLUGIN_STATIC_REGISTER(),
which allows to register a static linked plugin easily.
It is still required to manually register every single statically linked
plugin from inside the application as this can't be automated in a portable
way.
A new configure parameter --enable-static-plugins was added that allows
to build all plugins we build here as static plugins.
Fixes bug #667305.
Very often, when the end of a segment is detected by demuxer, the position
is slightly outside the segment boundaries. Currently, if that is the case
the base will be set to NONE instead of normal accumulation. This would
break non-flushing seeks in oggdemux and most likely other demuxers.

gst_pad_get_current_caps() on the source pad might yield NULL caps
if we're being shut down and the source pad has already been
deactivated by the other thread that's changing state. Just bail
out in that case, instead of passing NULL caps to the transform_size
function, which it might not expect.
Fixes spurious warnings in audioresample shutdown unit test.
