Instead of using BaseSrc default format GST_FORMAT_BYTES, send it in
GST_FORMAT_TIME.

Fixes#611659
The compiler wants a cast here even though the type is already
typedefed as 64-bit integer (presumably because glib has typedefed
guint64 to unsigned long here).
Don't leak a string everytime get_uri() is called and a device
has been set. There's a limited number of devices, so just
intern the string instead of doing more elaborate housekeeping
and storing it in the instance struct or so.
Old videodevice2.h kernel headers used ioctl stuff without
including ioctl.h, making compilation fail on older systems.
Note: Including ioctl.h here is only a workaround for old kernel
headers, should be removed once everybody has new enough headers.
Fixes bug #597867.
For cameras/drivers that don't support e.g. VIDIOC_G_PARM we'd end up without
a framerate and would try to divide by 0, causing run-time warnings and all
frames to be timestamped with 0, which makes sinks that sync against the clock
drop them, causing 'hangs' (observed with the pwc driver and a Logitech QuickCam
Pro 4000). So if we do not know the framerate, simply don't adjust the
timestamps. Fixes#591451.
Clear format list and probed caps when going to NULL so if a new device
is set we'll probe the formats again instead of using previously
detected ones. Fixes bug #591747.
It seems to cause strange occasional high latencies (almost 200ms) when dequeuing buffers from _buffer_alloc(). It is simpler and seems to work much better to dqbuf from the same thread that is queuing the next buffer.
This also does the following changes:
(1) pull the bufferpool code out into gstv4l2bufferpool.c, and make a
bit more generic so it can be used both for v4l2src and v4l2sink
(2) move some of the device probing/configuration/caps stuff into
gstv4l2object.c so it does not have to be duplicated between
v4l2src and v4l2sink
Fixes bug #590280.
The v4l2 driver for USB webcams on OpenSolaris does not support select()
calls. Detect when select() fails, and skip polling the device afterward,
which restores the pre 0.10.14 behaviour on OpenSolaris.

We need a cast here for pointer arithmetic to work correctly, but some
MSVC versions don't seem to like 'byte', so use guint8 here. Hopefully
fixes#585361.
Fix the setting of toggle switches on some broken audio drivers which
report that no audio ports are settable by ignoring the mod_port field
there.
Add some debug statements.
Fix a FIXME now that Good relies on a new enough gst-plugins-base.
Use new audio mixer flags added in Base 0.10.23 to expose flags and options
on the SunAudio devices.
