These parameters are incorrectly regarded as mutable in G-IR making them
"incompatible" with languages that are explicit about mutability like
Rust. In order to clean up the code and expected API there, update the
signatures here, right at the source (instead of overriding them in
Gir.toml and hoping for the best).

The XV_COLORSPACE attribute exists on some Xv adapters, with the same
semantics as the XV_ITURBT_709 attribute that was already supported.
A value of 0 is bt601, and 1 is for bt709 colorspace.
Fixes color shifting issues displaying bt709 content on some Xv
adapters.

ximagesink and xvimagesink use XkbKeycodeToKeysym when the key event is
received. However, this function returns NoSymbol if Xkb is unavailable.
This causes all key events to be translated to "unknown" key when running
ximagsink under some VNC.
Fix it by using XKeycodeToKeysym if Xkb is unavailable.
Don't try to set port attribute that's not advertised by the
adaptor. Fixes videotestsrc ! xvimagesink aborting with
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 151 (XVideo)
Minor opcode of failed request: 13 ()
on intel HD4600 graphics with kernel 3.16, xserver 1.15,
intel driver 2.21.15.
Make a new refcounted xvcontext object that handles the X connection.
Use the xvcontext to allocate images and windows. Move some code
around so that all X calls are made from the xvcontext object.
Make a GstXvImageAllocator object that allocates images from the xvcontext. We
can implement a copy function now for these memory objects now.
Make the bufferpool use the xvimageallocator object for its images.
