xcb: Remove useless error handling
All the *_reply() functions in XCB return a pointer to their result and as last
argument they get a xcb_generic_error_t** where pointers to errors are stored,
if any occurs.
However, a request can either fail or succeed. This means that if the returned
result is a NULL pointer, then an error occurred and the other way around: If
the error pointer is set to non-NULL, then the function must have returned NULL.
Thus, all the code, which just checks if an error occurred and which does not
care about the exact error code, does not need to get the error pointer at all.
In this case, xcb will free() the error internally.
While doing this, I noticed that _cairo_xcb_connection_get_image() always
succeeds and thus its return value can be replaced with the GetImage result.

check-doc-syntax: Don't hardcode path to awk
Instead of expecting awk in /usr/bin, this commit changes the code to call awk
through a shell so that $PATH is searched.
Since this awk script shouldn't really be called manually, this is done by
removing the shebang from the awk script, marking it non-executable and fixing
up the caller.

cairo-gobject: Require at least glib 2.14
cairo-gobject uses g_once_init_enter() and g_once_init_leave(). These functions
were added in glib 2.14 and thus cairo needs at least this version for its
gobject helper functions.
