x11_common: do not set custom error handler when calling XSelectInput

Do this because we want to remove the global variables required with the
old code. In particular, there doesn't seem any way to set a secure user
data pointer with xlib.

XSelectInput() causes a BadAccess error when some of the requested event
flags are reserved (for exclusive flags like ButtonPress). The custom
error handler caught this and set a global variable, so that the code
could retry the XSelectInput() call without the conflicting flags. Use a
different approach that doesn't need a custom error handler. (Although
we still assume that the error handler doesn't terminate the program.)
