xwm: Add an X11 error tracing infrastructure

Browse source 
This adds some infrastructure that records the current X11 sequence
number, file name, and line number at various places. When an X11 error
later comes in, this tracing infrastructure can use the sequence number
of the error to figure out which piece of code caused this X11 error.
