As a suggestion I would propose following change:

   Replace all
       xmlGenericError(..., msg,...)
   with
       xmlGenericErrorPlus(..., error_code, file, line, msg, ...)
   and provide new error context (callback) that'll be able
   to handle all the additional parameters (application can
   install application specific error callback).

By doing this, you provide necessary functionality
for apps who care about that and in the same time,
you have full backward API/ABI compatibility.
All the nightmares with managing context in mutltithreading
environment is left to application (it's relatievly easy in each
particular case but very hard to write a good "general" solution).
Also, the change could be done in piece (i.e. no scary big checkins).
