/*@C
   PetscMPIAbortErrorHandler - Calls MPI_abort() and exits.

   Not Collective

   Input Parameters:
+  comm - communicator over which error occurred
.  line - the line number of the error (indicated by __LINE__)
.  file - the file in which the error was detected (indicated by __FILE__)
.  mess - an error text string, usually just printed to the screen
.  n - the generic error number
.  p - PETSC_ERROR_INITIAL if error just detected, otherwise PETSC_ERROR_REPEAT
-  ctx - error handler context

   Level: developer

   Notes:
   Most users need not directly employ this routine and the other error
   handlers, but can instead use the simplified interface SETERRQ, which has
   the calling sequence
$     SETERRQ(comm,n,p,mess)

   Notes for experienced users:
   Use PetscPushErrorHandler() to set the desired error handler.  The
   currently available PETSc error handlers include PetscTraceBackErrorHandler(),
   PetscMPIAbortErrorHandler(), PetscAttachDebuggerErrorHandler(), and PetscAbortErrorHandler().

   Concepts: error handler^stopping
