mescc: Output performance hacks: use core:display.

Browse source 
* src/lib.c (display_): Write to g_stdout (WAS: STDOUT).
* module/mes/guile.scm (guile): Declare and export core:display core:display-error.
* module/mes/M1.mes (object->M1): Use core:display and string-append
  instead of format.
* module/mes/guile.mes (with-input-from-string): Add debugging.
  (open-input-string): Likewise.
  (read-string): Likewise.  Re-implement.
  (drain-input): Use read-string.
