Add pretty-printer for errno. zack/errno-prettyprint
This patch adds the actual pretty-printer for errno. I could have used Python's built-in errno module to get the symbolic names for the constants, but it seemed better to do something entirely under our control, so there's a .pysym file generated from errnos.texi, with a hook that allows the Hurd to add additional constants. Then a .py module is generated from that plus errno.h in the usual manner; many thanks to the authors of the .pysym mechanism. There is also a test which verifies that the .py file (not the .pysym file) covers all of the constants defined in errno.h. hurd-add-errno-constants.awk has been manually tested, but the makefile logic that runs it has not been tested. * stdlib/errno-printer.py: New pretty-printer. * stdlib/test-errno-constants.py: New special test. * stdlib/test-errno-printer.c, stdlib/test-errno-printer.py: New pretty-printer test. * stdlib/make-errno-constants.awk: New script to generate the .pysym file needed by errno-printer.py. * stdlib/Makefile: Install, run, and test all of the above, as appropriate. * sysdeps/mach/hurd/hurd-add-errno-constants.awk: New script to add Mach/Hurd-specific errno constants to the .pysym file used by stdlib/errno-printer.py. * sysdeps/mach/hurd/Makefile: Hook hurd-add-errno-constants.awk into the generation of that .pysym file.
