From: Jeff Dike <jdike@addtoit.com>

This is a large set of small fixes and other changes:

Fixed a file descriptor leak in the network driver when changing an IP
address.

The port channel now sets SO_REUSEADDR.

Added some initcall and exitcall definitions to arch/um/include/init.h
so that they can be used from userspace code.

Fixed the error handling in run_helper.

Added the log() facility to mem_user.c.

Fixed a problem with recursive segfaults not being handled correctly.

tty_log_fd and umid aren't added to the command line any more.

Fixed some prints.
