Automatically release I/O permissions on shutdown.
get_io_perms() is renamed to rget_io_perms() and automatically registers
a function to release I/O permissions on shutdown.
Actually release I/O permissions on Solaris and iopl()-supporting
operating systems like Linux.
This patch fixes quite a few programmers which forgot to release I/O
permissions on shutdown, and it simplifies the shutdown and error
handling code for all others.
Do not call exit(1) if I/O permissions are denied and return an error
instead. This part of the patch was written by Niklas Söderlund.
