#1 Unofficial combined patches from 1.3.3 (1.3.4-pre-ia1)

[Ian Abbott]

Bill,

Here's a combined patch against v1.3.3 for your consideration. I've
used a temporary version number, which would of course be
changed for an official release. I don't want to step on your toes!

This patch includes the following:

- my spinlock fixes;
- some VID/PIDs for SeaLINK+ adapters (provided by Tuan Hoang,
but I removed some that don't appear to exist);
- PID for Home Electronics Tira-1 (provided by Chris Horn);
- David Norwood's patch for USB-UIRT support;
- some whitespace fixes by me - hence the slight bloatiness of the
patch.
