[Alpha Patch 1/2] test: add (currently broken) test 8 bit characters hex-escape and dump-restore

[David Bremner <david@tethera.net>]

From: David Bremner <bremner@debian.org>

The problem is a use of signed chars in places where unsigned
chars (i.e. 0-255) should be used.

Well, I did mention more tests were needed ;). I failed to test 8 bit
(>127) stuff and sure enough it was broken.  This sets up some tests
to demonstrate the problem and the next patch fixes it.
