mostly so I can valgrind both and make sure they free all their
workspace - a memory leak in this code would be not merely an
inconvenience but a security hazard.

testdata/bignum.py is twice the size of the rest of the PuTTY source
put together, so I'm not checking it in.
This reveals bugs in the new multiplication code, which I have yet to
fix.

incorrect. I must have written that binary search idiom a hundred
times, so it's rather embarrassing that I can't _automatically_ get
it right! This was causing all kinds of characters to be classified
as ON when they should have been various other classes.
Also while I'm here, I've added another test case to utf8.txt (a
small piece of Arabic within a predominantly L->R line), and also
supplied a means to compile minibidi.c with -DTEST_GETTYPE to
produce a command-line character class lookup tool. (Not sure what
use that'll be _other_ than debugging this precise problem, but I
don't like to throw it away now I've written it :-)

going through the line and working out which bits need to be redrawn
is now in a separate loop from the subsequent activity of actually
going through and doing the redraws. This _should_ enable me to
tinker with the which-bits-to-redraw data in between the two, thus
fixing `font-overflow'. However, I thought it would be sensible to
break the work up into two commits so we can track bugs in the
restructuring separately from bugs introduced by the new feature.
Also added a couple more terminal test files.
