bigint.c: bintRadixFrString fix sign issues = ires should be unsigned.
Also add bigint test suite (as usual, incomplete, but better than nothing).
tform.c: Missing a header file.
aldortest: write to stderr (no reason for this as such, just that it did
previously)
axldem tests: intfact no longer broken (or at least produces believable
results).
build: testprog.am now makes the resulting Makefile depend on Tests.am..
this way adding a test will update the makefile.
axllib: add textread to build
Add definition of equality on list - not really that useful, just to make
some tests work.
Add a target to build Makefile to testprog directories.
Remove the special case map processing from gen0RtTypeHash.
Also support the case where the type is an unknown tuple (see bug818).

Doing this means that the code in bug818 will correctly find exports, but
is still unable to call the export with any success; unfortunately we
don't have a way of applying a function in a generic context.

bug818 itself now prints a little more by way of debugging.
genfoam: Handle the case where we've called a function returning an 'Exit'
value in a context expecting a multi-valued return.  Exit here implies
that the called function will never return.  In this case we should output
the call to the function, and create a value suitable for the return
context.  Any value will do, as the code is effectively unreachable.
Replace Integer with SingleInteger
Add a few fixes for 'Internal Warning: abDefineeId comma bug' messages.
These are generally due to (a, b) forms appearing in unexpected places.

Change tiPushDefinee to work with comma forms.
whitespace fix
make clean: Remove all .al, .dep, .java, .class and .ao files; these
types may be erroneously picked up by make even if not part of the current
build.
