[ublas] [patch] fix some small bugs

Hello Michael,

the attached patch (against current HEAD) fixes some small bugs:

1. coordinate_matrix::set_filled() does not compile because of the return 
statement. Removing that is not enough, because sorted_ and sorted_filled_ 
are not adjusted and storage_invariants() fails.

2. coordinate_matrix::sort() generates compiler warnings about signedness if a 
signed index array is used.

3. Two versions of axpy_prod() do not compile because of copy and paste errors 
(one of them can be detected using Karls ublas_axpy_prod.cpp that he sent on 
2004-07-15 - it should really be incorporated into the existing tests)

Please apply (at least the compile error fixes).

Georg
