[Octave-bug-tracker] [bug #57033] Replace CXSPARSE with SPQR

[Markus Mützel]

Follow-up Comment #44, bug #57033 (project octave):

The attached patch adds more checks on converting between different integer
types and uses the necessary integer pointer types.

I'm unsure where to add the new function `from_size_t` and whether that is a
good name for a function that checks whether the input can be safely converted
from `size_t` to `octave_idx_type`.
The function `from_suitesparse_long` is probably in the correct file
(oct-sparse.h). But same doubt about the name.

Compiles for me with gcc on Ubuntu, and the test suite passes.
I haven't tested if this would fix building for the Win32 target.
