#13502: vector norm doesn't work with python integers
------------------------------+---------------------------------------------

------------------------------+---------------------------------------------
Since there is a (1/p) calculation in the Cython file, if p is a python
integer, that (1/p) is 0 (since 1 is also a python integer).
This fix is to make the 1 in 1/p actually a Sage integer, which does the
right thing. The 1 is cached at the module level.
Example of wrong behavior:
{{{
sage: v = vector(QQ, [1,2])
sage: v.norm(int(2))
1
}}}
