#9402: Extend dokchitser L-function package in Elliptic Curves to Number Fields

Comment(by adam):
Use lseries_num_fields2.patch, the second one. This adds documentation and
fixes a bug in the first one.
The bug fixed is that the elliptic curve E was calling
E.reduction(prime_ideal).count_points() where prime_ideal is a prime of
good reduction but E is not minimal with respect to that ideal; i.e., that
ideal's norm divides the conductor of E.
The fix first checks that E is minimal with respect to said ideal. If not,
E.local_minimal_model(prime_ideal).reduction(prime_ideal).count_points()
is calles.
