Changes commited to PARI GIT during the last two weeks

spurious return

1	1	src/basemath/hnf_snf.c

4- charpoly(matrix over p-adic fields): use Berkowitz in all cases

Much stabler than Hessenberg form, not much slower.

TODO: A _fast variant could replace computation with t_PADICs or
t_POLMOD over Qp with fixed-point arithmetic using the modular kernel

4	3	src/basemath/buch2.c

13- ellpointtoz(E/Qp, P) accuracy issues

- more accurate that requested: faulty use of gprec() instead of gcvtop
- failures with division by 0 in low accuracy (catastrophic
  cancellation): restart at higher accuracy

Fix Qp_descending_Landen: f5d7bb5124 was too optimistic

confusion between v(r) and v(R) = v(r) - vA: R = r/p^vA decreases quadratically
but we are handling r and must adjust by vA.
