localprec: typo in documentation

localprec no longer returns the prec value

refactor the init_ser / fill_ser interface -> pol2ser

RgX_to_ser_*: comments + rename variable

12	9	src/basemath/Ser.c

fix issues with valuations of t_SER over non-domains

? a=Mod(3,9) + O(x); b=Mod(3,9) + O(x); a*b
%1 = Mod(0, 9)*x^-1 + O(x^0)
? a=Mod(3,9)*x^0; b=Mod(3,9) + O(x^2); a*b
%2 = Mod(0, 9)*x^-1 + O(x^0)
? a=Mod(3,9)*x^0; b=Mod(3,9) + O(x); a*b
%3 = Mod(0, 9)*x^-1 + O(x^0)

? a=Mod(3,9)+O(x^2); b=Mod(3,9) + O(x^2); print(a*b)
Mod(0, 9) + O(x^2) \\ not properly normalized

As well as returning the "wrong" 0:

? a=Mod(0,9)*x^0; b=Mod(1,2) + O(x); a*b
%4 = Mod(0, 9) \\ expected Mod(0,1)
