32- [libpari] dblcnorm, dblcabs, dblcarg, dblclog

Rename and document functions dabs, darg, dnorm, dcxlog. The
(more robust) ISO C99 support for complex numbers could be used, but
this would have important drawbacks for our limited uses. Users can use
complex.h (and cabs, carg, clog) if they so wishes.

N.B. cabs, clog avoid intermediate overflow if possible; dblcabs and
dblclog won't (both compute dblcnorm(s+it) = s^2 + t^2 first, which may
overflow). Use glog / gabs stick to GENs if this is a problem.

gphelp.in: use single-quoted here-docs [#2621] (Emmanuel Thomé)

Configure replaces @version@ or @datadir@ by some (possibly weird)
character string. The resulting gphelp script assigns this to a perl variable.
Make sure no expansion takes place at this point by using here-docs.

29- [libpari] bnrconductor_factored_arch, bnrtoprimitive

Rewrite bnr_*_sanitize in terms of the new primitives.

Rewrite the old bnrconductor variants in terms of the new primitive
bnrconductor_factored_arch or bnrtoprimitive. Then a map can be created
using bnrsurjection and all appropriate objects mapped from the original
bnr representation to the primitive one.

The old (not properly documented) bnrconductormod is now static and
unused outside of the outdated bnrconductor and rnfconductor interface.
(Replaced by bnr_*_sanitize or low level bnrprimitive + bnrsurjection +
abmap_XXX functions)

simplify bnrconductor_factored_i usage

+ document proper use in comments
+ FIXME: bnrconductor_factored and bnrconductor_raw are probably not the
  best way to use bnrconductor_factored_i; we could probably drop them for
  a more flexible interface.
+ FIXME: remove bnrconductormod
+ TODO: the format [idealfactor(f0), foo] or [f0, foo] for idealstar and
  derived functions is not great. It forces either a factorization (bad) or
  a factorback (useless when f0 is known as an ideal, which is common). For
  instance we could allow [F0, foo] where F0 is either idealfactor(f0), f0,
  or [f0, idealfactor(f0)]
Possible use case: same f0, variable foo; for instance when the
conductor at infinity is smaller than the modulus but the finite
conductor is spot on, and we need to sanitize the bnr by one attacked to
the conductor.

24- lfun(bnr, vector of chars) -> impossible division [#2623]

The k characters have the same conductor F. The error could happen when they
had different orders [o1, ..., ok] and we initially computed
the ray class group bnr mod F, modulo o1-th powers. Must be done modulo
o-th powers, where o is the lcm(o1,...,ok).

10- remove bnrchar_primitive, bnrchar_primitive_raw.

Use bnrmap. Most of the time, the map can be precomputed: wasteful to do
it for each chi.
