64- bnfisprincipal(,1): e possibly uninitialized

Using either bnfinit(,1) or bnfisprincipal(,4), or both, is recommended
when the class group is huge and will compute the required principal part.

This commit fixes the initialization problem but is unlikely to allow
computing the generator (likely huge) when using suboptimal flags.

62- ZX_factor: rare "no factor" bug [#2670]

- use (Tra \ p^b) * M_L  instead of (Tra * M_L) \ p^b : the latter is
  "heuristically better" but the proven bounds don't necessarily apply;
  in the reported example, they don't.

- make sure to re-introduce the p^(a-b)*Id block after each reduction
  applied to the kapsack lattice

In principle, any of the above 2 issues could cause factors to be missed.
In #2670, the polynomial is actually irreducible; no reducible
counter-example was found but they are expected to exist.

cleanup and comment qfr_cf internals

- rename rho_get_BC_cf -> rhoi_cf, it actually applies rho^(-1)
  compared to rho_get_BC
- simplify interface: original a,b,c do not need to be kept in this
  application, so change all 3 in place.
