gc_GEN_unsafe -> gc_upto

- removed obscure function cgetp

use high level cvtop or proper low level constructor
  mkpadic(u, padic_p(x), padic_pd(x), v, precp(x))
No need to copy p / pd or allocate a cgeti to later affii into u.
Also, one can use the correct value of v directly rather than hardcoding 0
then requiring a setvalp.

Add Flx pseudo-gp2c type

This allows to use GP2C to generate expressions in term
of Flx_add, Flx_mul, etc. by writing GP2C specific code like
fun(P:Flx,Q:Flx,p:usmall) = P*Q+Q^2

It uses implicitely the variable p.
