Primitive part of a polynomial : `primpart`

`primpart` takes as argument a polynomial `P` given by a
symbolic expression or by the list of it's coefficients.

`primpart` returns the primitive part of `P`,
that is `P` divided by the GCD
(greatest common divisor) of it's coefficients.

Input :
`primpart(6x``^`

2-3x+9)

or:
`primpart([6,-3,9],x))`

Output :
`2*x``^`

2-x+3
