weird pickling bug in padics

[sagetrac-dmharvey]

sage: K = pAdicField(5)
sage: x = K(0)
sage: y = loads(dumps(x))
sage: x.parent().print_prec()
 Infinity
sage: y.parent().print_prec()
 <class 'sage.rings.padic_field.pAdicField_generic'>

Component: basic arithmetic

Issue created by migration from https://trac.sagemath.org/ticket/305

Two more examples of weirdness:

sage: K = pAdicField(5)
sage: x = K(0)
sage: x.prec()
 Infinity
sage: y = loads(dumps(x))
sage: y.prec()
 <class 'sage.rings.padic_field.pAdicField_generic'>

and

sage: K = pAdicField(5)
sage: x = K(42)
sage: x.prec()
 Infinity
sage: y = loads(dumps(x))
sage: y.prec()
 '_pAdicField_generic__p'

This is fixed by David Roe's new p-adics in SAGE-2.3.
