Trac #15860: spaces in function('A, B')

{{{
sage: function('A,B')

sage: A
A
sage: B

sage: function('C, D')
(C,  D)
sage: C

sage: D

NameError: name 'D' is not defined
}}}
IMHO {{{function('C, D')}}} should work, i.e., the function {{{D}}}
should be injected into the workspace.

The corresponding command with {{{var}}} works:
{{{
sage: var('c, d')
(c, d)
sage: c
c
sage: d
d
}}}

Further, the following works:
{{{
sage: C, D = function('C, D')
sage: C
C
sage: D
 D
}}}

This might also be related with the additional spacing, which occurs in
the following:
{{{
sage: C, D = function('C, D')
sage: C(D(x))
C( D(x))
}}}
(the space in {{{C( D(x))}}}, which should also be corrected (removed).

Trac #13626: implement gcd for padics

Currently, there is no gcd for padic numbers:
{{{
sage: R = Zp(3)
sage: R.one().gcd(R.zero())
AttributeError: 'sage.rings.padics.padic_capped_relative_element.pAdicCa
ppedRelativeElement' object has no attribute 'gcd'
}}}

The attached patch implements it.

Trac #16171: Sort cone facets

Cones already make sure that 1-d faces are sorted in the same way as
rays. Let's also make facets listed in the same order as facet normals:
the first of these lists is stored as is and the second one is sorted,
no matter in which order they are computed (facets can be determined
from the ambient structure without normals). The corner case when facets
are rays is handled as well by sorting facet normals immediately.
